Abstract
A study of the long-term results of arthroplasty of the elbow and the knee using J-K membrane has been made.
37 cases of arthroplasty of the elbow were evaluated clinically and roentgenographically an average of 14 years after operation. These cases had an average range of motion of 61 degrees with good stability and without pain. An average range of motion is 76 degrees in the group following rheumatoid arthritis, 65 degrees in the group following trauma and 37 degrees in the group following infectious arthritis.
50 cases of arthroplasty of the knee were evaluated an average of 16 years after operation. An range of motion is 72 degrees in the group following rheumatoid arthritis, 70 degrees in the group following trauma and 47 degrees in the group following infectious arthritis.
It can be concluded that arthroplasty of the elbow and the knee using J-K membrane, properly performed in selected cases, offers on useful range of motion with good stability and strength.
