A Case of a Extrasynovial Ossifying Chondrolipoangioma in the Infrapatellar Fat Pad: Advanced Stage of Hoffa's Disease

Hoffa's disease refers to inflammation, subsequent hypertrophy and impingement of the infrapatellar fat pad, and this is all triggered by acute trauma or repetitive microtrauma. Patients with Hoffa's disease manifest with anterior knee pain and functional impairment. The chronic impingement of the infrapatellar fat pad, which contains many progenitor cells, may promote fibrocartilaginous formation and osteochondral metaplasia of adipose tissue, so osteochondroma is sometimes found in patients with advanced Hoffa's disease. We report here on an ossifying chondrolipoangioma as an advanced form of Hoffa disease that occurred in the infrapatellar fat pad.

Treatment for the Supracondylar Fractures of the Distal Humerus with Cannulated Screw

PURPOSE: To evaluate the results of the treatment of the supracondylar fractures of the humerus according to the fixation methods with cannulated screw. MATERIALS AND METHODS: Eight patients, aged 49 to 82 years (average, 65 years), were reviewed after a mean follow-up of 16 months (range, 12~24 months). According to AO classification all fractures were classified as type A2 (simple transverse supracondylar fracture). All patients underwent closed reduction. Percutaneous fixation with cannulated screws was performed in 8 patients. Three of 8 patients had associated medical problems and one patient had distal radius fracture. The functional results were assessed by the Mayo Elbow Performance Score. RESULTS: Mean operation time was 59 minutes (45~75) and all the patients with cannulated screw fixation had bony union and were able to early ROM exercise. Mean ranges of motion was 5~120 degrees with excellent functional results. Functional evaluation of elbow joint by Mayo method showed mean value of 88 (75~95). CONCLUSION: The cannulated screw fixation of supracondylar fracture of humerus, especially in the elderly aged group with medical disease had excellent functional results (rigid fixation & early ROM exercise) due to shortening of surgery time and anesthesic time, combined with decreased technical difficulties of the surgical procedure
