JOINT EMPYEMA

Bacterial joint infection is rare but may have an unfavourable functio nal autcome. The different stages of purulent arthritis, depending on the pathophysiological developments, require different treatment measu res. Clinical examination, analysis of joint tap and arthroscopy are c rucial for diagnosis. Surgical management comprises: (1) open or arthr oscopic debridement with intensive flush lavage; (2) postoperative dra inage and flush lavage; (3) early and continuous active and passive mo tion. Recovery will be complete only if therapy is instituted as early as possible (within 3 days). Joint empyema must therefore be treated as a surgical emergency.
