Abstract:
Objective To compare the efficacies of unicompartmental knee arthroplasty (UKA) and high tibial osteotomy (HTO) in the treatment of unicompartmental osteoarthritis of inner knee. Methods The data of UKA and HTO in the treatment of unicompartmental osteoarthritis of the inner knee were retrospectively analyzed. The patients were divided into UKA group (65 cases) and HTO group (45 cases), and the operation time, intraoperative blood loss, postoperative 3d hemoglobin decrease and hospitalization time were compared. The femoral tibial angle (FTA), tibial platform rear angle (PS), insall-salvati (IS) index, Blackbume peezh (BP) index, American knee society knee score (KSS) and visual analogue scale (VAS) of two groups were compared before surgery, 3 months after surgery and 1 year after surgery. Results All the 110 patients were followed up, and the UKA group was lower than the HTO group in terms of operation time, intraoperative blood loss, postoperative 3d hemoglobin decrease and hospitalization time (P<0.05); in 3 months after surgery and 1 year after surgery, FTA, PS, IS, BP, VAS and KSS scores of UKA group and HTO group had statistically significant difference compared with those before surgery (P<0.05). Conclusions In the case of UKA and HTO in the treatment of unicompartmental osteoarthritis of the inner knee, relatively speaking, the former is more advantageous and has high safety, which is worthy of clinical promotion.
