The aim of this study was to determine which type of knee arthroplasty is easier to forget by comparing levels of joint awareness evaluated with the Forgotten Joint Score (FJS-12) after unicondylar versus total knee arthroplasty.
Patients who underwent either unicondylar or total knee arthroplasty due to primary gonarthrosis were retrospectively identified and then divided into 2 groups: the TKA group (218 patients; mean age = 68.93 ± 7.14 years) and the UKA group (131 patients; mean age = 60.39 ± 7.03 years). The status of joint awareness after knee replacement surgery was assessed using the Turkish version of the FJS-12 at the final follow-up by telephone interview. Also, The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and The EuroQol five-dimensional (EQ-5D) scores were obtained to assess the clinical status of the patients.
The mean follow-up was 2.8 years (range = 24-49 months) in the TKA group and 3.2 years (range = 24-50 months) in the UKA group. The FJS-12 was significantly higher in the UKA group (73.60 ± 9.95) than in the TKA group (64.88 ± 9.47) (P = .001). The WOMAC score was significantly better in the UKA group (81.39 ± 9.84) than in the TKA group (74.92 ± 9.99) (P = .001). No significant difference in EQ-5D existed between the groups (0.76 ± 0.14 for the TKA group, 0.79 ± 0.17 for the UKA group; P = .441). In terms of gender, the FJS-12 showed no differences between the groups; however, more favorable scores were recorded in younger patients with UKA.
The results of this study have demonstrated that UKA may be better than TKA in terms of the patient perception of pain, stiffness, and physical functioning.

本研究旨在通过比较单髁膝关节置换术（UKA）和全膝关节置换术（TKA）后关节意识评分（FJS-12）来确定哪种类型的膝关节置换术更容易被遗忘。
回顾性地确定了因原发性膝骨关节炎而接受 UKA 或 TKA 的患者，并将其分为 2 组：TKA 组（218 例；平均年龄=68.93±7.14 岁）和 UKA 组（131 例；平均年龄=60.39±7.03 岁）。通过电话访谈在最终随访时使用土耳其语版 FJS-12 评估膝关节置换术后关节意识状况。还获得了西安大略和麦克马斯特大学骨关节炎指数（WOMAC）和欧洲五维健康量表（EQ-5D）评分，以评估患者的临床状况。
TKA 组的平均随访时间为 2.8 年（范围=24-49 个月），UKA 组为 3.2 年（范围=24-50 个月）。FJS-12 在 UKA 组（73.60±9.95）显著高于 TKA 组（64.88±9.47）（P=.001）。WOMAC 评分在 UKA 组（81.39±9.84）显著优于 TKA 组（74.92±9.99）（P=.001）。两组之间 EQ-5D 无显著差异（TKA 组为 0.76±0.14，UKA 组为 0.79±0.17；P=.441）。就性别而言，FJS-12 在两组之间无差异；然而，在接受 UKA 的年轻患者中记录到了更有利的评分。
本研究结果表明，在患者对疼痛、僵硬和身体功能的感知方面，UKA 可能优于 TKA。
