Reconstruction of the anterior cruciate ligament: comparison of outside-in and all-inside techniques. (1/1002)

The aim of this prospective study was to compare two arthroscopic techniques for reconstructing the anterior cruciate ligament, the "outside-in" (two incisions) and the "all-inside" (one incision) techniques. The results obtained for 30 patients operated on using the "outside-in" technique (group I) were compared with those for 29 patients operated on using the "all-inside" technique (group II). Before surgery, there were no significant differences between the groups in terms of Lysholm score, Tegner activity level, patellofemoral pain score, or knee laxity. Both groups displayed significant improvements in Lysholm score after 24 months, from 69 (16) to 91 (9) in group I and from 70 (17) to 90 (15) in group II (means (SD)). There were also significant improvements in patellofemoral pain scores in both groups, from 13 (6) to 18 (5) in group I and from 14 (6) to 18 (4) in group II after 24 months. No difference was found between the groups in knee stability at the 24 month follow up. The IKDC score was identical in both groups at follow up. The operation took significantly longer for patients in group I (mean 94 (15)) than for those in group II (mean 86 (20)) (p = 0.03). The mean sick leave was 7.7 (6.2) weeks in group I and 12.3 (9.7) weeks in group II (p = 0.026), indicating that there may be a higher morbidity associated with the "all-inside" technique. It can be concluded that there were no significant differences between the two different techniques in terms of functional results, knee laxity, or postoperative complications. The results were satisfactory and the outcome was similar in both treatment groups.  (+info)

Neurogenic origin of articular hyperemia in early degenerative joint disease. (2/1002)

It has been speculated that joint instability resulting from anterior cruciate ligament (ACL) rupture could be exacerbated by changes in vasomotor activity in the remaining supporting structures. In this study, the effect of ACL transection on medial collateral ligament (MCL) basal perfusion and its responsiveness to calcitonin gene-related peptide (CGRP) and sympathetic adrenergic influences was examined. Using urethan-anesthetized rabbits, we tested the effects of CGRP and its antagonist CGRP-(8-37) by topical application of these agents to the exposed knee while sympathetic influences were tested by electrically stimulating the saphenous nerve. It was found that MCL basal perfusion was elevated in ACL-sectioned joints; however, this effect was abrogated by prior resection of the articular nerve supply. At the doses tested, the normal vasodilator response to CGRP was abolished in ACL-sectioned joints, whereas the response to CGRP-(8-37) was attenuated. Even under the influence of increased constrictor tone, MCL and capsule blood vessels still showed substantially reduced responses to exogenous CGRP administration. By contrast, nerve-mediated constrictor responses were mostly unaffected by joint instability. This study suggests that posttraumatic knee joint hyperemia is neurogenically mediated, possibly by increased secretion of CGRP.  (+info)

Diacerhein treatment reduces the severity of osteoarthritis in the canine cruciate-deficiency model of osteoarthritis. (3/1002)

OBJECTIVE: To determine if diacerhein protects against the early stages of joint damage in a canine model of osteoarthritis (OA). METHODS: OA was induced in 20 adult mongrel dogs by transection of the anterior cruciate ligament of the left knee. Beginning the day after surgery, dogs in the active treatment group were dosed twice a day with capsules of diacerhein, providing a total daily dose of 40 mg/kg, for 32 weeks. Dogs in the control group received placebo capsules on the same schedule. Pathology in the unstable knee was assessed arthroscopically 16 weeks after surgery and by direct observation when the dogs were killed 32 weeks after surgery. The severity of gross joint pathology was recorded, and samples of the medial femoral condyle cartilage and the synovial tissue adjacent to the central portion of the medial meniscus were collected for histologic evaluation. Water content and uronic acid concentration of the articular cartilage from the femoral condyle were determined, and collagenolytic activity in extracts of cartilage pooled from the medial and lateral tibial plateaus was assayed against 14C-labeled collagen fibers. RESULTS: Diacerhein treatment slowed the progression of OA, as measured by grading of gross changes in the unstable knee at arthroscopy 16 weeks after cruciate ligament transection (P = 0.04) and at the time the animals were killed, 32 weeks after surgery (P = 0.05). However, 32 weeks after ACL transection, the mean proteoglycan concentration and water content of the OA cartilage and the level of collagenolytic activity in extracts of the cartilage were not significantly different in the diacerhein treatment group than in the placebo treatment group. CONCLUSION: Diacerhein treatment significantly reduced the severity of morphologic changes of OA compared with placebo. These findings support the view that diacerhein may be a disease-modifying drug for OA.  (+info)

