Resorbable screws versus pins for optimal transplant fixation (SPOT) in anterior cruciate ligament replacement with autologous hamstring grafts: rationale and design of a randomized, controlled, patient and investigator blinded trial [ISRCTN17384369]. (1/41)

BACKGROUND: Ruptures of the anterior cruciate ligament (ACL) are common injuries to the knee joint. Arthroscopic ACL replacement by autologous tendon grafts has established itself as a standard of care. Data from both experimental and observational studies suggest that surgical reconstruction does not fully restore knee stability. Persisting anterior laxity may lead to recurrent episodes of giving-way and cartilage damage. This might at least in part depend on the method of graft fixation in the bony tunnels. Whereas resorbable screws are easy to handle, pins may better preserve graft tension. The objective of this study is to determine whether pinning of ACL grafts reduces residual anterior laxity six months after surgery as compared to screw fixation. DESIGN/METHODS: SPOT is a randomised, controlled, patient and investigator blinded trial conducted at a single academic institution. Eligible patients are scheduled to arthroscopic ACL repair with triple-stranded hamstring grafts, conducted by a single, experienced surgeon. Intraoperatively, subjects willing to engage in this study will be randomised to transplant tethering with either resorbable screws or resorbable pins. No other changes apply to locally established treatment protocols. Patients and clinical investigators will remain blinded to the assigned fixation method until the six-month follow-up examination. The primary outcome is the side-to-side (repaired to healthy knee) difference in anterior translation as measured by the KT-1000 arthrometer at a defined load (89 N) six months after surgery. A sample size of 54 patients will yield a power of 80% to detect a difference of 1.0 mm +/- standard deviation 1.2 mm at a two-sided alpha of 5% with a t-test for independent samples. Secondary outcomes (generic and disease-specific measures of quality of life, magnetic resonance imaging morphology of transplants and devices) will be handled in an exploratory fashion. CONCLUSION: SPOT aims at showing a reduction in anterior knee laxity after fixing ACL grafts by pins compared to screws.  (+info)

Quantitative evaluation of anterior tibial translation during isokinetic motion in knees with anterior cruciate ligament reconstruction using either patellar or hamstring tendon grafts. (2/41)

We studied 79 patients with unilateral injury to the anterior cruciate ligament (ACL). The patients were randomly allocated to reconstruction with autologous patellar bone-tendon-bone (BTB) grafts (49 knees) or hamstring tendon (ST) grafts (30 knees). We measured anterior tibial translation (ATT) during isokinetic concentric contraction exercise 18-20 months after surgery using a computerized electrogoniometer. In both groups the highest ATT during exercise was observed at a knee flexion of about 20 degrees and was 13.5+/-3.0 mm in the BTB group and 13.9+/-3.4 mm in the ST group. There was no difference in the ATT between the reconstructed and healthy knees. For a range of knee flexion between 30 and 50 degrees the ATT in the ST group was significantly higher on the reconstructed side than on the healthy side. In the BTB group, the mean ATT in the reconstructed group was similar to that on the healthy side at a knee flexion angle between 0 and 90 degrees .  (+info)

Evaluation of tibial bone-tunnel changes with X-ray and computed tomography after ACL reconstruction using a bone-patella tendon-bone autograft. (3/41)

Thirteen patients who underwent anterior cruciate ligament (ACL) reconstruction with bone-patella tendon-bone autografts (BTB) using interference screws were the subjects of this study. We analysed the relationship between bone-tunnel changes and clinical results 2 years after ACL reconstruction. To investigate changes, X-ray images were used to evaluate bone-tunnel enlargement, and computed tomography (CT) was used to evaluate the sclerotic area around the bone tunnel. The KT-2000 was used to measure the discrepancy of tibial anterior displacement between the affected and nonaffected sides (DTAD). There was no correlation between bone-tunnel enlargement and DTAD. On the other hand, in the CT evaluation, there was a significant correlation between the sclerotic area and DTAD. Our results suggest that it is more significant to analyse the area of sclerotic change than bone-tunnel enlargement for clinical evaluation. We cannot evaluate bone-tunnel changes correctly with two-dimensional X-rays and cannot analyse the sclerotic area using X-rays. Therefore, we recommend that CT, with which it is possible to analyse the sclerotic area, be used to evaluate bone-tunnel changes and clinical results.  (+info)

