人工膝関節単顆置換術後の農業とスポーツ活動－TKAと比較して－

抄録

Objective: Few studies have been published about assessing agricultural and sporting activity after unicompartmental knee arthroplasty (UKA) and/or total knee arthroplasty (TKA). In this study, agricultural and sports participation were analyzed using a self-administered questionnaire in 100 patients who had undergone UKA.
Methods: A total of 100 patients were enrolled in this study, comprising 70 women and 30 men with a mean age of 75.7 years (range, 58-86 years) with a mean of 4.9 (range, 1-18 years). All 100 patients were given a self-administered questionnaire about their agricultural and sporting activities after UKA was performed. These results were compared to those after TKA.
Results: Thirty-eight patients engaged in agricultural activities before surgery, and 31 of 38 patients continued agricultural activities after UKA. 79.5% of patients returned to agricultural activities after UKA. Forty-four of 51 patients continued these after TKA, and the return to agriculture rate was 86.2%. Thirty-two of 38 patients participated in sporting activities after UKA. Fifteen of 30 patients participated in sporting activities prior to surgery, and only 40.0% of patients returned to sports after TKA. However, in the UKA, 73.7% of patients returned to sports after surgery.
Conclusion: With respect to agricultural activities, there was no significant difference between the UKA and TKA group. Patients had a significantly greater return to sporting activities after UKA than patients who had undergone TKA.
