Surfers' Knot Causing Foot Pain in a Competitive Surfer.

Abstract

Abstract: A 49-year-old short-board goofy-stance competitive surfer presented with a 3-month history of bilateral, left foot pain associated with tender soft tissue plantar nodules. Magnetic resonance imaging of the left foot revealed foci of fibrotic tissue within the subcutaneous tissue adjacent to the first and fifth metatarsophalangeal joints compatible with surfers' knots. The patient underwent conservative treatment with oral ibuprofen as needed before competitions, topical diclofenac gel, wide toe box shoes, and use of a double-thick traction pad on his surfboard to alleviate the friction between the metatarsophalangeal joints of his left foot and the surfboard. He reported improvement of symptoms and full return to surfing at 8-month follow-up. We present a case of surfers' knots overlying the left first and fifth metatarsophalangeal joints of a male competitive surfer and highlight recommendations for successful conservative treatment options for symptomatic athletes.
