Objective:

To analyze the relation between the radiological and functional results and satisfaction of the knee prosthesis.

Material and Methods:

In this study, knee prosthesis applied to 43 patients’ 76 knees were retrospectively evaluated. As a radiologic parameter; anatomical alignment, and as a functional measurement; range of motion was evaluated. Visual analogue scale (VAS) was measured as a pain score. The relation of functional and radiological measurements with VAS scores was analyzed. All the patients were re-evaluated with Oxford knee score.

Results:

Study group included 37 women and 6 men with a mean age of 63 (26-76). A total number of 76 knees (33 bilateral, 10 unilateral) were evaluated. Mean follow up time was 16.25 months (2-29 months). In the last evaluation; according to the preoperative evaluation, varus deformity improved, functional improvement could not be gained and VAS decreased, in 23 knees. In 21 knees, no radiological and functional improvement could be gained, VAS decreased. In 13 knees, no radiological difference was obtained, functions got worse, VAS decreased. In 3 knees, no radiological difference was obtained, functions were better, VAS decreased. Three knees were radiologically worse, without any change in functions, VAS decreased. In 2 knees, radiological and functional results improved, VAS decreased. In 2 knees, although there was postoperative infection, VAS decreased. In only 3 knees, radiological and functional results were worse and VAS score did not change. Mean Oxford knee score was 9.7.

Conclusions:

Although radiological and functional results are not so good, application of the knee prosthesis decreases the patients’ pain and increases the patients’ satisfaction.
