Abstract

In this study, patients who played sports after undergoing a total knee arthroplasty (TKA) were functionally analyzed and their degree of satisfaction was surveyed. The study group consisted of seven men and four women (out of a group of 89 total knee arthroplasties). They were evaluated by the Tegner [1] activity score and the Japanese Orthopaedic Association (JOA) score [2]. The mean age of the patients was 68 years (range: 47 to 76) at surgery and the mean follow-up period was 26.4 months (range: 11 to 60). Wright Advantim uncemented knee prostheses with a stem and posterior stabilizer or Wright Advance uncemented knee systems (Wright Medical, USA) were used. All operations were performed using a medial subvastus approach by the senior author (TY). The mean preoperative JOA score was 67.3 and it improved to 87.3 at follow-up. The mean Tegner score improved from 1.5 to 4 points after the operation in those patients who returned to sports. At follow-up, none of the patients demonstrated polyethylene wear, showed signs of loosening or required revision surgery. Once strength, mobility, and coordination recovered, patients were successfully allowed to return to low-impact activity such as downhill skiing, jogging, hiking, and mountaineering. It is too early to determine the effect of these increased activities on polyethylene wear and loosening.
