Overcorrection and generalized joint laxity in surgically treated congenital talipes equino-varus.
Fifty patients with 70 previously operated clubfeet were assessed for overcorrection (using Tachdjian's flat foot grade) and generalized joint laxity. Twenty-eight patients (40 feet) had signs of generalized joint laxity using the Biro score and of these 25 feet were overcorrected. Of the 22 patients (30 feet) who did not have signs of joint laxity, only three overcorrected. This difference was statistically significant (P<0.001). A significant correlation exists between flat foot grade and laxity score (P<0.01). Overcorrection is a complication largely ignored in the published literature but we believe it is a serious complication of open release often resulting in poor long-term function. For those patients requiring surgery, the authors urge caution and recommend a limited surgical release, particularly if joint laxity is suspected, or the Ponseti method of treatment, which will probably avoid this complication.
