PURPOSE The purpose of this study was to evaluate the relative importance of the different static stabilizers of the posterolateral corner of the knee in cadavers. METHODS Tests were performed with the application of a varus and external rotation force to the knee in extension at 30 and 60 degrees of flexion using 10 cadaver knees. The forces were applied initially to an intact knee and then ...

ateral stability of the elbow depends on the integrity of the lateral collateral ligament and secondary softtissue restraints. Posterolateral rotatory subluxation of the elbow has been recognized in association with elbow trauma, surgery for epicondylitis, and congenital cubitus varus deformity. While abnormal signal changes on magnetic resonance imaging have been shown to include the lateral c...

BACKGROUND Various surgical techniques to treat posterolateral knee instability have been described. To date, the recommended treatment is an anatomic form of reconstruction in which the 3 key structures of the posterolateral corner (PLC) are addressed: the popliteofibular ligament, the popliteus tendon, and the lateral collateral ligament. PURPOSE/HYPOTHESIS The purpose of this study was to ...

The authors report a case of a patient that was submitted to a surgery of reconstruction of anterior cruciate ligament and collateral medial ligament repair of the left knee that complicated to a compartment syndrome.

BACKGROUND Currently, several graft options have been described for reconstruction of the medial ulnar collateral ligament of the elbow. Palmaris longus, gracilis, plantaris, toe extensor, and even Achilles tendon autografts have been well documented. To our knowledge, no study has investigated the clinical outcomes following the use of allograft tendon for primary medial ulnar collateral ligam...

The development of an in vivo animal model of posterolateral knee instability is desired for devising effective interventions for this injury. Sequential sectioning of the popliteus tendon, lateral collateral ligament, and lateral capsule was done in cadaveric goat knees to create knee joint instability, followed by in vivo studies (Studies 1 and 2) of 7 and 3 months duration, respectively. In ...

The calcification of knee ligaments is a finding noted only in a handful of case reports. The finding of an anterior cruciate ligament calcification has been reported once in the literature. Comparable studies involving the posterior cruciate ligament, medial collateral ligament and an ossicle within the anterior cruciate ligament are likewise discussed in reports of symptomatic patients. We re...

Femoral tunnel intersection in combined anterior cruciate ligament and posterolateral corner reconstruction has been reported to be high. The purpose of this study was to examine the risk of intersection between an anatomic femoral anterior cruciate ligament tunnel created with a retrograde reaming device and femoral lateral collateral ligament reconstruction tunnels of varying trajectory in a ...

CONTEXT The ulnar collateral ligament of the elbow (UCL) is frequently injured in throwing athletes, most commonly baseball pitchers. The ligament is reconstructed through bone tunnels using palmaris longus or gracilis autograft. RESULTS This study highlights the following technique for UCL reconstruction in over 2000 athletes.(2) CONCLUSION When conservative management fails, ligament reco...

Discussion Differential diagnoses included chip fracture of the patella, femur or tibia, or an avulsion fracture of a ligament insertion. Based on location and cranial-caudal instability, avulsion of the origin of the cranial cruciate ligament was considered most likely, with concurrent lateral collateral ligament sprain, and potential further intra-articular damage. Exploratory surgery of the ...