Effects of aggressive early rehabilitation on the outcome of anterior cruciate ligament reconstruction with multi-strand semitendinosus tendon. (4/1002)

To evaluate the effects of aggressive early rehabilitation on the clinical outcome of anterior cruciate ligament reconstruction using semitendinosus (and gracilis) tendon, 103 of 110 consecutive patients who underwent ACL reconstruction using multistrand semitendinosus tendon (ST) or the central one-third of patellar tendon with bony attachments (BTB) were analyzed prospectively. Subjectively, the Lysholm score was not different among the groups. The Lachman test indicated a trend of less negative grade in the ST men's group than that in the BTB men's group. On the patellofemoral grinding test, only women patients of both groups showed pain, with less positive crepitation in the ST group than in the BTB group. KT measurements at manual maximum showed more patients with more than 5 mm differences in the ST group than in the BTB group. The results of this study suggest that aggressive early rehabilitation after the ACL reconstruction using the semitendinosus (and gracilis) tendon has more risk of residual laxity than with the BTB.  (+info)

The effects of hyaluronan on matrix metalloproteinase-3 (MMP-3), interleukin-1beta(IL-1beta), and tissue inhibitor of metalloproteinase-1 (TIMP-1) gene expression during the development of osteoarthritis. (7/1002)

OBJECTIVE: To assess the influence of intra-articular injection of hyaluronan (HA) on expression of matrix metalloproteinase-3 (MMP-3), interleukin-1beta(IL-1beta), and tissue inhibitor of metalloproteinase-1 (TIMP-1) in cartilage and synovium during the process of osteoarthritis (OA). DESIGN: Eighteen mature New Zealand white rabbits underwent unilateral anterior cruciate ligament transection (ACLT) and were divided into two groups. The first group (HA injection group) received 0.3 ml of intra-articular HA injections into the ACLT knees 4 weeks after transection, once a week for 5 weeks as per clinical treatment presently utilized. The animals in the second group (no injection group) were not injected after ACLT. At death, 9 weeks following surgery, synovium and cartilage were harvested and total RNA was extracted. Gene expressions of MMP-3, IL-1beta and TIMP-1 were analyzed using reverse transcription-polymerase chain reaction (RT-PCR) for each subgroup created according to morphological grade of OA. RESULTS: The extent and grade of cartilage damage in the HA injection group was less severe than in the no injection group. In synovium, expression of MMP-3 and IL-1beta mRNA was suppressed in the mild grades of OA in the HA injection group. HA treatment had either no effect on MMP-3 expression in cartilage at all grades of OA or on enhanced MMP-3 and IL-1beta expression in synovium at a progressed grade. No effect of HA treatment on TIMP-1 expression was observed in either cartilage or synovium. CONCLUSIONS: These results suggest that one of the mechanism of therapeutic effect of HA is down-regulation of MMP-3 and IL-1beta in synovium during early development of OA.  (+info)

Treatment with calcitonin suppresses the responses of bone, cartilage, and synovium in the early stages of canine experimental osteoarthritis and significantly reduces the severity of the cartilage lesions. (8/1002)

OBJECTIVE: To relate the rate of bone resorption to serum levels of both hyaluronan (HA) and antigenic keratan sulfate (KS) in canine experimental osteoarthritis (OA) and to evaluate the effects of calcitonin on these parameters and the OA lesions of the unstable knee. METHODS: Twenty-two dogs underwent anterior cruciate ligament transection (ACLT) and 6 dogs underwent sham operation. Urinary pyridinium crosslinks were quantified by high-performance liquid chromatography. Immunoassays quantified hyaluronan (HA) and antigenic KS. Macroscopic and histologic OA lesions were scored. Calcitonin treatment was started on day 14 postsurgery and stopped on either day 49 or day 104 postsurgery. Control dogs and all treated dogs were killed on day 105. RESULTS: All ACLT joints developed OA. In contrast to sham-operated animals, all operated dogs exhibited an early and sustained rise in the levels of their urinary and serum markers. Calcitonin markedly reduced the levels of these markers and the severity of OA lesions. Furthermore, the longer the period of calcitonin therapy, the lower the score of the OA lesions. CONCLUSION: Bone, synovium, and articular cartilage all appear to be involved in the state of hypermetabolism that develops in unstable joints. Furthermore, the rate of bone resorption increases markedly in the early stages of this OA model and is likely to contribute to cartilage breakdown. Since calcitonin reduced the severity of OA changes, this form of therapy may have benefits for humans who have recently experienced a traumatic knee injury.  (+info)

