Tendoscopic debridement for stage I posterior tibial tendon dysfunction.

Our objective is to assess whether the tendoscopic synovectomy is effective to control the stage I posterior tibial tendon dysfunction. Our study is a retrospective one. The participants, six patients with stage I posterior tibial tendon dysfunction, were treated with tendoscopy with synovectomy for the past 3 years. The results show that this is a safe procedure and we could achieve similar effectiveness as the traditional open procedure. There was no complication found. None of our patients have progressed to stage II or above posterior tibial tendon dysfunction. In conclusion, tendoscopic debridement is a minimal invasive surgery. It is effective to control the stage I posterior tibial tendon dysfunction. In addition, it had the advantages of smaller scars, less wound pain and a short hospital stay.
