Surgical Achilles tendon tears using platelet-rich fibrin matrices and conventional methods: Kinetics and kinematics evaluation

Abstract

Background.- The relationship between surgical technique and ankle biomechanical properties following surgery for acute rupture of the Achilles tendon has not yet been fully investigated. Objective.- To evaluate the clinical outcomes in patients with platelet-rich matrices and conventional techniques during Achilles tendon surgery. Methods.- Twelve patients who underwent surgical repair of a complete Achilles tendon (AT) rupture were divided into two groups, conventional open repair of the Achilles tendon group (noPrP) and platelet-rich fibrin matrices group (PrP). VISA-A, questionnaire was used. Calf circumference was measured. Gait analysis (ELITE system BTS) and ultrasound evaluation (GE Medical Systems) were performed and AT diameter was measured (ATTD). The follow-up was at 6 months. Results.- Differences were found between ATTDprp and ATTDnoPrp (P = 0.029) and in the stiffness in the hopping trial (P = 0.001). Conclusion.- Based on this study, we suggest that PrP surgery represents potential for enhanced healing and functional recovery.
