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

## TL;DR

This paper reports two cases where platelet-rich plasma injections helped treat persistent Achilles tendinopathy after surgery.

## Contribution

The study is the first to report on the use of PRP for post-operative Achilles tendinopathy following tendon rupture repair.

## Key findings

- PRP injections were used to treat two patients with persistent Achilles tendinopathy after surgery.
- Ultrasound-guided PRP injections were found to be a potential treatment option for refractory cases.
- No prior studies had assessed PRP for this specific post-operative condition.

## Abstract

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.
