Investigation on the long-term effect of high tibial osteotomy in the treatment of varus osteoarthritis of the knee
Objective To study the long-term effect of high tibial osteotomy in the treatment of varus osteoarthritis of the knee.Methods 49 patients with varus osteoarthritis of the knee were studied and divided into a study group and a control group according to different treatment methods,each consisting of 49 patients.The study group was treated with high tibial osteotomy,and the control group was treated with proximal fibular osteotomy.Comparison was made on surgical time,postoperative bed time,postoperative hospitalization time,intraoperative blood loss,postoperative pain score,knee function score,femoral-tibial angle,sleep index and quality of life score before and after surgery between the two groups.Results The surgical time of the study group was(142.75±25.34)min,the postoperative bed time was(7.69±1.34)d and the postoperative hospitalization time was(9.31±1.89)d,which were longer than(106.13±18.57)min,(6.15±1.08)d and(7.09±1.23)d of the control group;the intraoperative blood loss of(158.03±31.82)ml of the study group was higher than(90.74±22.31)ml of the control group(P<0.05).The pain scores of the study group were(5.16±0.70),(4.35±0.54)and(3.72±0.5)points on the 1st,2nd,and 3rd postoperative days,which were higher than(4.32±0.67),(3.71±0.50)and(3.18±0.49)points of the control group(P<0.05).1 year postoperatively,the Lysholm knee function score and femoral-tibial angle in both groups were better than those preoperatively;the study group had higher Lysholm knee function score of(87.75±8.14)points than(78.62±8.29)points in the control group,and greater femoral-tibial angle of(173.64±1.23)° than(172.09±1.15)° in the control group(P<0.05).1 year postoperatively,the sleep latency,actual sleep duration,and sleep quality score improved in both groups compared with those preoperatively;the study group had a shorter sleep latency of(33.79±7.94)min than(42.63±8.75)min in the control group,a longer actual sleep duration of(7.84±0.93)h than(6.79±1.02)h in the control group,and a lower quality of sleep score of(10.49±1.31)points than(12.36±1.58)points in the control group(P<0.05).1 year postoperatively,the quality of life score in both groups was higher than that preoperatively;the physical,psychological,environmental,and social scores were(89.75±6.48),(89.07±6.02),(90.14±6.15),and(89.96±6.27)points in the study group,which were higher than(82.93±6.85),(82.40±6.13),(83.27±6.30),and(83.14±6.54)points in the control group(P<0.05).Conclusion Although the short-term efficacy of high tibial osteotomy applied to varus osteoarthritis of the knee is not as good as proximal fibular osteotomy,the long-term efficacy of high tibial osteotomy is better than proximal fibular osteotomy,and it has better advantages in improving patients'knee function,knee varus,sleep quality and quality of life.
