BACKGROUND Peroneal tendon disorders are common causes of lateral hindfoot pain.However,total rupture of the peroneal longus tendon is rare.Surgical treatment for this condition is usually a side-to-side tenodesis of the peroneal longus tendon to the peroneal brevis tendon.While the traditional procedure involves a long lateral curved incision,this approach is associated with damage to the lateral soft tissues(up to 24%incidence).CASE SUMMARY A 50-year-old female had developed pain at the lateral aspect of the hindfoot 1 mo after an ankle sprain while walking in the street.Previous treatments were anti-inflammatory drugs,ice,rest and Cam-walker boot.At physical exam,there was pain and swelling over the course of the peroneal tendons.Ankle instability and cavovarus foot deformity were ruled out.Eversion strength was weak(4/5).Imaging showed complete rupture of the peroneal longus tendon associated with a sharp hypertrophic peroneal tubercle.Surgical repair was indicated after failure of conservative treatment(physiotherapy,rest,analgesics,and ankle stabilizer).A less invasive approach was performed for peroneal longus tendon debridement and side-to-side tenodesis to the adjacent peroneal brevis tendon,with successful clinical and functional outcomes.CONCLUSION Peroneus longus tendon tenodesis can be performed through a less invasive approach with preservation of the lateral soft tissue integrity.