Bone-patellar tendon-bone autografts versus hamstring autografts for reconstruction of anterior cruciate ligament: meta-analysis. (4/41)

OBJECTIVES: To compare bone-patellar tendon-bone autografts with hamstring autografts for reconstruction of the anterior cruciate ligament. DATA SOURCES: Medline, WebSPIRS, Science Citation Index, Current Contents databases, and Cochrane Central Register of Controlled Trials. Review methods All randomised controlled trials reporting one or more outcome related to stability (instrumented measurement of knee laxity, Lachman test, or pivot shift test) and morbidity (anterior knee pain, kneeling test, loss of extension, or graft failure). Study quality was assessed by using a 5 point scale. Random effect models were used to pool the data. Heterogeneity in the effect of treatment was tested on the basis of study quality, randomisation status, and number of tendon strands used. RESULTS: 24 trials of 18 cohorts (1512 patients) met the inclusion criteria. Study quality was poor for nine studies and fair for nine studies. The weighted mean difference of the instrumented measurement of knee laxity was 0.36 (95% confidence interval 0.01 to 0.71; P = 0.04). Relative risk of a positive Lachman test was 1.22 (1.01 to 1.47; P = 0.04), of anterior knee pain 0.57 (0.44 to 0.74; P < 0.0001), of a positive kneeling test 0.26 (0.14 to 0.48; P < 0.0001), and of loss of extension 0.52 (0.34 to 0.80; P = 0.003). Other results were not significant. CONCLUSION: Morbidity was lower for hamstring autografts than for patellar tendon autografts. Evidence that patellar tendon autografts offer better stability was weak. The poor quality of the studies calls into question the robustness of the analyses.  (+info)

The effect of interference screw diameter on soft tissue graft fixation. (5/41)

Tibial fixation of soft-tissue grafts is a weak link in anterior cruciate ligament reconstruction. Previous studies have examined varying interference screw lengths, screw types and tunnel sizes as means to improve graft fixation. We hypothesized that increasing interference screw diameter would significantly increase the maximum load to failure of the graft and decrease the graft's initial slippage. Seventy tibialis anterior and tibialis posterior tendons were divided, looped, trimmed, and sutured to simulate 4-strand hamstring grafts. These grafts were then inserted into composite bone blocks having pre-drilled 8 mm holes and fixed with 8 mm, 9 mm, 10 mm, 11 mm, or 12 mm interference screws. Fourteen grafts were tested for each screw size. The graft was first cyclically loaded from 50 N to 250 N at 0.3 Hz for 100 cycles to measure graft slippage. The graft was then tested to failure at 0.5 mm/sec to determine the maximum load to failure and mode of failure. Graft slippage was not affected by screw diameter. Maximum load to failure increased with increasing screw diameter up to 11 mm; 11 mm screw fixation was 20% stronger than 8 mm screw fixation. In this model, no increase in graft fixation was seen in by increasing interference screw diameter beyond 3 mm of the tunnel diameter.  (+info)

The interaction between the whipstitch sutures of multi-strand ACL grafts and interference screw fixation. (6/41)

In a recent experiment examining the effect of interference screw sizing on the fixation stability of multi-strand anterior cruciate ligament grafts, we noticed a large variation in fixation strengths and attributed it to the suturing of the grafts and its interaction with the screw. We performed an experiment using interference screws for fixation of hamstring grafts within a bone tunnel model to compare how the presence of sutures affected graft fixation. We found that having sutures along the region of the graft that contacts the screw within the bone tunnel can increase graft fixation strength 100%.  (+info)

The effect of graft choice on functional outcome in anterior cruciate ligament reconstruction. (7/41)

