The purpose of this study was to investigate sports activities and functional abilities in patients following total knee arthroplasty (TKA). It was hypothesized that patients who had undergone TKA would return to a higher activity level as that experienced preoperatively.
Two hundred patients were included in this prospective single-cohort study. All the patients completed subjective questionnaires (Tegner Activity Level, Oxford Knee Score, Visual Analog Scale for pain) prior to surgery as well as at 6, 12, and 24 months postoperatively. Additionally, sports behaviour was evaluated. Sports frequency was divided into four categories: more than 5 times a week, 2-3 times a week, occasionally, and no sports activities. Additionally, the patients were asked to state their three favourite summer and winter sports.
All patient-reported outcome scores improved significantly over time (p ≤ 0.005). The Tegner Activity Level increased significantly from the preoperative state to 24 months postsurgery (p = 0.005). Six months after surgery, 43% of the patients returned to the same and 35% to a higher Tegner Activity Level than prior to surgery. Gender-related differences were observed for the Tegner Activity Level showing a higher activity level for the male than for the female patients. Overall, 24 months postsurgery 83% of the patients practiced sports in comparison with 79% prior to surgery.
Following TKA, the patients were able to increase sports performance, while pain was reduced. Therefore, patients who want to continue their desired sports may safely consider TKA.

本研究旨在探讨全膝关节置换术（TKA）后患者的运动活动和功能能力。假设 TKA 患者的活动水平将恢复到术前水平。
本前瞻性单队列研究纳入了 200 名患者。所有患者在术前以及术后 6、12 和 24 个月时均完成了主观问卷（Tegner 活动水平、牛津膝关节评分、视觉模拟评分）。此外，还评估了运动行为。运动频率分为四个类别：每周 5 次以上、每周 2-3 次、偶尔和不参加运动。此外，患者还被要求说出他们最喜欢的三种夏季和冬季运动。
所有患者报告的结果评分均随时间显著改善（p≤0.005）。Tegner 活动水平从术前状态显著增加到术后 24 个月（p=0.005）。术后 6 个月，43%的患者恢复到与术前相同的 Tegner 活动水平，35%的患者恢复到更高的 Tegner 活动水平。Tegner 活动水平存在性别差异，男性的活动水平高于女性。总体而言，术后 24 个月，83%的患者参加运动，而术前为 79%。
TKA 后，患者能够提高运动表现，同时减轻疼痛。因此，想要继续进行期望运动的患者可以安全地考虑 TKA。
