High tibial osteotomy combined with lateral retinacular release for the treatment of knee varus osteoarthritis with lateral patellar compression syndrome / 中国骨伤

ABSTRACT

OBJECTIVE@#To investigate the clinical effect of high tibial osteotomy combined with arthroscopic lateral retinacular release in the treatment of knee varus osteoarthritis.@*METHODS@#From October 2017 to April 2019, a retrospective analysis was performed on 43 patients with knee varus osteoarthritis and lateral patellar compression syndrome treated by high tibial osteotomy combined with arthroscopic lateral retinacular release. There were 15 males and 28 females, aged 53 to 72(62.05±5.17) years. The visual analogue scale(VAS), Lysholm, and the knee range of motion were used to evaluate knee pain and functional recovery before operation, 2 weeks, 3 months and 12 months after operation. And the congruence angle (CA), patellar tilt angle (PTA), and femala-tibial angle (FTA) were measured respectively before and 12 months after operation to evaluate the congruence of patellar joint, and the improvement of line of gravity of lower limb.@*RESULTS@#All 43 patients were followed up for more than 12 months, with a follow-up time of 14 to 28 (19.60±4.50) months. The VAS scores decreased from 6.65±0.65 before operation to 2.16±0.95, 0.51±0.77 and 0.33±0.64 at 2 weeks, 3 months and 12 months after operation, and the difference was statistically significant (@*CONCLUSION@#High tibial osteotomy combined with arthroscopic lateral retinacular release can relieve weight-bearing pain in frontal axis and improve the function of knee in sagittal axis.
