Giant cell synovitis associated with failed polyethylene patellar replacements.

Destroyed patellar articular surfaces were replaced with a high molecular weight polyethylene prosthesis in two patients. The patellofemoral articulation of the femur consisted of eburnated bone in one case and degenerative cartilage in the other. Both operations failed within one year because of a giant cell synovitis caused by a high volume (0.2 cc) of fine polyethylene (1-100 mu) wear particles. Ultra high molecular weight polyethylene should not be used as a prosthetic bearing surface to articulate against cortical, cancellous or eburnated bone or against degenerative articular cartilage in a major joint.

Osteotomy as an alternative to total hip replacement in young adults.

The young (under 50) patient with symptomatic osteoarthrosis of the hip from congenital hip dysplasia presents a difficult therapeutic problem. Although total hip replacement can be successful in such cases, the uncertaintly of a long-term result makes an alternative treatment attractive. A series of 15 patients with 17 involved hips were subjected to a carefully planned and executed valgus osteotomy combined with a selective muscle lengthening about the hip. Five years or more after this procedure 14 of the 17 hips of these patients were pain free. The other three hips caused mild pain only after exertion. No patient at final follow-up required external support. Sixteen of the 17 hips showed significant radiological regression of the osteoarthrosis.
