Preliminary experience with the geomedic total knee replacement

This paper reports preliminary experience with the Geomedic total knee replacement prosthesis. Forty-five prostheses were inserted into the severely damaged knees of 38 patients. Forty-one knees (35 rheumatoid, 6 osteoarthrotic) in 34 patients were available for review by an independent observer, a mean of 18 months (range 4--38 months) post-operatively. The assessment concentrated upon changes in function, pain relief and patient satisfaction, but objective parameters of range of movement and stability were also recorded. There were 23 excellent results, 15 good, 1 fair, and 2 poor. Thus, 93% of operations resulted in definite improvement. Complications occurred following 16 operations, but were mostly minor. One prosthesis dislocated, and there was one case of late infection which was treated successfully.
