Intracapsular pressure monitoring during arthrographic evaluation of painful hip prostheses

Aspiration-arthrography with continuous monitoring of intraarticular pressure and volume was performed on 10 consecutive patients with painful total hip arthroplasties. Five of these patients demonstrated clinical and arthrographic evidence of adhesive capsulitis, a condition that was associated with a dramatic rise of intraarticular pressure as increasing amounts of contrast material were introduced. The precise etiology of adhesive capsulitis is not clear.
