Sinus tarsi syndrome is the clinical syndrome of lateral heel pain with local tenderness at the sinus tarsi and is frequently associated with a history of inversion sprain to the ankle. The lateral heel pain can be due to the capsuleligamentous structures lateral to the axis of the anterior and posterior subtalar joints. Anterior and posterior subtalar arthroscopies are needed to detect and treat the disorders of both joints. In this Technical Note, we describe the details of a 2-portal arthroscopic approach to both anterior and posterior subtalar joints. This allows complete examination of all the possible sources of lateral heel pain in sinus tarsi syndrome.

Prepatellar bursitis can be septic and aseptic. Treatment for prepatellar bursitis is determined primarily by the cause of bursitis and secondarily by the pathological change in the bursa. Nonoperative treatment is the mainstay of treatment, and bursectomy is indicated for intractable bursitis resistant to conservative treatment. Open bursectomy has significant risk of surgical site morbidity. In this Technical Note, the technical details of endoscopic resection of prepatellar bursa are presented. This minimally invasive technique has the advantage of better cosmetic results and fewer wound complications.
