To compare the clinical efficacy of total knee arthroplasty (TKA) and unicondylar knee arthroplasty (UKA) in the treatment of knee osteoarthritis (KOA).
A retrospective analysis was conducted on 30 patients admitted to the Department of Orthopaedics of Yijishan Hospital from 2020 to 2021. The patients were divided into UKA group ( = 15) and TKA group (control, = 15). The intraoperative situation and postoperative clinical indicators of patients in the two groups were collected and compared, such as operation time, intraoperative blood loss, length of hospital stay, postoperative complications, and postoperative functional recovery. Postoperative functional recovery was investigated by the visual analogue pain scale (VAS), knee score scale (HSS), and knee range of motion (ROM) scores 5 days after surgery.
Perioperative indexes in the UKA group were significantly lower than those in the TKA group, including operation time, intraoperative blood loss, first time going to the ground, and length of hospital stay. VAS, HSS, and ROM scores in the two groups were significantly improved after surgery compared with those before surgery. However, ROM scores in the UKA group were significantly better than in the TKA group. In terms of early postoperative complications, there was one case of venous thrombosis of lower limbs in the UKA group, while in the TKA group there was one case of delayed wound healing due to diabetes, and one case of deep infection.
Both UKA and TKA are very successful options for the treatment of KOA, but the use of UKA can promote the recovery of postoperative knee function, reduce postoperative complications, and achieve more satisfactory than expected results.
比较全膝关节置换术（TKA）和单髁膝关节置换术（UKA）治疗膝骨关节炎（KOA）的临床疗效。
回顾性分析 2020 年至 2021 年期间在弋矶山医院骨科就诊的 30 例患者。患者分为 UKA 组（n=15）和 TKA 组（对照组，n=15）。收集并比较两组患者的术中情况和术后临床指标，如手术时间、术中出血量、住院时间、术后并发症和术后功能恢复。术后 5 天，采用视觉模拟疼痛量表（VAS）、膝关节评分量表（HSS）和膝关节活动度（ROM）评分评估术后功能恢复情况。
UKA 组围手术期指标明显低于 TKA 组，包括手术时间、术中出血量、首次下地时间和住院时间。两组术后 VAS、HSS 和 ROM 评分均较术前明显改善，但 UKA 组 ROM 评分明显优于 TKA 组。在早期术后并发症方面，UKA 组有 1 例下肢静脉血栓形成，TKA 组有 1 例因糖尿病导致伤口愈合延迟，1 例深部感染。
UKA 和 TKA 都是治疗 KOA 的非常成功的选择，但 UKA 的使用可以促进术后膝关节功能的恢复，减少术后并发症，并获得比预期更满意的效果。
