Unicompartmental knee arthroplasty (UKA) has a faster short-term recovery than total knee arthroplasty (TKA). The purpose of this study was to determine the feasibility and safety of performing outpatient UKAs in a consecutive group of patients presenting with unicompartmental knee osteoarthritis.
A total of 105 consecutive patients underwent unicompartmental arthroplasty before noon with the intention of being discharged as an outpatient. All patients followed an established rapid recovery pathway to facilitate a same-day discharge. Post-operative complications and hospital readmissions were retrospectively recorded for all patients at one week and at three months after surgery.
All of the 105 patients (100 %) indicated for outpatient UKA could be discharged home on the same day of surgery. No patients required readmission within the first week post-operatively, while one patient required readmission between week one and week 12. The single patient who required readmission developed a post-operative infection requiring irrigation/debridement with polyethylene liner exchange and intravenous antibiotics.
Using an established, multidisciplinary, rapid recovery protocol, outpatient UKA is safe and feasible in the vast majority of patients.
单髁膝关节置换术（UKA）比全膝关节置换术（TKA）具有更快的短期恢复。本研究旨在确定在一组患有单侧膝关节骨关节炎的连续患者中进行门诊 UKA 的可行性和安全性。
共有 105 例连续患者在中午前接受单髁关节置换术，目的是作为门诊患者出院。所有患者均遵循既定的快速康复途径，以促进当天出院。所有患者在术后一周和三个月时均回顾性记录术后并发症和医院再入院情况。
所有符合门诊 UKA 条件的 105 例患者（100%）均可在手术当天出院回家。没有患者在术后第一周内需要再次入院，而有 1 例患者在第一周到第十二周之间需要再次入院。唯一需要再次入院的患者发生了术后感染，需要进行冲洗/清创术，并更换聚乙烯衬垫和静脉用抗生素。
使用既定的多学科快速康复方案，门诊 UKA 在绝大多数患者中是安全且可行的。
