ABSTRACT
BACKGROUND: A growing number of physically active patients undergoing total knee replacement (TKR) desires to resume their preoperative activity levels and to be able to engage in sports after surgery. The purpose of this study was to assess the sporting and physical activities of patients who had undergone TKR. It was hypothesized that the majority of patients treated by TKR would have been able to return to amateur sports and recreational activity .
METHODS: Ninety-seven patients who underwent TKR between 2014 and 2016, were retrospectively reviewed. Mean age was 70.1 years (range 64-83). Average follow-up time was 4.2 years (SD: 1.7). Assessment included Knee Osteoarthritis Outcome Score (KOOS), International Knee Documentation Committee (IKDC), and Tegner activity level. Sporting and physical activities of all patients were reported. Wilcoxon’s signed ranks test was used for comparison between pre-operative and follow-up data. Significance was set at p < 0.05.
RESULTS: Both KOOS score and IKDC significantly improved after surgery (p < 0.001). No statistically significant differences were reported concerning Tegner activity level before and after surgery (p = n.s.). After surgery, a total number of 52 patients (53.6%) successfully returned to sporting and recreational activities, such as cycling, hiking, dancing and swimming. A return to activity rate of 81% of patients practicing sport before surgery was reported.
CONCLUSIONS: TKR provides a high rate of return to sport postoperatively and confirms improved subjective results and reduced pain compared to preoperative status. However, most patients returned to low-impact activities, while a significant decrease was reported for mid- and high-impact sports.
