Seventy-six patients (83 ankles) with chronic lateral instability of the ankle were treated by a simple reconstructive operation, namely, a subperiosteal release on the distal part of the lateral malleolus. The released flap, including the insertion of both the anterior talofibular and the calcaneofibular ligaments, was reattached to the malleolus more proximally. Seventy-five patients (82 ankles) were examined at a mean of 24 months (range 12 to 70) after operation. In 78 ankles (95%) the result was excellent or good. Forty-four of the 51 patients (86%) whose sporting activities were restricted before operation had no restriction at follow-up. Recurrence of instability occurred in one ankle, following a further injury two years after operation.
76例（83个踝关节）慢性踝关节外侧不稳定患者接受了一项简单的重建手术，即在外踝远端进行骨膜下松解。松解的皮瓣，包括距腓前韧带和跟腓韧带的附着点，在更靠近近端处重新附着于外踝。75例（82个踝关节）患者在术后平均24个月（范围12至70个月）接受了检查。78个踝关节（95%）的结果为优或良。51例术前体育活动受限的患者中，44例（86%）在随访时不受限。1例踝关节在术后两年再次受伤后出现不稳定复发。
