To Compare The Short-Term Efficacy Of Unico-Mpartmental Knee Arthroplasty(UKA) And High Tibial Osteotomy(HTO) In The Treatment Of Medial Compartment Osteoarthritis Of The Knee

Objetive:To compare the early effects of UKA and HTO in the treatment of medial ventricular osteoarthritis of the knee,and to evaluate the difference in the efficacy of the two kinds of surgery,so as to provide reference for the surgical treatment of medial ventricular osteoarthritis.Method:A retrospective analysis was performed on 30 patients with medial compartment osteoarthritis of the knee who received UKA or HTO surgery from June 2020 to June 2022 and met the inclusion criteria.They were divided into two groups according to the surgical method,namely UKA group and HTO group,with16 patients included in UKA group.Fourteen patients were included in the HTO group.Perioperative observation indexes such as K-L grading,operation duration,intraoperative bleeding and laboratory test indexes were observed and recorded in the two groups.Clinical effects were recorded for Range of motion(ROM)(Figure3),Oxford Knee Score(OKS),Femorotibial angle,(FTA)(Figure 3),SF-12 health questionnaire(Short form 12),Numerical Pain Rating Scale(NPRS).Result:UKA or HTO can be used in the treatment of 55-65 year old patients with medial ventricular osteoarthritis.Postoperative pain relief and functional recovery of patients have definite curative effect in the early stage.1.Perioperative data:Operation duration:(81.17±7.32)min in UKA group;HTO group was(83.21±8.12)min;Tourniquet duration was(60.01±4.23)min in UKA group and(62.11±4.12)min in HTO group.Intraoperative bleeding was(150.12±1.21)ml in UKA group and(170.34±2.31)ml in HTO group.Incision length was(8.09±0.12)cm in UKA group and(8.12±0.31)cm in HTO group.Compared with the above data,P > 0.05 was not statistically significant(see Table 1).All the incisions in the two groups healed well in the first stage,and no complications such as postoperative infection occurred.2.Evaluation of clinical efficacy: Before and after surgery,knee ROM,Oxford Knee Scale(OKS),tibiofemoral Angle(FTA),SF-12 health questionnaire score,and Numerical Pain Rating Scale score(NPRS)were compared between the two groups,and the differences were statistically significant(P < 0.05).At the second year of follow-up,the above indexes were compared between the two groups,and there was no statistical significance(P > 0.05).Regular postoperative review X-ray indicated that the UKA and HTO tibial plates were in good position without loosening of the implants and implants.Conclusion:Intragroup and intergroup comparisons of the Oxford Knee Joint Rating Scale(OKS),tibiofemoral Angle(FTA),SF-12 Health Questionnaire,and Numerical Pain Rating Scale(NPRS)showed that :1.For 55-65 year old patients with medial compartment osteoarthritis of the knee,both UKA and HTO can achieve satisfactory early efficacy in relieving knee pain and improving knee function.2.Middle-aged patients with medial ventricular osteoarthritis aged 55-60 years are more likely to choose HTO.3.For elderly patients aged 60-65 years old,UKA is recommended,and the hospital stay of HTO is longer than that of UKA,and the tibial implant needs to be removed through a second operation,and the implementation of the second operation is bound to be accompanied by related risks.If the patient has related underlying diseases or insufficient cardiopulmonary function,the risk degree will be greatly increased.Many patients prefer to choose UKA based on such factors as short recovery period,less trauma,good proprioception,and no need to remove the implant or undergo a second operation at a later stage.
