Foreign body reactions may occur in patients who receive bioabsorbable implants during orthopedic surgery for fractures and ligament repair. The authors describe a 34-year-old man who presented with a palpable tender mass on the lateral aspect of the left knee of 1 month's duration. He underwent posterior cruciate ligament and posterolateral corner reconstruction 3 years earlier. Physical exami...

BACKGROUND Injury to the lateral capsular tissues of the knee may accompany rupture of the anterior cruciate ligament (ACL). A distinct lateral structure, the anterolateral ligament, has been identified, and reconstruction strategies for this tissue in combination with ACL reconstruction have been proposed. However, the biomechanical function of the anterolateral ligament is not well understood...

BACKGROUND The current "gold standard'' for treatment of chronic lateral ankle instability is the Broström-Gould procedure. Most authors recommend this type of operation even after an arthroscopic inspection of the joint. We review our results with an arthroscopic method of lateral ankle ligament repair. MATERIALS AND METHODS A method of arthroscopic lateral ligament repair with an anchor pla...

BACKGROUND Isolated radial head dislocation is a rare injury with an unclear pathomechanism, and the treatment is controversial. The purpose of the present study was to investigate the biomechanical contributions of the annular ligament, quadrate ligament, interosseous membrane, and annular ligament reconstructions to proximal radioulnar joint stability. METHODS Five fresh frozen cadaveric up...

BACKGROUND Numerous biomechanical studies of the lateral ankle ligaments have been reported; however, the isolated function of the calcaneofibular ligament has not been clarified. We hypothesize that the calcaneofibular ligament would stabilize the ankle joint complex under multidirectional loading, and that the in situ force in the calcaneofibular ligament would change in each flexed position....

The cranial cruciate ligament (CrCL) runs from the caudomedial part of the lateral condyle of the femur diagonally across the intercondylar fossa to the cranial intercondyloid area of the tibia. The caudal cruciate ligament (CaCL) runs from the lateral surface of the medial femoral condyle caudodistally to the lateral edge of the popliteal notch of the tibia. The cruciate ligaments consist of t...

PURPOSE To review the outcome of the modified Brostrom-Evans-Gould technique in patients with chronic lateral ankle ligament instability. METHODS Between August 2003 and June 2005, 20 men aged 19 to 35 (mean, 23) years with chronic lateral instability affecting 21 ankles, underwent the modified Brostrom-Evans-Gould technique by a single surgeon. The mean follow-up period was 12 (range, 6-20) ...

The lateral collateral ligament (LCL) complex of the elbow plays a crucial role in the stability of the elbow joint, especially to varus loads. Deficiency of particularly the lateral ulnar collateral component of the LCL can lead to chronic posterolateral rotatory instability, which can be functionally debilitating and can lead to a rapid onset of early degenerative arthritis. Commonly, in the ...

A 58-year-old male patient who had developed left knee pain with a history of trauma was referred to our hospital. Physical examination and further examination by magnetic resonance imaging revealed results that closely resemble a horizontal tear of the lateral meniscus and a tear of the medial meniscus. Arthroscopically, we found a cord-like structure originating from the posterior 1/3 portion...