A prospective, randomised, 5-year follow-up study was designed to compare the functional results between patellar tendon and hamstring tendon autografts after anterior cruciate ligament reconstruction. Primary reconstruction was performed in 32 patients using the central third of the patellar ligament and in 32 patients using double-looped semitendinosus and gracilis tendons. All reconstructions were performed by a single surgeon, with identical surgical technique and rehabilitation protocol. Of the total 64 patients in the study, 54 (85%) were available for the 5-year follow-up. No statistically significant differences were seen with respect to Lysholm score, International Knee Documentation Committee (IKDC) classification, clinical and KT-2000 arthrometer laxity testing, single-legged hop test and anterior knee pain. Graft rupture occurred in two patients (8%) in the patellar tendon group and in two patients (7%) in the hamstring tendon group; 23 patients (88%) in the patellar tendon group and 23 patients (82%) in the hamstring tendon group returned to their pre-injury activity level. Good subjective outcome and stability can be obtained by using either graft; no statistically significant differences were found in functional outcome between the grafts.  (+info)

Proprioceptive skills and functional outcome after anterior cruciate ligament reconstruction with a bone-tendon-bone graft. (8/41)

Several studies have shown that patients with anterior cruciate ligament (ACL) reconstruction have an improved proprioceptive function compared to subjects with ACL-deficient knees. The measurement of functional scores and proprioception potentially provides clinicians with more information on the status of the ACL-reconstructed knees. To evaluate proprioception in patients following ACL reconstruction with a bone-tendon-bone (BTB) graft, we used the angle reproduction in the sitting, lying and standing positions and the one-leg hop test. Forty-five patients between 19 and 52 years of age were investigated in a 36-month period after the operation. For functional performance measurement, the International Knee Documentation Committee (IKDC) score was used. Very good and good results were seen in 95% of cases. All patients returned to the same activity level as seen before ACL repair. There was a significant difference in the active angle reproduction test between the ACL-reconstructed knees and normal knees in the active sitting position. Tests with passive angle adjustment in the sitting, lying and active standing positions did not show any differences in proprioceptive skills. Good to very good results in the one-leg hop test we found in 95% of patients. After ACL reconstruction, deficiencies in the active angle reproduction test were very small but, nevertheless, were still observed. Overall, the functional and proprioceptive outcomes demonstrate results to recommend the procedure.  (+info)

This study investigated whether gene transfer to the tendon-bone insertion site is possible during early tendon-transplant healing using viral vectors. In addition, we evaluated the optimal gene delivery technique for an in vivo adenoviral gene transfer to a tendon-bone insertion site in a bone tunnel. Twenty-six rabbits underwent a bilateral transfer of the flexor digitorum longus tendon into a bone canal in the calcaneus. The animals were divided into two groups. The first group (n=18) received a direct injection of an adenoviral vector carrying the luciferase marker gene into the tendon on the left side, while on the right side the adenoviral vector was first injected into the bone trough and the tendon was later inserted into the trough. The analysis of this experiment showed that over a 4-week period a higher luciferase activity was achieved using the bone trough immersion technique. In the second group (n=8) we therefore used the qualitative marker virus (Ad/-LacZ) with the bone trough ...

Background: Currently in double-bundle anterior cruciate ligament (ACL) reconstructions, the range of knee flexion angles that surgeons use for anteromedial (AM) and posterolateral (PL) bundle graft fixation spans from 0° to 90° for both bundle grafts. Despite the recent popularity of this procedure, no consensus exists on an optimal set of AM and PL graft fixation angles.. Hypothesis: Graft fixation angles that simulate the native tensioning relationship of the AM and PL bundles will produce kinematic results similar to the intact knee, while graft fixation angles that do not simulate this relationship will under- or overconstrain the knee.. Study design: Controlled laboratory study.. Methods: Twelve cadaveric knees were biomechanically tested in the intact state, ACL-sectioned state, and a randomized order of 7 double-bundle ACL reconstructed states at multiple graft fixation angle combinations. For each test state, data were collected for 88 N anterior tibial loads, 10 N·m valgus torques, ...

