Abstract:
[Objective] To analyze the cases performed by unicompartmental knee arthroplasty in order to assess the early outcome,and to discuss the indications and the key points of surgical technique.[Methods]Under the principle of "slight undercorrection",15 patients were performed by unicompartmental knee arthoplasty with the technique of limited medial release if necessary.The HSS score,the fomeral tibial angle and the maxima degree of flexion and extension measured preoperatively and in the latest follow-up were analyzed by SPSS 13.0 with the method of paired t test.Meanwhile the angle of the posterior slope of the tibial implants was measured.[Results]Postoperatively the HSS score,the fomeral tibial angle and the maxima degree of flexion and extension were improved significantly in the latest follow-up,and the average angle of the posterior slope of the tibial implants was 4.2 degrees.[Conclusion]Unicompartmental knee arthroplasty has a satisfing early outcome.And it is very important to carry out the indications strictly.With the surgical technique of limited medial release,the flexional contracture could also be improved significantly.