BACKGROUND The anterior cruciate ligament-deficient knee is prone to osteoarthritis and meniscus lesions. Very little, however, is known about the biomechanical properties of articular cartilage in anterior cruciate ligament-deficient knees. PURPOSE To evaluate biomechanical and macroscopical cartilage changes in the knee joint with respect to the time after anterior cruciate ligament rupture. HYPOTHESIS Chronic anterior cruciate ligament deficiency induces cartilage softening. STUDY DESIGN Cross-sectional study; Level of evidence, 3. METHODS Cartilage stiffness of 50 patients undergoing anterior cruciate ligament reconstructive surgery because of symptomatic knee instability after chronic anterior cruciate ligament rupture was measured with an arthroscopic indenter device, and the number and size of cartilage lesions were evaluated. RESULTS The cartilage stiffness did not correlate with time from trauma to surgery (r = 0.002, P = .99), but the number of cartilage lesions in the knee increased
TY - JOUR. T1 - Quadriceps tendon-patellar bone autograft for arthroscopic anterior cruciate ligament reconstruction. AU - Chen, C. H.. AU - Chen, W. J.. AU - Shih, C. H.. AU - Jiang, C. C.. PY - 1998. Y1 - 1998. N2 - Surgical reconstruction of the anterior cruciate ligament (ACL) is indicated in ACL-deficient knee with symptomatic instability and multiple ligament injuries. Bone-patellar tendon-bone and hamstring tendon have been generally used in the reconstructive surgeries. However, the advantages and the disadvantages of these graft tissues continues to be controversial. An arthroscopic ACL reconstruction technique is described in the present study by using an alternative graft method called the quadriceps tendon-patellar bone autograft. From March 1996 to March 1997, this autograft was used in 12 patients with ACL injuries. After 1 to 2 years of follow-up, the clinical outcome of the patients treated with this graft have been encouraging. The advantages of the quadriceps tendon graft ...

Aim: The purpose of the study was to improve the ultrasonographic assessment of the anterior cruciate ligament by an inclusion of a dynamic element. The proposed functional modification aims to restore normal posterior cruciate ligament tension, which is associated with a visible change in the ligament shape. This method reduces the risk of an error resulting from subjectively assessing the shape of the posterior cruciate ligament. It should be also emphasized that the method combined with other ultrasound anterior cruciate ligament assessment techniques helps increase diagnostic accuracy. Methods: Ultrasonography is used as an adjunctive technique in the diagnosis of anterior cruciate ligament injury. The paper presents a sonographic technique for the assessment of suspected anterior cruciate ligament insufficiency supplemented by the use of a dynamic examination. This technique can be recommended as an additional procedure in routine ultrasound diagnostics of anterior cruciate ligament ...
Arthroscopic anterior cruciate ligament reconstruction using the double press- fit technique: an alternative to interference screw fixation.: The double press-f
Anterior cruciate ligament injury is a common and serious knee injury. ACL deficiency can lead to symptomatic instability with possibly more intra-articular damage and accelerated degenerative joint disease. These assumptions are not supported by outcomes of clinical studies that report that mid- and long-term outcomes are equal for operatively and non-operatively treated patients with regard to patient related outcome measurements and osteoarthritis. Whether arthroscopic anterior cruciate ligament reconstruction results in better patient reported outcomes than nonoperative treatment followed by an optional reconstruction is unclear. Primary research question is whether is a clinical relevant difference in change in International Knee Documentation Committee (IKDC) questionnaire over a period of 24 months of an early surgical intervention versus a more conservative management of patients with a complete ACL rupture? ...

Analysis shows that the model may be used to establish the optimum placement of the tunnel in anterior cruciate ligament reconstruction by predicting mechanical parameters such as stress, strain and displacement at regions in the tunnel wall.
0005]Single tunnel single bundle anterior cruciate ligament reconstruction (STSBACLR) has long been established as a method of anterior cruciate ligament (ACL) reconstruction. A variety of graft choices are available to surgeons during ACL reconstruction. These choices include autogenous patellar or quadriceps tendon with bone blocks, or hamstring tendons. In addition, changed here tendon allografts (from donors) may be used. The main portion of the ACL which needs to be reconstructed is the anterolateral bundles. Arthroscopic assisted or open ACL reconstructions involve removing the remaining native ACL and drilling a tunnel at the anatomic attachment site of the anterolateral or posterior medial bundle at the anterolateral wall of the intercondylar notch. This tunnel is drilled in line with the roof of the notch and about 1-3 mm from the posterior articular surface of the lateral femoral condyle. The tibial attachment site is then prepared by identifying the normal attachment site of the ACL ...

