Knee osteoarthritis (KOA) is common in middle-aged and elderly individuals, leading to progressive cartilage degeneration, pain, and impaired mobility.
To investigate the effect of unicompartmental knee arthroplasty (UKA) on swelling and pain of affected limbs and functional rehabilitation in patients with KOA.
One hundred KOA patients treated in our hospital from August 2022 to December 2024 were selected and divided into a test group (n = 48) receiving UKA and a matched group (n = 52) receiving total knee arthroplasty (TKA). The ROM, HKA, circumferences 10 cm below and above the midpoint of the patella, HSS score, VAS score, and the European Cancer Treatment Research Organization Quality of Life Scale (EORTC QLQ-C30) score were compared before and after operation.
At 6 months postoperatively, the HSS score and ROM were significantly higher in the test group (92.21 ± 7.10 points and 103.30 ± 5.50°) than in the matched group (P < 0.05), while HKA (2.33 ± 0.82°) was significantly lower (P < 0.05). On the 7th postoperative day, circumferences 10 cm below and above the patella were significantly reduced in the test group compared to the matched group (P < 0.05). The VAS score in the test group was lower (1.02 ± 0.34 vs. 3.20 ± 0.92, P < 0.05). The EORTC QLQ-C30 score was significantly higher in the test group (92.10 ± 7.82 vs. 81.18 ± 8.40, P < 0.05), indicating better quality of life. Complication rates did not differ significantly between groups (P > 0.05).
Compared with total knee arthroplasty, UKA demonstrates better short-term outcomes in relieving pain, reducing swelling, and promoting functional recovery in patients with knee osteoarthritis. These findings support UKA as an effective option for appropriately selected patients. However, the study is limited by its single-center design and short-term follow-up.
膝关节骨关节炎（KOA）在中老年人中很常见，会导致软骨进行性退变、疼痛和活动能力受损。
探讨单髁膝关节置换术（UKA）对KOA患者患侧肢体肿胀、疼痛及功能康复的影响。
选取2022年8月至2024年12月在我院接受治疗的100例KOA患者，分为接受UKA的试验组（n = 48）和接受全膝关节置换术（TKA）的匹配组（n = 52）。比较手术前后的关节活动度（ROM）、髋膝角（HKA）、髌骨中点上下10 cm处的周长、膝关节协会评分（HSS评分）、视觉模拟评分法（VAS评分）以及欧洲癌症治疗研究组织生活质量量表（EORTC QLQ-C30）评分。
术后6个月，试验组的HSS评分和ROM（分别为92.21±7.10分和103.30±5.50°）显著高于匹配组（P < 0.05），而HKA（2.33±0.82°）显著低于匹配组（P < 0.05）。术后第7天，试验组髌骨上下10 cm处的周长较匹配组显著减小（P < 0.05）。试验组的VAS评分更低（1.02±0.34 vs. 3.20±0.92，P < 0.05）。试验组的EORTC QLQ-C30评分显著更高（92.10±7.82 vs. 81.18±8.40，P < 0.05），表明生活质量更好。两组并发症发生率差异无统计学意义（P > 0.05）。
与全膝关节置换术相比，UKA在缓解膝关节骨关节炎患者疼痛、减轻肿胀和促进功能恢复方面显示出更好的短期效果。这些结果支持UKA作为适合患者的有效选择。然而，本研究受单中心设计和短期随访的限制。
