  • Effectiveness of double-plane high tibial osteotomy in treatment of medial compartment osteoarthritis

    Objective To investigate the effectiveness of double-plane high tibial osteotomy in treatment of medial compartment osteoarthritis. Methods The clinical data of 65 patients with medial compartment osteoarthritis who were treated with double-plane high tibial osteotomy between January 2014 and January 2017 was retrospectively analyzed. There were 28 males and 37 females. The age ranged from 46 to 75 years with an average of 53.2 years. There were 30 cases in the left knee and 35 cases in the right knee. The disease duration was 3-7 years (mean, 4.0 years). The patients had different degrees of pain in the knee joint and difficulty walking. The knee joint compression test was positive. The knee joint function was evaluated by Hospital for Special Surgery (HSS) score and knee society score (KSS) clinical and functional scores. The visual analogue scale (VAS) score was adopted to pain measurement. The healing of osteotomy was observed by X-ray films during follow-up; the femur tibia angle (FTA), posterior tibial slope (PTS), medial proximal tibial angle (MPTA), and knee varus angle (KVA) were also calculated. Results All the incisions healed by first intention after operation. Only 1 case had numbness of the toe, and the symptoms disappeared after symptomatic treatment. All patients were followed up 13-18 months with an average of 15.4 months. X-ray examination showed that all patients had bone healing at 12 weeks after operation. There were significant differences in MPTA, FTA, PTS, and KVA between pre- and post-operation (P<0.05). There was no significant difference in above parameters among 1 week, 6 months, and 12 months after operation (P>0.05). There was no loosening and rupture of the fixator during the follow-up. The HSS score and KSS clinical and functional scores at 12 months after operation were significantly higher than those before operation (P<0.05). The VAS scores at 1 week, 6 months, and 12 months after operation were significantly lower than that before operation (P<0.05). Conclusion Double-plane high tibial osteotomy for medial compartment osteoarthritis can effectively relieve pain symptoms and improve joint function.

  • Arthroscopy combined with high tibial osteotomy for the treatment of knee medial compartment osteoarthritis and its influence on cartilage injury

    ObjectiveTo investigate the effectiveness of arthroscopy combined with high tibial osteotomy (HTO) in the treatment of knee medial compartment osteoarthritis and its influence on cartilage injury.MethodsThe clinical data of 57 patients with knee medial compartment osteoarthritis treated with arthroscopy combined with HTO between March 2017 and March 2019 were retrospectively analyzed. There were 27 males and 30 females with an average age of 52.4 years (range, 44-57 years). The disease duration ranged from 3 to 6 years, with an average of 3.6 years. Twenty-one cases were grade Ⅰ and 36 cases were grade Ⅱ according to Kellgren-Lawrence classification. Flexion contracture of knee joint ranged from 0° to 8° with an average of 1.36° and varus deformity ranged from 5° to 10° with an average of 7.60°. Preoperative arthroscopic evaluation showed that there were 11 cases with grade Ⅰ, 42 cases with gradeⅡ, and 4 cases with grade Ⅲ according to the international cartilage repair classification system (ICRS). Lysholm score, American Hospital for Special Surgery (HSS) score, and International Knee Documentation Committee (IKDC) score were used to evaluate knee function before operation, at 3 months, at 1 year after operation, and at last follow-up. Visual analogue scale (VAS) score was used to evaluate pain. The mechanical medial proximal tibial angle (mMPTA) and femoral tibial angle (FTA) were measured before operation and at last follow-up. When the internal fixator was removed, the knee arthroscopy was performed again to explore the cartilage repair condition, and the regeneration level and maturity level were selected for cartilage grading evaluation.ResultsAll patients’ incisions healed by first intention after operation, and no incision infection or skin necrosis occurred. After operation, the knee joint function of the patients was significantly improved, the pain symptoms were relieved, and the force line measurement reached the target set before operation. The VAS score, Lysholm score, HSS score, and IKDC score were significantly improved at 3 months, 1 year after operation, and at last follow-up when compared with those before operation. They were gradually improved with the time and there were significant differences between time points (P<0.05). mMPTA and FTA were significantly improved at last follow-up when compared with those before operation (P<0.05). When the internal fixator was removed, the arthroscopic re-assessment found that the cartilage regeneration was classified into 10 cases of grade Ⅰ and 47 cases of grade Ⅱ; 18 cases of immature cartilage regeneration and 29 cases of mature cartilage regeneration were found in the knee joints of grade Ⅱ cartilage regeneration. There was no significant difference in the cartilage regeneration grade between different ICRS gradings (H=0.176, P=0.916), and the difference in maturity grading was significant (H=10.500, P=0.005).ConclusionArthroscopy combined with HTO for the treatment of knee medial compartment osteoarthritis can effectively improve the symptoms and function of the knee joint, and can promote the regeneration of articular cartilage.
