## Arthroscopy of the Basal Joint: Treatment of Arthritis with Soft-Tissue Interposition

Arthritis of the basal joint of the thumb is commonly

treated with open techniques involving total or subtotal

trapeziectomy and interposition arthroplasty. Multiple

procedures and variations have been described and good

data are available regarding the outcomes of these tech-

niques. Many are open procedures; however, an arthroscopic

technique is advantageous to minimize morbidity and has

been shown to have outcomes comparable to open

procedures (1-4).
