The development of good quality small-diametered arthroscopes and refined arthroscopic techniques has contributed to the improvement of the subtalar arthroscopy. The therapeutic indications are synovectomy, removal of loose bodies, debridement and drilling of osteochondritis dissecans, excision of subtalar impingement lesions and osteophytes, lysis of adhesions for post-traumatic arthrofibrosis, removal of a symptomatic os trigonum, calcaneal fracture assessment and reduction, and arthroscopic arthrodesis of the subtalar joint. The subtalar arthroscopy can be done in supine position using thigh holder or in lateral decubitus position. The arthroscope generally used is a 2.7-mm 30 degrees short arthroscope. Noninvasive distraction with a strap around the hindfoot can be helpful. Usually anterolateral, middle and posterolateral portals are utilized for inspection and instrumentation within the joint. Twoportal posterior subtalar arthroscopy in prone position can be performed as well with 4.0-mm 30 degrees arthroscope, depending on the type and location of the subtalar pathology. The subtalar arthroscopy is a technically demanding procedure, which requires proper instrumentation and careful operative technique. Possible complications are nerve damage and persistent wound drainage.

Os trigonum syndrome is a clinical disorder characterized by posterior ankle pain which occurs in excessive plantar flexion. The pain is elicited by the impingement of os trigonum between the calcaneus and the posterior edge of tibial plafond. Mostly, symptoms can be improved with nonsurgical management, however surgery is required for refractory cases. We report of a case of os trigonum syndrome in a female ballet dancer, which was successfully treated with subtalar arthroscopic excision of os trigonum.

The subtalar joint is a complex joint that is functionally responsible for inversion and eversion of the hindfoot. Advances in optical technology and surgical instrumentation have allowed the arthorscocpic surgeon to investiagate the small joints including the subtalar joint. Indications for subtalar arthroscopy include pain, swelling, stiffness and locking. Therapeutic indications include treatment of chondromalacia, osteophytes, arthrofibrosis, synovitis, loose bodies, osteochondral lesions, excision of a painful os trigonum, arthrodesis, and FHL tendinopathy. Contraindications to subtalar arthroscopy include infection, advanced osteoarthritis with deformity, severe edema, poor vascularity and poor skin quality. Subtalar arthroscopy is a technically demanding and difficult procedure that should only be performed by experienced surgeons. With proper instrumentation and careful operative techniques, satisfactory results may be obtained with minimal morbidity.

Synovial chondromatosis is an uncommon disorder characterized by cartilaginous proliferation within the synovial membrane of the articular joint. Smaller joints are rarely affected and it may be progressed to osteochondromatosis after ossification or calcification of metaplastic cartilage. It is commonly presented in the third to fourth decade of life, but rarely presented in adolescence. We report a unique case of synovial osteochondromatosis of the subtalar joint in 14-year-old baseball player. Arthroscopic removal of loose body and complete excision of the osteochondral mass with concomitant synovectomy resulted in satisfactory outcome without recurrence at final follow-up.
