BACKGROUND Objective measures to quantitate the amount of lateral compartment opening for patients with lateral and posterolateral knee injuries have not been well documented. The purpose of the present study was to measure lateral compartment opening secondary to applied varus stresses following posterolateral corner structure sectioning and to develop radiographic guidelines to quantify the a...

We report a case of abnormal meniscal-like anterior cruciate ligament (ACL), inserting at the 9 o’clock position just beside the cartilage of the lateral femoral condyle, in a stable knee associated with osteochondritis dissecans (OCD) of the medial femoral condyle.

We report two new radiographic projections for evaluating avulsion fractures at the lateral malleolus. We used seven freshly amputated legs with simulated avulsion fractures and radiopaque markers to assess their value. The projections allow accurate assessment of the displacement of fragments without superimposition, and also show whether they affect the anterior talofibular or the calcaneofib...

Case 1 description Buddy is an active 33-year-old man who presents to the emergency department (ED) complaining of pain in his left ankle and foot after falling while back-country skiing 3 days ago. The fall involved a moderatespeed slide down a steep chute and rotational release of the left leg from the ski binding. Buddy experienced immediate pain to the lateral malleolar region. Immediately ...

PURPOSE This study was undertaken to evaluate the histologic and ultrastructural characteristics of the patellar tendon 10 years after reharvesting its central third. HYPOTHESIS In the long term, after its central third is reharvested, the patellar tendon does not regain a normal histological and ultrastructural appearance. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS Tw...

INTRODUCTION Knee arthroscopy knee is gold standard in diagnosis and simultaneous treatment of knee disorders. But most patients undergo magnetic resonance imaging (MRI) before arthroscopy, although MRI results are not always consistent with arthroscopic findings. This raises the question in which suspected diagnoses MRI really has influence on diagnosis and consecutive surgical therapy. MATE...

PURPOSE To systematically review and compare biomechanical results of lateral extra-articular tenodesis (LET) procedures. METHODS A systematic review was performed using the PubMed, Medline, Embase, and Cochrane databases. The search terms included the following: extraarticular, anterolateral, iliotibial, tenodesis, plasty, augmentation, procedure, reconstruction, technique, biomechanics, kin...

PURPOSE To establish the sensitivity and specificity of indirect signs at magnetic resonance (MR) imaging of anterior cruciate ligament (ACL) tear. MATERIALS AND METHODS MR images of the knees of 89 consecutive patients (54 with torn and 35 with normal ACLs) were reviewed. RESULTS The indirect signs were as follows (first percentage is sensitivity; the second, specificity): angle between la...

The debate around extra-articular augmentation (EA) of anterior cruciate ligament (ACL) reconstruction continues to provide a rich source research articles that we ultimately hope will improve patient outcomes. When combined with ACL reconstruction, anterolateral or lateral tenodesis procedures reduce graft failure and persistent rotatory laxity. An important metric outcome is return play (RTP)...
