Post-operative Achilles Tendinopathy Following Surgical Repair of Achilles Tendon Rupture Treated With Platelet-Rich Plasma: A Report of Two Cases

Post-operative Achilles tendinopathy (AT) can cause persistent, debilitating posterior ankle pain. The optimal treatment for recalcitrant AT following surgical repair of Achilles tendon rupture has not been well-established. Conservative management includes early weight-bearing and mobilization with structured physical therapy (PT) and a progressive return to activity. Despite completion of conservative measures, symptoms may persist long after surgical repair. Platelet-rich plasma (PRP) has been shown to effectively treat painful MSK conditions, including AT. There have been no published studies assessing the efficacy or safety of PRP injections to treat post-operative AT after repair of tendon rupture. We present two cases of refractory AT after surgical repair of a ruptured Achilles tendon treated with ultrasound (US) guided PRP injections.
