Tendoscopy in stage I posterior tibial tendon dysfunction

Stage I PTTD was defined by Johnson and Strom as tenosynovitis or tendinitis whereby tendon length remains normal, there is no hindfoot deformity, and diagnosis is basically clinical, characterized by swelling and tenderness posterior to the medial malleolus. The PTT has a hypovascular zone 40 mm pr...

Summary:Stage I PTTD was defined by Johnson and Strom as tenosynovitis or tendinitis whereby tendon length remains normal, there is no hindfoot deformity, and diagnosis is basically clinical, characterized by swelling and tenderness posterior to the medial malleolus. The PTT has a hypovascular zone 40 mm proximal to the insertion of the tendon and 14 mm in length. Pain often is localized to this portion of the tendon. Tendon power might be normal, and the patient can perform single heel rise, sometimes with slight discomfort. This condition is often misdiagnosed as ankle sprain, which delays correct diagnosis and early treatment that may improve symptoms, stop the disease process, and prevent the development of adult acquired flatfoot deformity. Ultrasonography is a valuable adjunctive diagnostic tool for stage I PTTD, but the authors always indicate MRI for accurate diagnosis in such patients. Patients with stage I PTTD are first treated nonoperatively with nonsteroidal anti-inflammatory drugs for 5 days, cryotherapy, local ultrasound, and a PTTD airlift brace (Aircast) for 3 to 6 months. If symptoms persist, surgical debridement and synovectomy has been suggested. PTT tendoscopic synovectomy is a minimally invasive and effective surgical procedure to treat patients with stage I PTTD. It has the advantages of less wound pain, and fewer scar and wound problems. If tendon tear is observed during tendoscopy, it must be repaired with nonabsorbable sutures using a 3- or 4-cm incision.
