Abstract:
ObjectiveTo evaluate effect of periarticular osteotomy in the treatment of asymmetrical ankle arthritis.MethodsSixty-five patients with asymmetrical ankle arthritis were treated with periarticular osteotomy between February 2005 and May 2011,including 43 females and 22 males,aged from 35 to 74 years (mean,55.5 years).According to the Takakura classification of ankle arthritis,there were 29 patients in grade 2,32 in grade 3 and 4 in grade 4.Supramalleolar tibial osteotomy were performed in 20 patients,supramalleolar tibial and fibular osteotomy in 12,supramalleolar osteotomy combined with calcaneal osteotomy in 30 patients,and supramalleolar tibial and fibular osteotomy combined with calcaneal osteotomy in 3patients.Forty three patients underwent ligament reconstruction procedures.Based on radiographs,the tibial anterior surface angle (TAS) and tibial lateral surface angle (TLS) were compared before and after operation.AOFAS-AH score was used to evaluate the function of the ankle.ResultsFifty-nine patients were followed up for an average of 35.7 months (range,7 to 94 months).Bone healing was observed in all patients,and the average healing time was 7 to 8 weeks.The average AOFAS-AH score was improved from 49.7 points preoperatively to 78.6 points 12 months postoperatively.Tbe average TAS and TLS was improved from 86.1° and 70.0° preoperatively to 93.9° and 81.5° 6 months postoperatively,respectively.Delayed wound healing occurred in 5 patients,which was resovled after nursing care.Forty-two patients felt excellent about results,15 felt good and 2 fell fair.ConclusionPerarticular osteotomy is a sound method in the treatment of asymmetrical ankle arthritis,based on chosing proper patients.The procedure can decrease the contact pressures on the degenerated cartilage and prolong the life span of the ankle.
