Outcomes1
Ligamentous2
- Because the ACL is intra-articular, the ligamentous ends are subjected to synovial fluid, which does not support ligamentous healing. (medscape.com)
- We recruited patients who underwent anterior cruciate ligament reconstruction, with or without other ligamentous reconstruction, in a single tertiary institution. (isakos.com)
Maneuvers2
- Lateral Extra-articular Tenodesis Alters Lateral Compartment Contact Mechanics under Simulated Pivoting Maneuvers: An In Vitro Study. (hss.edu)

Proximal1
- We compared the relative positions and orientations of the wrist bones after two surgical procedures intended to repair a ruptured scapholunate ligament: the dorsal fiber-splitting capsulotomy (FSC) approach intended to preserve the dorsal ligaments of the proximal row of wrist bones and a new dorsal window approach being developed by surgeons at HSS. (hss.edu)
Lateral1
- Varus stress radiographs obtained at 6 months post-operatively demonstrated resolution of lateral knee stability. (drrobertlaprademd.com)
Biomechanics1
- The disconnect between computational studies of biomechanics of total knee arthroplasty (TKA) at the whole joint level and those focused on the interface level between the implants and the surrounding bone hinders our understanding of TKA function as a whole and prevents identifying tradeoffs between these levels. (hss.edu)
Tear2
- p>Izzy is one of thousands of high school athletes each year who tear their ACLs, or anterior cruciate ligaments. (massgeneralbrigham.org)
- The knee often swells immediately, or shortly after, a tear, and the pain varies from person-to-person. (massgeneralbrigham.org)
Repair5
- We found that the FSC can create deleterious changes in wrist posture while the new window approach does not alter the posture and should be considered when performing ligament repair. (hss.edu)
- The methods of surgical repair may be categorized into 3 groups: primary repair, extra-articular repair, and intra-articular repair. (medscape.com)
- Extra-articular repair generally involves a tenodesis of the iliotibial tract. (medscape.com)
- An anterior cruciate ligament repair was also performed. (drrobertlaprademd.com)
- Dr LaPrade performed a deep root repair to my meniscus, which saved me from a knee replacement at this time. (drrobertlaprademd.com)
Graft5
- Both the position in which a sports medicine surgeon places an anterior cruciate ligament (ACL) graft within the anatomic femoral footprint of the native ACL and the flexion angle at which the graft is fixed are important considerations in ACL reconstruction surgery. (hss.edu)
- When the fibro-osseous sheath is ruptured and deemed irreparable, reconstruction is accomplished utilizing a retinacular sling or free retinacular graft (see Techniques box). (dnahelix.com)
- If nonreconstructable, a sheath reconstruction with retinacular free graft or retinacular sling is employed. (dnahelix.com)
- A sheath reconstruction with retinacular free graft or retinacular sling is recommended. (dnahelix.com)

Athletes1
- Female athletes tend to land with their knees knocked inward. (massgeneralbrigham.org)
Flexion3
- We showed that grafts placed high within the femoral footprint and fixed at a lower flexion angle carried less force as the knee was flexed compared to grafts placed lower within the femoral footprint and fixed at a higher flexion angle, which could extend the useful life of the reconstruction. (hss.edu)
- It is performed with the knee in 30° of flexion, with the patient lying supine. (medscape.com)