3.3.1] The [patent proprietor] argued in this respect that according to page 11, lines 36-37 of the opposed patent, polyethylene terephthalate on the market had an LTC temperature of 128°C. In order to identify the heating rate applied in the opposed patent, the skilled person therefore simply had to calibrate the DSC measurement and in particular the heating rate with the help of the polyethylene terephthalate resin on the market such that an LTC temperature of 128°C resulted. The heating rate thereby determined was the heating rate applied in the opposed patent. The [patent proprietors] argument logically implies that at the filing date of the opposed patent either only one polyethylene terephthalate resin was available on the market or all polyethylene terephthalate resins available on the market had the same LTC temperature of 128°C. As set out by the [opponent] and as also acknowledged by the [patent proprietor], this was however not the case. Actually, polyethylene terephthalate ...

Experimental and numerical analysis of screw fixation in anterior cruciate ligament reconstruction - -This paper reports the results of an experimental and finite element analysis of tibial screw fixation in hamstring ACL reconstruction. The mechanical properties of the bone and tendon graft are obtained from experiments using porcine/calf bones and tendon. The results of the numerical study are compared with those from mechanical testing. 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.

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 ...

Minimising post-operative donor site morbidity is an important consideration when selecting a graft for surgical reconstruction of the torn anterior cruciate ligament (ACL). One of the most common procedures, the bone-patellar tendon-bone (BPTB) graft involves removal of the central third from the tendon. However, it is unknown whether the mechanical properties of the donor site (patellar tendon) recover. The present study investigated the mechanical properties of the human patellar tendon in 12 males (mean+/-S.D. age: 37+/-14 years) who had undergone surgical reconstruction of the ACL using a BPTB graft between 1 and 10 years before the study (operated knee; OP). The uninjured contralateral knee served as a control (CTRL). Patellar tendon mechanical properties were assessed in vivo combining dynamometry with ultrasound imaging. Patellar tendon stiffness was calculated from the gradient of the tendons force-elongation curve. Tendon stiffness was normalised to the tendons dimensions to obtain ...

Endosteal fixation of a ligament graft with a bioabsorbable interference screw installed in a retrograde manner in ACL reconstruction. The bioabsorbable interference screw is insert-molded with a length of suture extending from the distal tip of the screw for pulling the interference screw into the joint and into position for retrograde insertion at the top of the tibial tunnel. The interference screw has a cannulation extending partially through the screw from the leading tip. The cannulation is shaped to receive a correspondingly shaped driver. The driver is inserted into the tibial tunnel to engage the screw. By turning the driver, the interference screw is turned into the tibial tunnel in a retrograde manner. Accordingly, interference fixation of the graft near the tibial plateau is provided, thereby eliminating graft abrasion at the tibial plateau tunnel opening.

I was in Japan skiing with my family in January 2020. It was the second day of the trip when I got injured and ruptured my ACL.. Ive skied every year of my life, basically, so Im a very confident skier. Im not a beginner at all. Ive skied a lot. But I fell and noticed there was a really loud noise in my knee. I knew something was wrong then. I stood up and my whole knee caved in. At that point, I knew I couldnt ski down the mountain myself.. We called mountain rescue and they took me down in a Ski-Doo, which is a type of skimobile. From there, they took me straight to the clinic. Luckily, the resort we were at is quite popular among Australians, so I was able to find a doctor that spoke English. The language barrier wasnt really an issue.. My knee didnt really hurt at that point. It wasnt a painful injury, though my body was in a lot of shock. At the clinic, they put me in a knee brace and sent me home with some painkillers. We then organised an MRI scan.. Originally, my plan had been to ...

In July 1995 I had ACL repair surgery. I developed a MRSA infection within two weeks, and spent further time in the hospital being treated for that, undergoing surgery to insert drains in the infected knee, and upon discharge having whirlpool therapy in an effort to halt the infection, as well as antibiotic treatment. In September the same surgeon operated again to remove some of the hardware at the site of the infection, which had begun in the tibia.. In the fall of 1997 I developed cellulitis in the same leg, which was found to be [the same?] MRSA; the button used to affix the tendon repair to my femur had come loose, and had migrated to the inside surface of my knee. At this time I went to a doctor other than the original surgeon. In reading my records, this doctor discovered that at the surgery to remove the tibia hardware in September of 97, the surgeon had noted gross pus at the site. Yet I was never told of this nor did the original surgeon prescribe any course of antibiotics at that ...
