Unicompartmental knee arthroplasty (UKA) lends itself to the outpatient surgical setting. Prior literature has established a low rate of readmission and post-operative complications when performed in a hospital outpatient setting (HOP). To our knowledge, there have been no studies comparing complications of UKA performed at an ambulatory surgery center (ASC) and those in a HOP.
We retrospectively reviewed all patients who underwent outpatient UKA by a single surgeon from 2012 to 2016. In all 569 outpatient UKAs were performed: 288 in the ASC group and 281 in the HOP group. We compared the groups with regard to all complications within the first 90 days after surgery.
Thirty minor and major complications occurred within 90 days (5.3%). There was no difference in the overall complication rate between groups (ASC 12, 4.2%; HOP 18, 6.4%) (P = .26). Day of surgery admission occurred once in the HOP group (0.4%) and did not occur in the ASC group (P = .49). There was 1 visit to the emergency department (ED) <24 hours from surgery in each group (ASC 0.3%, HOP 0.4%) (P = 1.0). ED visits occurred within 7 days in 3 ASC cases (1.0%) and 4 HOP cases (1.4%) (P = .72). Re-admissions in the first 90 days occurred in 5 ASC cases (1.7%) and 8 HOP cases (2.8%) (P = .41).
UKA at an ASC has a low early postoperative complication rate without increased risk of re-admission or ED evaluation when compared to UKAs performed at a HOP.
单髁膝关节置换术（UKA）适合在门诊手术环境中进行。先前的文献已经确定，在医院门诊环境（HOP）中进行手术时，再入院率和术后并发症的发生率较低。据我们所知，尚无研究比较在门诊手术中心（ASC）进行的 UKA 和在 HOP 进行的 UKA 的并发症。
我们回顾性分析了 2012 年至 2016 年间由一位外科医生进行的所有门诊 UKA 患者。共有 569 例门诊 UKA 患者：288 例在 ASC 组，281 例在 HOP 组。我们比较了两组患者术后 90 天内的所有并发症。
90 天内发生了 30 例轻微和严重并发症（5.3％）。两组之间的总并发症发生率没有差异（ASC 12 例，4.2％；HOP 18 例，6.4％）（P=0.26）。HOP 组有 1 例（0.4％）手术当天入院，而 ASC 组无入院（P=0.49）。每组均有 1 例（0.3％，HOP 0.4％）在手术后 24 小时内到急诊部（ED）就诊（P=1.0）。ED 就诊发生在 ASC 组的 3 例（1.0％）和 HOP 组的 4 例（1.4％）（P=0.72）。在第一个 90 天内再入院的有 5 例（1.7％）在 ASC 组和 8 例（2.8％）在 HOP 组（P=0.41）。
与 HOP 相比，ASC 进行的 UKA 术后早期并发症发生率较低，且再入院或 ED 评估的风险并未增加。
