Medial Gastrocnemius Myotendinous Junction Displacement and Plantar-Flexion Strength in Patients Treated With Immediate Rehabilitation After Achilles Tendon Repair

Context: Pathologic plantar flexion frequently occurs after operative repair of the Achilles tendon (AT) because of immobilization and non–weight bearing in the first weeks of traditional rehabilitation. Novel rehabilitation strategies that apply mobilization and weight bearing have been proposed, but their effects on medial gastrocnemius myotendinous junction displacement (MJD) and isometric plantar-flexion strength (PFS) are unknown. Objective: To compare the effects of 12 weeks of immediate versus traditional rehabilitation on MJD and PFS in patients with percutaneous AT repair and to compare AT rupture scores (ATRSs) during follow-up. Design: Controlled laboratory study. Setting: Human performance laboratory. Patients or Other Participants: A total of 26 amateur soccer players (age = 42.3 ± 9.7 years, body mass index = 29.5 ± 3.9 kg/m2) with percutaneous AT repair. Intervention(s): Athletes were randomly divided into 2 groups: an immediate group, given physical therapy from day 1 to day 84, and a trad...