Lateral extra-articular2
- Is the Lateral-Extra Articular Really Needed? (isakos.com)
- The aim of the study was to directly measure graft forces of an anterior cruciate ligament reconstruction (ACLR) and a lateral extra-articular tenodesis (LET) using the modified Lemaire technique in combined a. (springeropen.com)
Osteotomy2
- A large PTSA may increases risk of anterior cruciate ligament injury, so patients with more than 12 degrees of PTSA should be treated by preserving meniscus as much as possible during ACL reconstruction and combining with tibial osteotomy if necessary, which could effectively prevent risk of ligament re-injury. (bvsalud.org)
- These indications are not strict, as knee laxity, malalignment or cartilage defect can be addressed with anterior cruciate ligament (ACL) reconstruction, osteotomy or cartilage treatment at the same time as the meniscal substitution. (aspetar.com)
ACLR2
- Anterior cruciate ligament reconstruction (ACLR) is complicated by high failure rates in young active individuals. (nih.gov)
- Failure of ACLR is associated with limited activity, reduced quality of life, increased socioeconomic costs and higher rates of osteoarthritis (OA). (nih.gov)
Revision ACL Reconstruction2
- What is revision ACL reconstruction? (orthosportclinic.org)
- It may be recommended for selected cases of primary or revision ACL reconstruction. (orthosportclinic.org)
Laxity2
- Half of ACL injuries are associated with injuries to the meniscus, articular cartilage, other ligaments, excessive joint laxity or unfavorable bony anatomy. (orthosportclinic.org)
- Stress radiographs may be obtained to quantify knee laxity. (drrobertlaprademd.com)
Symptomatic1
- Both meniscal scaffolds (MS) and MAT are basically indicated in symptomatic patients after meniscectomy who usually present a knee with pain, swelling and reduction in function. (aspetar.com)
Injury2
- Posterior tibial slope angle (PTSA) is a risk factor for anterior cruciate ligament (ACL) injury and has attracted a lot of attention, but its mechanism of action and diagnosis are still not systematically studied in the field of sports medicine. (bvsalud.org)
- What is multi ligament injury? (orthosportclinic.org)
Meniscus3
- Although it has been recognized that the medial meniscus extrusion (MME) leads to progressive cartilage loss and osteoarthritis (OA), about 20% of cases with MME had minor symptoms and poor progression of knee. (springeropen.com)
- Common knee injuries may damage structures inside the joint including the meniscus, anterior cruciate ligament and joint surface cartilage. (orthosportclinic.org)
- Dr LaPrade performed a deep root repair to my meniscus, which saved me from a knee replacement at this time. (drrobertlaprademd.com)
Patellar1
- Recurrent patellar dislocation is treated with reconstruction of torn ligaments and realignment of the patellar tendon. (orthosportclinic.org)
Assessment2
- ACL reconstruction mostly fails due to poor initial assessment, poor surgery and poor biology. (orthosportclinic.org)
- Magnetic resonance imaging allows assessment of the complex anatomy of the knee and has excellent sensitivity and specificity for many injuries. (drrobertlaprademd.com)
Rupture2
- The bone landmark positioning method was used to position the femoral tunnel during the anatomical reconstruction surgery in patients with anterior cruciate ligament (ACL) rupture. (bvsalud.org)
- Surgical reconstruction is the current standard for ACL rupture treatment in active individuals. (springeropen.com)
Femur3
- The pivot shift test is performed by extending an ACL-deficient knee, which results in a small amount of anterior translation of the tibia in relation to the femur. (medscape.com)
- This occurs when the patella (knee cap) slips out from its groove in the femur. (orthosportclinic.org)
- The menisci are two knee structures, interposed between the articular surfaces of femur and tibia. (aspetar.com)
Varus2
- It is usually assumed that the severity of varus osteoarthritis (OA) of the knee is correlated with the axis deviation of the limb. (springeropen.com)
- This treatment requires a stable knee, normal alignment (not varus or valgus alignment) of the lower limb and a low grade of cartilage degeneration (less than grade III in Outerbridge scale). (aspetar.com)
Single-bundle1
- CONCLUSIONS: The bone tunnels were found to be distributed in and beyond the normal range using the bone landmark method to position the femoral tunnel in the single-bundle anatomical reconstruction of ACL, while the rate of good bone tunnel position was low. (bvsalud.org)
Meniscal4
- Arthroscopy is used to perform meniscal surgery, ACL/PCL reconstruction, treat infections, perform biopsy and manage cartilage damage. (orthosportclinic.org)
- Due to symptoms like pain, swelling and sudden knee blocks (especially in the case of displaced 'bucket handle' tears), it is quite impossible for those suffering a meniscal tear to perform any sport activity. (aspetar.com)
- Today the meniscal integrity is well-known to be crucial in the knee health 3,4 . (aspetar.com)
- In fact, many studies outline that even partial meniscal removal triggers the start of degenerative changes that can lead to the development of knee osteoarthritis 5 after 10 or more years. (aspetar.com)
Surgery4
- Patients undergoing knee surgery are at high risk for deep vein thrombosis (DVT), which is infrequent but potentially life-threatening. (springeropen.com)
- Arthroscopy is a keyhole surgery where a tiny telescope is inserted into the knee joint. (orthosportclinic.org)
- If your ACL reconstruction is painful or if the knee is unstable after surgery, a clinical and radiological analysis would ascertain the cause of failure. (orthosportclinic.org)
- Following a meniscectomy, some patients experience symptoms such as knee pain, swelling and reduced knee function for several months or years after the surgery. (aspetar.com)
Tears1
- Intra-articular reconstruction of the ACL has become the criterion standard for treating ACL tears. (medscape.com)

- The methods of surgical repair may be categorized into 3 groups: primary repair, extra-articular repair, and intra-articular repair. (medscape.com)
Torn1
- Ligament reconstruction is performed to replace torn ligaments for example- anterior cruciate ligament (ACL). (orthosportclinic.org)
Eligible1
- RESULTS: 84 eligible patients (84 knees) were finally included in this study. (bvsalud.org)
Arthritis1
- Various common types of arthritis include osteoarthritis, inflammatory arthritis (rheumatoid, seronegative) and secondary arthritis (post traumatic, post AVN). (orthosportclinic.org)
Joint2
- The Lysholm and IKDC scores, KT-1000 side-to-side difference, pivot shift test and Lachman test results of the knee joints were recorded, and then the differences in knee joint functions between the two groups were analyzed. (bvsalud.org)
- He has been successful in securing over 9 million dollars in peer reviewed and industry funded grants to build his pre-clinical and clinical research program focusing on complex ligament reconstruction and joint preservation. (isakos.com)
Clinical1
- Dr. Getgood's clinical practice focuses on complex soft tissue reconstruction of the knee. (isakos.com)
Pivot1
- This may prevent a pivot shift but has not been shown to decrease anterior tibial translation. (medscape.com)
Pain3
- ACL-MD usually presents in individuals over 40 years with sudden-onset knee pain after minimal trauma or as an incidental MRI finding. (bvsalud.org)
- We present a case of ACL-MD in a previously healthy adult in his early 20s who presented with 3-month recalcitrant dull left knee pain and limited range of motion after 'stepping funny' with slight twisting. (bvsalud.org)
- This leads to pain, swelling and locking of the knee. (orthosportclinic.org)
Main2
- The knee has 4 main ligaments - ACL, PCL, MCL and LCL. (orthosportclinic.org)
- The main role of the menisci is to weight bear, absorbing the pressure that otherwise would charge the soft articular cartilage, which is not structured to be loaded by the entire body-weight. (aspetar.com)
Ends1
- Because the ACL is intra-articular, the ligamentous ends are subjected to synovial fluid, which does not support ligamentous healing. (medscape.com)
Poor1
- Arthroscopy may also be considered for persons who are poor candidates for reconstruction but have a mechanical block to range of motion. (medscape.com)
Damage1
- This is caused by an altered biomechanical environment established after the removal that will lead to damage of the articular cartilage and, eventually, to osteoarthritis. (aspetar.com)