TY - JOUR. T1 - Anatomic anterior cruciate ligament double-bundle reconstruction using 2 tibial and 2 femoral tunnels. AU - Ferretti, Mario. AU - Zelle, Boris A.. AU - Chhabra, Anikar. AU - Fu, Freddie H.. PY - 2005/9/1. Y1 - 2005/9/1. N2 - Over the last decade, anterior cruciate ligament (ACL) reconstruction has been continuously improved. Although the current outcomes of the single-bundle ACL reconstruction are good, there remains significant room for improvement. A high percentage of patients do not return to their previous level of activity, and progressive cartilage degeneration continues to be a common problem after ACL injury. The evaluation of the 3-dimensional in vivo kinematics of the knee joint after single-bundle ACL reconstruction has demonstrated good restoration of the anteroposterior stability, whereas the rotational stability cannot be restored. Similarly, biomechanical studies in cadavers reveal that anatomic double-bundle ACL reconstruction restores the rotational knee ...

N2 - Anterior cruciate ligament (ACL) ruptures are some of the most common knee injuries seen by sports medicine physicians. However, given the complex anatomy and function of the ACL, reconstruction of this ligament is anything but straightforward. The last decade has seen much advancement in ACL reconstruction, with an improved knowledge of the biology and biomechanics of graft incorporation, new choices for graft material and graft fixation devices, and more accelerated rehabilitation protocols. Although there are numerous studies in the literature on ACL reconstruction, there is yet to be a consensus among surgeons on the best graft choice and ...

Background. The anterior cruciate ligament (ACL) is a band of tough tissue inside the knee that helps stabilise the knee during movement. Rupture of the ACL is a common injury during some sporting activities, such as football and skiing. Anterior cruciate ligament injuries are often treated surgically. This usually involves keyhole (arthroscopic) ACL reconstruction, where the torn ACL is replaced by a piece of tendon (graft). The graft is usually extracted from another place near the patients affected knee. In ACL reconstruction, bone tunnels are drilled at the knee into the tibia (shin bone) and the femur (thigh bone) to place the ACL graft in almost the same position as the torn ACL.. This review compared two ACL reconstruction techniques: one-incision versus two-incision. The more common two-incision technique involves drilling the femoral (from the thigh bone) tunnel from outside to inside the knee joint with an incision made in the outward aspect of the thigh to reach the bone. In the ...

Injuries to the anterior cruciate ligament are common. Surgical reconstruction is more prevalent than ever. This review article discusses treatment of the patient following surgical reconstruction of the anterior cruciate ligament. Various phases of rehabilitation are discussed with emphasis on early return of passive motion, early weight bearing, bracing, kinetic chain exercises, neuromuscular electrical stimulation and accelerated rehabilitation. Although evidence exists for the treatment of the surgically reconstructed cruciate ligament, more is needed to better define specific timeframes for advancement. Evidence exists that many of these young individuals are not fully returning to unlimited high level activities. This review article presents some of the latest evidence regarding anterior cruciate ligament rehabilitation in an attempt to help the busy clinician understand and relate basic and clinical research to rehabilitation of a patient following reconstruction ...

We aimed to evaluate clinical and radiological results after simultaneous open-wedge high tibial osteotomy (HTO) and anterior cruciate ligament (ACL) reconstruction in patients with ACL deficiency combined with medial uni-compartmental osteoarthritis (OA) and varus deformity. This retrospective study was performed using data collected from 2005 to 2011 on a total of 24 patients who were diagnosed with ACL injury and medial unicompartmental OA with varus deformity, and who subsequently underwent simultaneous open-wedge HTO and arthroscopic ACL reconstruction. The mean follow-up duration was 5.2 years. For clinical outcomes, we evaluated Lysholm score, Tegner activity score, range of motion, Lachmann test, and pivot-shift test, and for radiological outcomes, we evaluated the degree of varus deformity, progression of medial OA, tibial posterior slope, anterior instability, and postoperative complication. There were no limitations in range of motion found in any cases. Three patients showed progressive

