Septic arthritis in association with primary lymphoedema.

The association between b-haemolytic streptococcal arthritis of the knee and primary lymphoedema is reported. This condition appears to resolve slowly using conventional methods of treatment, in the form of immobilisation and antibiotic therapy. However, the penetration of penicillin into the joint in these two patients was adequate, suggesting that there is no place for the intra-articular injection of antibiotic in the treatment of this condition.
