Proximal Medial Gastrocnemius Recession and Stretching Versus Stretching as Treatment of Chronic Plantar Heel Pain.
Foot & Ankle International 2018 December
BACKGROUND:: Plantar heel pain is a common disorder that can lead to substantial pain and disability. Gastrocnemius recession has been described as an operative treatment option, but there is a lack of prospective clinical and biomechanical outcome data. The aim of this study was to evaluate the clinical and biomechanical outcomes of gastrocnemius recession and stretching compared with a stretching exercise protocol for patients with plantar heel pain lasting more than 12 months.
METHODS:: Forty patients with plantar heel pain lasting more than 1 year were randomized to a home stretching exercise program only or to surgery consisting of a proximal medial gastrocnemius recession in addition to stretching exercises. The main outcome was the American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score at 12 months. Secondary clinical outcomes were the Short Form-36 (SF-36) and visual analogue scale (VAS) pain scores. The biomechanical outcome parameters were ankle dorsiflexion, Achilles function evaluated by a test battery with 6 independent tests, and plantar pressure evaluated by pedobarography. All data were obtained at baseline and at 12-month follow-up.
RESULTS:: The AOFAS score increased from 59.5 (42-76) to 88.0 (50-100; P < .001) for the operative group and from 52.5 (37-73) to 65.5 (31-88; P = .138) for the nonoperative group. The AOFAS, VAS pain, and SF-36 scores were significantly better in the operative compared with the nonoperative group at 12-month follow-up ( P < .05). Ankle dorsiflexion increased from 6 degrees (-3 to 15) to 10.5 degrees (0 to 23; P < .001). No between-group difference was observed for Achilles function at follow-up. The average forefoot plantar pressure for the operative group increased from 536 KPa (306-708) to 642 KPa (384-885) at follow-up ( P < .001).
CONCLUSION:: Proximal medial gastrocnemius recession with a stretching program was a safe and efficient method of treating chronic plantar heel pain.
LEVEL OF EVIDENCE:: Level 1, randomized clinical trial.
