Abstract:Objective To investigate the efficacy of different osteotomy methods combined with arthroscopy in the treatment of medial knee osteoarthritis.Methods A total of 124 patients with medial knee osteoarthritis in the Eighth People's Hospital of Hebei Province from January 2019 to January 2021 were selected and randomly divided into a double plane group (n=62) and a single plane group (n=62).Both groups underwent arthroscopy and high tibial osteotomy (HTO).The biplane group underwent biplane osteotomy,and the single plane group underwent single plane osteotomy.All patients were followed up for 6 months.The perioperative indicators,complications and the excellent and good rate of knee joint function recovery of the two groups were counted and compared the relevant indexes of lower limb force line,including knee varus angle (KVA),femoral tibia angle (FTA),medial proximal tibial angle (MPTA),American hospital for special surgery knee score (HSS),and visual analogue scale (VAS) before and 6 months after surgery.Results (1)Follow-up of 6 months showed that the bone healing time of the biplane group was shorter than that of the single plane group (P<0.05).(2)The MPTA of the biplane group was higher than that of the single plane group,and the FTA and KVA of the biplane group were lower than those of the single plane group at 6 months after operation (P<0.05).(3)The HSS score of the biplane group was higher than that of the single plane group at 6 months after operation,and the VAS score was lower than that of the single plane group (P<0.05).(4)The complication rate of the biplane group was 1.61%,and the single plane group’s complication rate was 8.06%.The difference was not statistically significant (P>0.05).(5)The excellent and good rate of knee function recovery in the biplane group(88.71%) was higher than that in the single plane group (74.20%) at 6 months after operation (P<0.05).Conclusion Arthroscopic combined with biplane osteotomy is superior to arthroscopy combined with single plane osteotomy in improving knee joint function,pain score,lower limb force line and fracture healing.It can be used as one of the effective method to treat medial knee osteoarthritis.
