title: [Differential diagnosis of synovitis. Correlation of arthroscopic-biopsy to clinical findings].
abstract: Histological examination of 1660 biopsies (2-5 mm) of the synovial membrane of 317 patients were obtained by arthroscopic dissection; in 70% of all cases non-specific changes were revealed and in 30% specific changes. The findings included different stages of proliferation of the superficial layer, uncharacteristic inflammatory reactions of the stratum synoviale and fibrosis of the stroma, vascular proliferation and pseudopolypoid thickening of the synovial membrane. The histomorphological findings can only be interpreted reliably and a pathogenetic classification obtained, e.g., detritus synovialitis, rheumatoid arthritis or post-traumatic changes, if the arthroscopic findings conclude an exact documentation of the biopsy site and the clinical findings.
