Patient reported outcomes and ankle plantarflexor muscle performance following gastrocnemius recession for Achilles tendinopathy: A prospective case-control study.

BACKGROUND

Prospective studies to guide the application of a gastrocnemius recession for Achilles tendinopathy are limited. Our aim was to prospectively evaluate patient reported outcomes and muscle performance.

METHODS

Patients with unilateral recalcitrant Achilles tendinopathy who received an isolated gastrocnemius recession (n=8) and a healthy control group (n=8) were included. Patient reported outcomes, ankle power during walking and stair ascent, and the heel rise limb symmetry index (total work) were collected.

RESULTS

Improvements in pain and self-reported function were observed (six months and two years). Sport participation scores reached 92% by two years. Patients demonstrated lower ankle power during stair ascent and decreased limb symmetry during heel rise six months following treatment (p≤.02).

CONCLUSIONS

Study findings regarding long-term improvements in patient pain, self-reported function and sport participation, and early preservation of ankle function during walking, can help refine patient selection, anticipated outcomes, and rehabilitation strategies.
