We report a case of a 34-year-old man who had an acute gouty attack with tophi around the accessory bone of the bipartite patella with intra-osseous lesions. As the symptoms did not respond to conservative treatments, the patient was treated surgically. Arthroscopy revealed urate crystals surrounded by inflammatory synovitis on the surface of the bipartite patella. Arthrotomy exposed the abunda...

BACKGROUND This diagnostic study was performed to determine the correlation between anterior knee pain and chondromalacia patellae and to define the reliability of magnetic resonance imaging for the diagnosis of chondromalacia patellae. METHODS Fifty-six young adults (median age, 19.5 years) with anterior knee pain had magnetic resonance imaging of the knee followed by arthroscopy. The patell...

Congenital dislocation of the knee (CDK) is a very rare condition. Here we report our strategy and results in treatment of three children with CDK. All three patients were treated with conservative method, and only one had underwent a surgical procedure on one knee. Of the remaining, we recorded a good outcome with conservative treatment in three knees, while two had poorer outcome as a result ...

The patella plays an important role in the knee joint extension, and a patella fracture requires surgical treatment when it is accompanied by displacement of bone fragments and a joint surface gap. In patella fractures, there is disruption of the soft tissue structures that support the knee extension mechanism. We use a method of percutaneous cerclage wiring to fix the patella and include the p...

A series of7S patients with established chondromalacia patellae is presented. All had a lateral release procedure carried out after failure of conservative treatment. The results are discussed in relation to the findings at operation. In the early stages of chondromalacia, release of the lateral retmaculum was successful in relieving the symptoms for a year or more; review at three years showed...

Background Patellar height has long been considered a risk factor for patellofemoral instability. However, recent pediatric literature demonstrated a reduction in patellar height measurements following medial patellofemoral ligament (MPFL) reconstruction. Purpose To assess the mean change in patellar height and the percentage of skeletally mature patients with patellar height ratios reduced t...

BACKGROUND Recurrent dislocation of the patella in patients with below knee amputation is a known entity. Abnormally high-riding patella (patella alta) and medial patellofemoral ligament insufficiency in these patients predisposes them to patellar instability. The established treatment of this problem is surgical realignment. CASE PRESENTATION A 25 year old male patient with bilateral below k...
