The purpose of our study was to evaluate clinical outcomes and return to sports after medial unicompartmental knee arthroplasty (UKA) in middle-aged active patients with concomitant patella-femoral joint (PFJ) osteoarthritis at time of surgery.
One-hundred and fifty-one patients who underwent medial fixed-bearing cemented UKA, between 2012 and 2015, for medial unicompartmental osteoarthritis of the knee, were retrospectively reviewed with a minimum 5-year follow-up. The mean age at surgery was 54.3 years (range 47 to 60 years). Radiological evaluation of patella-femoral joint (PFJ) osteoarthritis was performed according to Sperner classification to select a control-group (< grade III) and case-group (≥ grade III). The visual analog scale (VAS) for pain and Knee Society score (KSS) was used to evaluate preoperative and final outcomes. Physical activity level before and after the surgery was assessed by the use of UCLA score.
One-hundred and thirty-seven patients (89 males and 48 females) were available at last follow-up. The mean follow-up was 6.2 years (range 5.2 to 7.5 years). At last follow-up improvements of VAS and KSS scores revealed not significant correlation with PFJ osteoarthritis. The majority of patients (87.7%) returned to their sports activity after UKA surgery.
Improved quality of life and sports activity level resulted in middle-aged, active patients after UKAs. PFJ osteoarthritis showed no significant correlation with poorer outcomes at 5-year follow-up.

我们研究的目的是评估中年活跃患者在膝关节内侧单间室骨关节炎（UKA）手术时合并髌股关节（PFJ）骨关节炎的临床结果和重返运动情况。
回顾性分析了 2012 年至 2015 年间接受内侧固定轴承水泥固定 UKA 治疗的 151 例内侧单间室骨关节炎患者，随访时间至少为 5 年。手术时的平均年龄为 54.3 岁（范围为 47 至 60 岁）。根据 Sperner 分类对髌股关节（PFJ）骨关节炎进行放射学评估，以选择对照组（<III 级）和病例组（≥III 级）。使用视觉模拟评分（VAS）评估疼痛和膝关节协会评分（KSS）来评估术前和最终结果。使用 UCLA 评分评估手术前后的身体活动水平。
137 例患者（89 名男性和 48 名女性）在最后一次随访时可用。平均随访时间为 6.2 年（范围为 5.2 至 7.5 年）。在最后一次随访时，VAS 和 KSS 评分的改善与 PFJ 骨关节炎无显著相关性。大多数患者（87.7%）在 UKA 手术后恢复了运动活动。
改善生活质量和运动水平是中年活跃患者接受 UKA 手术后的结果。PFJ 骨关节炎在 5 年随访时与较差的结果无显著相关性。
III 级，多中心回顾性队列研究。
