Abstract:
OBJECTIVE:To evaluate short-term clinical results of fixed-bearing unicompartmental knee arthroplasty (UKA) for patients with medial compartmental knee osteoarthritis.
METHODS:From January 2015 to December 2017, 62 patients with medial compartmental knee osteoarthritis were treated by fixed-bearing UKA. Among them, including 19 males and 43 females, aged from 47 to 83 years old with an average of (65.3±8.2) years old. The courses of disease ranged from 5 to 72 months with an average of(19.4±14.3) months. Postoperative complications were observed, VAS score was used to observe degree of pain relief, Hospital for Special Surgery(HSS) score was used to evaluate clinical effects.
RESULTS:All patients were followed up from 4 to 40 months with an average of(19.9 ±10.2) months. The incision healed well without blood transfusion, hospital stays ranged from 2 to 10 days with an average of (3.5±1.6) days. No deep infection, dislocation, loosing or per prosthetic fracture occurred after operation, while 1 patient suffered from posterior tibial vein thrombosis. HSS score improved from 69.9±7.2 before operation to 90.1±7.4 at final following-up, and 51 patients obtained excellent results, 9 patients good and 2 moderate. VAS score decreased from 3.8±0.9 before operation to 1.1±0.9 at final following-up.
CONCLUSIONS:Fixed-bearing UKA for medial compartmental knee osteoarthritis could obtain short-term clinical results for shorter hospital stay, less complications. with fewer complication and fast recovery.
