This prospective kohort study will follow 150 patients treated with proximal medial gastrocnemius recession for plantar fasciitts. Follow up time is two years and the main outcome is the Manchester Oxford Foot Questionnaire.
A regression analasys will be performed to identify possible patient baseline factors that may affect the effect of surgery,
Recent studies indicate that chronic plantar fasciitis can be treated effectively with Proximal Medial Gastrocnemius Recession (PMGR). In our hospital this treatment has been inocorporated into routine care. This prospective kohort study will follow 150 patients with chronic planatar fasciitis operated with PMGR study. The follow up time is 2 years and the study aims at documenting the effect of the surgery with PROMS (patient related outcome measures), MRI (magnetic resonnance imaging) and ankle movement measurements. 26 patient-related baseline factors will also be registered. A regression analysis will be performed to identify factors that may be predictive to the effect of PMGR surgery.

| Proximal Medial Gastrocnemius Recession | Procedure | Patients will be operated with PMGR as described by Barouk. No additional procedures will be performed. The surgery will be performed with the patients in a prone position under local anaesthetics. A 3-4 cm transverse skin incision is made in the popliteal fossa, the superficial fascia is opened, and the medial gastrocnemius with its tendon (aponeurosis) is located. The tendon is then cut while lifting it with clamps, and care is taken to cut only the white tendon while sparing the underlying muscle. While performing a dorsiflexion movement of the ankle, careful palpation of the muscle is done to ensure that all tendon strands are cut completely. The incision is closed in layers, and only soft dressings applied. Patients will be instructed to continue the stretching exercises and fully weight-bear from the first postoperative day. If needed, the patients will be allowed to use crutches during the first 2 weeks after surgery. Sutures are removed 2-3 weeks after surgery. |

Baseline data includes Age, sex, BMI, smoking, medication, diabetes, rheumatologic disease, employment, type of employment, education level, duration of symptoms, previous treatments, activity level, clinical varus/valgus deformity, use of insoles, previous surgeries in affected foot/ankle for other conditions, clinical hallux valgus deformity, symptomatic hallux valgus deformity, taylors bunion, stable/unstable ankle joint, dominant foot, MRI findings (2), X-ray finding (1): Heel spur. Total number of variables: 26 These data will later be used in regression analysis. |

EQ-5D is a validated generic health-related quality-of-life instrument. It consists of two parts: EQ-5D descriptive part and EQ-5D visual analogue scale. The descriptive part includes five dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression), each with three possible answers ("no problems", "some problems", and "major problems"). EQ5D VAS is a visual analogue scale of self-related overall health, ranging from 0 (worst imaginable health state) to 100 (best imaginable health state
