A Combined Revision Surgical Technique for Failed Operative Lateral Epicondylitis With Concomitant Radial Tunnel Syndrome.

Lateral epicondylitis afflicts a large percentage of the population with most recovering through conservative treatment. The 5% to 10% of patients who undergo operative intervention are met with mixed results. Those that fail to improve often demonstrate a complex presentation of inadequate debridement of the "angiofibroblastic tissue," missed concomitant radial tunnel syndrome, and iatrogenic residual devascularized tissue resulting from the index procedure. To address all 3 of these causes of failure, the authors have developed a revision procedure that includes repeat debridement of residual tendinosis, decompression of the posterior interosseous nerve, and a vascularized anconeus muscle flap to help cushion soft tissue defects and promote a healthier environment for healing. Performed initially in part in 20 patients, this combined procedure has developed into our recommended treatment for these challenging patients.
