Arthroscopic Management of Elbow Osteoarthritis.

The incidence of osteoarthritis in the general population is low, but it can be seen in manual laborers, throwing athletes, and people dependent on crutches and wheelchairs. Patients often complain of pain at the terminal extents of motion, and imaging shows osteophyte formation at the tips of the coronoid and olecranon processes as well as thickening of the bone between the coronoid and the olecranon fossae. Recent advances in arthroscopic instrumentation and techniques have led to a growing interest in the arthroscopic treatment of elbow osteoarthritis. This article provides a review of basic arthroscopic elbow anatomy and the most common procedures, including diagnostic arthroscopy, loose body removal, and arthroscopic osteocapsular and ulnohumeral arthroplasty. As techniques advance, there might be interest in further procedures including arthroscopic-assisted interpositional arthroplasty. Although complications such as persistent drainage and nerve injury are frequently mentioned with elbow arthroscopy, the actual incidence of such complications remains low.
