[Posterior tibial tenoscopy. Case report]

Posterior tibial tendinitis occurs commonly in patients involved in sports activities. It may result from either excessive use or sudden overload of the tendon. This tendinitis may also occur in patients with systemic inflammatory conditions and is classified as posterior tibial tendon dysfunction stage I. Initial treatment, which has produced good results, is based on immobilization and rehabilitation. In cases without clinical improvement or in which tendinitis is associated with partial tendon rupture, open techniques may be used to perform tenosynovectomy and tendon revisions to improve painful symptoms. With the advent of minimally invasive techniques broad tendon revisions may be done that cause minimal damage or they may be combined with traditional techniques in cases of partial rupture. This paper describes the clinical case of a 35 year-old female patient with posterior tibial pathology and chronic pain. She underwent posterior tibial tenoscopy and was followed-up postoperatively for 24 months. Endoscopic and/or tenoscopic treatment is a simple and reproducible technique. We obtained excellent functional and cosmetic results in this patient. We need larger case series of patients subjected to this treatment.
