Short-term Efficacy Of Open High Tibial Osteotomy Combined With Arthroscopy In The Treatment Of Knee Osteoarthritis

Objective: To study the short-term efficacy of open high tibial osteotomy combined with arthroscopy in the treatment of knee osteoarthritis.Methods: A retrospective analysis was made on the follow-up data of20 patients(21 knees)with medialcompartment osteoarthritis of the knee treated by open high tibial osteotomy combined with arthroscopy from November2017 to January2019.The American Knee Society Score(AKS),Lysholm score and pain were measured before and after the last followup.Visual analogue scale(VAS),femoral tibial angle(FTA),proximal tibial angle(MPTA)and other indicators were used to analyze the changes of AKS score,Lysholm score,VAS score,femoral tibial angle and proximal tibial medial angle before and after operation.Statistical analysis was used to evaluate the outcome of all the indicators.Results: Twenty patients(21 knees),6 males and14 females,with an average age of50.5(+5.9)years,were followed up for an average of7.4(+2.94)months(1-12 months).The AKS clinical score of patients increased from(54.25+6.62)preoperatively to(74.1+4.41)postoperatively.The Lysholm score of patients increased from(52.4+1.3)preoperatively to(67.4+8.8)postoperatively.The VAS score of patients decreased from(6.85+0.68)preoperatively to(2.6+0.66).The femoral tibial angle of patients was(188.8+3.18)° preoperatively and(171.45+2.9)° postoperatively,with a satisfactory correction rate of89.47%.The proximal medial angle of tibia was(81.34 +4.17)° before operation and(89.5 +1.05)° after operation.There were significant differences in AKS score,Lysholm score,VAS score,MPTA and FTA before and after operation(P < 0.05).Conclusion: Open high tibial osteotomy combined with arthroscopy in the treatment of knee osteoarthritis has satisfactory short-term clinical results,and can obtain good short-term results.HTO can change the distribution of abnormal force lines of lower limbs by operation,correct the progress of knee degeneration,restore normal knee motion and improve the quality of life of patients.It can delay or dispense with artificial joint replacement,and obtain better clinical results in the short term.The long-term and medium-term effects need further follow-up and research.
