Range-of-motion improvement and complication rate in open and arthroscopic osteocapsular arthroplasty for primary osteoarthritis of the elbow: a systematic review.

Both OPEN and ARTHRO improved ROM and clinical scores. The Bayesian method indicated that although OPEN increased the flexion and flexion-extension arc more than ARTHRO, ARTHRO resulted in a relatively consistent surgical outcome. Additionally, OPEN caused relatively higher complication and re-operation rates than ARTHRO.
