Background Tibialis anterior (TA) tendinosis is rarely reported on in the literature. It is seen in patients older than 45 and causes weakness in dorsiflexion. This paper aims to describe surgical treatment and clinical outcomes. Methods Between 2015 and 2018, nine patients (six females, three males) with severe TA tendinosis with no tear (2), partial (1), or complete (6) underwent operative treatment. Patients underwent debridement and direct repair without augmentation, direct repair with fiber tape augmentation, tibialis posterior tendon (PTT) transfer, or tibialis anterior tendon (TAT) augmentation with a tendon autograft (n = 4). Autografts consisted of extensor digitalis longus (EDL) tendon, plantaris tendon, or both. Results Mean postoperative follow-up was 21.3 (range 8–31) months. All patients had a concomitant gastrocnemius recession, and three had hindfoot arthrodesis. Preoperative dorsiflexion strength was 0/5 for all and improved to 5/5 postoperatively in seven. The only current smoker developed wound dehiscence 2 weeks postoperatively and healed by 4. One developed marginal skin necrosis 3 weeks postoperatively and was treated successfully with casting. Conclusion Surgery reestablished function in individuals with TA tendinosis and allowed high level of satisfaction. Direct repair is possible. If the tendon gap is too large an autograft of EDL and plantaris tendon can be utilized. Level of evidence: Level III Retrospective Comparative Study
