Abstract

Summary Total joint replacement is a valuable new procedure in orthopedic surgery. The low friction arthroplasty of Charnley and the Charnley- Muller prosthesis are discussed. Sixty-six operations performed at the University of Illinois Hospital between June 1968 and January 1970 are evaluated. Satisfactory results in relief of pain and ability to walk were obtained in over 90 per cent of the patients. Wound infection was a major disaster, an incidence of 6.6 per cent. Ten patients required reoperations, three for replacement of a loose prosthesis, two for rewiring of the trochanter, three for removal of trochanteric wires, and two for removal of the prostheses after wound infection. The indications and contraindications are discussed as well as the relative merits of both techniques. Proper attention to the indication guidelines and to technical details are essential to insure good results.
