Abstract
Background. Ankle tendon augmentation with biological matrixes has been shown to be beneficial, especially for Achilles tendon rupture as it adds to the integrity of the repair. Biologic matrix augmentation has been used increasingly in chronic and complex injuries where reinforcement is required. The objective of this study was to present outcomes of a series of patients who underwent tendon repair augmented with a new biologic matrix. Methods: Sixteen patients underwent ankle tendon repair, augmented with Proformix biologic tissue matrix. Patients were evaluated pre- and postoperatively for function and pain, and were followed for up to 3 years for complications. Results: This study included 10 females and 6 males, with a mean age of 44.6 years (range, 23-71 years). Patients were evaluated at 2 months postoperatively, and then further followed for a mean 19.0 months (range 7-38 months) to assess complications and reinjuries. Foot and Ankle Disability Index scores significantly increased from preoperatively (38.3) to 2 months postoperatively (85.2) (P < .001). Furthermore, there were no reports of reruptures or significant complications. Conclusions: Weakness or rupture in tendons of the foot, especially the Achilles tendon, can be treated surgically and the repair augmented with Proformix, a new, biological matrix. Our study presented a series of 16 patients whose surgical repairs had been augmented with the new biological matrix, all of whom have achieved excellent results.