A prospective study was performed on 30 patients who underwent an anterior cruciate ligament reconstruction with fresh-frozen patellar tendon allograft. An arthroscopic technique alone was used in 10 patients, and in the other 20 patients this was combined with a miniarthrotomy.. After a mean follow up of 35 months, the overall functional results were satisfactory in 85%. There were no cases of infection, disease transmission or tissue rejection. Fresh-frozen patellar tendon allografts are a good method of anterior cruciate reconstruction.. CITATION Int Orthop. 1994;18(4):210-4. ...
The purpose of the current analysis was to determine which PNMT exercises had a greater prophylactic effect in clinical trials that aimed to reduce ACL injury in young females. Four exercise categories, balance, plyometrics, strength and proximal control training, were examined. The results indicated that clinical trials that instituted PNMT with strength and proximal control training demonstrated the greatest prophylactic effects. Prophylactic effects were not statistically different between PNMT with and without plyometrics, but greater ACL injury reduction was recorded in PNMT with plyometrics. More specifically, incorporating plyometrics, strengthening and proximal control training into PNMT programmes can lead to ACL injury risk reduction by 61% in plyometrics, 68% in strengthening, and 67% in proximal control in young females. Balance exercises demonstrated a 41% reduction in ACL injury rate compared to a 66% reduction by PNMT without balance exercises (figure 2).. Plyometric exercises in ...
The anterior cruciate ligament (ACL) is one of a pair of cruciate ligaments (the other being the posterior cruciate ligament) in the human knee. The two ligaments are also called cruciform ligaments, as they are arranged in a crossed formation. In the quadruped stifle joint (analogous to the knee), based on its anatomical position, it is also referred to as the cranial cruciate ligament. The anterior cruciate ligament is one of the four main ligaments of the knee, providing 85% of the restraining force to anterior tibial displacement at 30 degrees and 90 degrees of knee flexion. The ACL originates from deep within the notch of the distal femur. Its proximal fibers fan out along the medial wall of the lateral femoral condyle. There are two bundles of the ACL: the anteromedial and the posterolateral, named according to where the bundles insert into the tibial plateau. (The tibia plateau is a critical weight-bearing region on the upper extremity of the tibia). The ACL attaches in front of the ...

