Arthroscopic hemitrapeziectomy with tendon interposition for arthritis at the first carpometacarpal joint

The first carpometacarpal (CMC) joint, also referred to as trapeziometacarpal joint, is the area of the hand most commonly symptomatic of osteoarthritis. Although there are a variety of surgical techniques that treat this condition, this article focuses on the technical aspects of arthroscopic hemitrapeziectomy with tendon interposition. Furthermore, this study evaluated the use of arthroscopy to treat CMC arthritis, with the expectation that an arthroscopic procedure would lead to low morbidity, quick recovery of function, rapid resolution of pain, and satisfactory results in patients' strength, range of motion, and pain relief. Early outcomes data indicate that all patients experienced statistically significant improvement in their pain scale rating at a mean of 11 months after the operation. All patients were satisfied with the outcome of their surgery. All patients would choose to have this surgery again. This study supports arthroscopic hemitrapeziectomy with tendon interposition as a safe and effective treatment for CMC arthritis.
