Single compartment modular knee replacements produced good or excellent three-year follow-up results in a success rate of 92 per cent. Contracture, thrombophlebitis, infections and other complications are infrequent.
Hemiarthroplasty was performed in 10 patients with rheumatoid arthritis of the shoulder joint. A humeral head prosthesis was inserted to replace the articular surface of the humeral head in 12 shoulders. Marked relief of pain and improved function in long term follow-up examinations were noted in the majority of the patients. The indication for shoulder hemiarthroplasty is severe pain and chronic rheumatoid disease.
Candida albicans arthritis is unusual but does occur perhaps more often than recognized. The most common site of infection is the knee joint in the adult and can be related to contamination of the joint at the time of intraarticular injection of corticosteroids.
Severe pain in the groin following total hip replacement may occur suddenly without any trauma. Roentgenograms can be misleading when a radiolucent line is noted about the acetabular component which suggests loosening but in fact may be a stress fracture of the pubis.
Ten cases of loosening of the femoral component following a Charnley total hip replacement were noted in a series of 160 patients. In 3 patients, the femoral component bent without fracturing. All of the patients were overweight. Loosening occurred despite the fact that the femoral component was in a valgus position in 9 of the 10 cases. Collapse of the cancellous bone in the region of the calcar may be a manifestation of the stress of excessive body weight upon the femoral component.
