Uncemented endoprosthesis in a female patient with chronic juvenile monoarthritis of the knee (case report)]

A case report of an 18 year-old female patient with juvenile rheumatoid monoarthritis (JRA) of the knee joint, whose treatment the authors have been following up during the last 14 years is presented. Previously known and reported difficulties and complications in the diagnosis of chronic juvenile rheumatoid monoarthritis are related with special reference to a specific case, a female patient in whose case the correct diagnosis and adequate treatment was begun three years after the first onset of symptoms. At the age of 15, the patient developed knee ankylosis of 20 degrees in flexion. Following this dezarthrodesis of the knee joint, cementless total knee arthroplasty was performed. The postoperative results are very encouraging, the knee joint is stable, the passive range of movement is 5/90 degrees, while the active range of motion is 10/80 degrees. Total knee arthroplasty helped to correct the previously present inegality of the lower extremities, while the problem of an exceptionally thick patella was resolved by coronary (frontal) osteotomy of the patella. The presented case once again confirms that in selected JRA patients cementless knee arthroplasty can achieve excellent results.