Ideal conditions for healing are mostly non-existent in one of the most common sports-related injury, the anterior cruciate ligament (ACL) tear.[1] Furthermore, there are still controversies in regards to the optimal management of a torn ACL and the optimal time for return to sports following ACL reconstruction.. At a mean of six months after ACL reconstruction, objective functional recovery of the knee was generally unsatisfactory and this seemed to be a risk factor for recurrent tears.[2] A systematic review and meta-analysis demonstrates that younger age and return to high level of activity are evident factors leading to recurrent ACL tears.[3] These combined data indicate that nearly one in four young athletic patients who sustain an ACL injury and return to high-risk sports will develop another ACL injury.[3]. The ACL reconstruction does not necessarily enable return to preinjury sports participation. By returning to pivoting sports after ACL reconstruction, athletes are also facing high ...
The hyperflexion required for femoral tunnel drilling in anterior cruciate ligament reconstruction can be challenging in patients with increased body habitus or musculature. Whilst allowing femoral tunnel creation without hyperflexion, additional benefits of flexible reamers have been proposed in terms of tunnel dimensions. The purpose of this study was to examine whether these theoretical benefits are seen in a clinical study ...
Background: Anterior cruciate ligament reconstructions (ACLRs) are frequently performed on young, active patients and can result in persistent knee symptoms and activity limitations that may affect health-related quality of life (HRQoL). To date, there has been no systematic review of HRQoL outcomes after ACLR. Purpose: The objectives of this study were to report HRQoL ≥5 years after ACLR, compare HRQoL outcomes with available population norms, and describe factors that may affect HRQoL in this population. Study Design: Systematic review. Methods: All studies reporting HRQoL ≥5 years after ACLR with hamstring or patellar tendon autografts were eligible for review. Common HRQoL outcomes were pooled using a random-effects meta-analysis and compared with published population norms. The Spearman rank correlation coefficient (r) was used to identify variables associated with HRQoL outcomes. Where insufficient data were available, outcomes were reported descriptively. Results: Fourteen studies ...
All-Inside Versus Inside-Out Meniscal Repair With Concurrent Anterior Cruciate Ligament Reconstruction: A Meta-regression Analysis .
Several meta-analyses have been published on the effectiveness of anterior cruciate ligament (ACL) injury prevention training programs to reduce ACL injury risk, with various degrees of risk reduction reported. The purpose of this research was to perform a systematic review and meta-analysis of overlapping meta-analyses evaluating the effectiveness of ACL injury prevention training programs so as to summarize the amount of reduction in risk for all ACL and non-contact ACL injuries into a single source, and determine if there were sex differences in the relative efficacy of ACL injury prevention training programs. Five databases (Medline, PubMed, Embase, CINAHL, and Cochrane) were searched to identify meta-analyses that evaluated the effectiveness of ACL injury prevention training programs on ACL injury risk. ACL injury data were extracted and the results from each meta-analysis were combined using a summary meta-analysis based on odds ratios (OR). Eight meta-analyses met eligibility criteria. ...
The purpose of this study was to evaluate the hypothesis that early motion increases tibial tunnel enlargement in patients who underwent anterior cruciate ligament (ACL) replacement with hamstring autograft. Cohort analytic study. All patients in this study had received a doubled semitendinous and gracilis graft. Grafts were secured in place with an implantfree technique. Two groups of patients were evaluated. Group A consisted of 35 patients who underwent isolated ACL replacement and whose rehabilitation protocol included early motion. Group B consisted of 20 patients who underwent combined arthroscopic meniscal repair and ACL replacement. Partial weight bearing and restriction of range of motion for 6 weeks was recommended for these patients. The only 2 variables between the groups were the meniscal repair and the postoperative rehabilitation. Patients were evaluated clinically and radiographically at 3, 6, and 12 months postoperatively. After correction for radiographic magnification, the ...
Successful anterior cruciate ligament reconstruction with a tendon graft necessitates solid healing of the tendon graft in the bone tunnel. Improvement of graft healing to bone is crucial for facilitating an early and aggressive rehabilitation and ensuring rapid return to pre-injury levels activity. Tendon graft healing in a bone tunnel requires bone ingrowth into the tendon. Indirect Sharpey fiber formation and direct fibrocartilage fixation confer different anchorage strength and interface properties at the tendon-bone interface. For enhancing tendon graft-to-bone healing, we introduce a strategy that includes the use of periosteum, hydrogel supplemented with periosteal progenitor cells and bone morphogenetic protein-2, and a periosteal progenitor cell sheet. Future studies include the use of cytokines, gene therapy, stem cells, platelet-rich plasma, and mechanical stress for tendon-to-bone healing. These strategies are currently under investigation, and will be applied in the clinical setting in the

There is a greater risk of tibial component loosening when mobile unicompartmental knee replacement is performed in anterior cruciate ligament deficient knees. We previously reported on a cohort of anterior cruciate ligament deficient patients (n=46) who had undergone surgery, but no difference was found in implant survivorship at a mean 5-year follow-up. The purpose of this study was to examine the kinematic behaviour of a subcohort of these patients.The kinematic behaviour of anterior cruciate deficient knees (n=16) after mobile unicompartmental knee replacement was compared to matched intact knees (n=16). Sagittal plane knee fluoroscopy was taken while patients performed step-up and forward lunge exercises. The patellar tendon angle, knee flexion angle and implant position was calculated for each video frame.The patellar tendon angle was 5° lower in the deficient group, indicating greater anterior tibial translation compared to the intact group between 30 and 40° of flexion. Large variability,
Background:The main goal of physiotherapy for patients with anterior cruciate ligament reconstruction (ACL-R) is to improve postural control and retain knee function. Therefore, clinicians need to use evaluative tools that assess postural changes during physiotherapy. To maximize the clinical utility of the results of these tools, the extracted measures should have appropriate psychometric properties of reliability, validity and responsiveness. No study has yet addressed responsiveness of postural measures in these patients. This study was designed to investigate the responsiveness and determine the minimal clinically important changes (MCIC) of static and dynamic postural measures in patients with (ACL-R) following physiotherapy. Methods: Static and dynamic postural measures were evaluated at first occasion and again after four weeks physiotherapy. The static measures consisted of center of pressure (COP) parameters while dynamic measures included the stability indices. Correlation analysis and ROC

Anterior Cruciate Ligament injuries are common knee injuries that need proper non-surgical and maybe surgical treatment. When an ACL injury occurs, the knee becomes less stable. Such instability will make sudden pivoting movements difficult. This type of damage to the knee may also make you prone to developing arthritis and cartilage tears.The symptoms of an ACL injury may include a sudden giving way of the knee, a
