Abstrakt: The purpose of the study was to determine the histo-morphological effects on villous synovium after synovectomy using two different motorized synovial resectors and two different intensities ex-vivo. Thirty-three (n = 33) equine metacarpophalangeal/metatarsophalangeal joints were used. Synovectomy was performed along the dorsomedial/dorsolateral synovium (n = 66) using two motorized synovial resectors (aggressive full radius resector, AFRR, used at two intensities: single treatment, n = 24 vs. triple treatment, n = 21 vs. aggressive meniscus side cutter, AMSC, n = 21). Arthroscopic images were evaluated blindly for resector type and intensity. Histological images were evaluated descriptive for synovial morphology and the extent of tissue loss using a microscopic scale. Scanning electron microscopy described the synovial morphology. The synovectomized areas were specific for each resector used and distinguishable from arthroscopic images. The AFRR demonstrated a clear demarcation between treated and non-treated areas and removed the stratum synoviale completely including parts of the underlying stratum fibrosum. In contrast, the AMSC showed less clear demarcation, villous scaffolds and no involvement of the stratum fibrosum. Triple intense treated AFFR samples resulted in significantly deeper lesions compared to single treatments (p = 0.037) but could not be distinguished on arthroscopic images. The morphological effects on villous synovium differ according to the resector type used. The extent of synovial tissue loss cannot be estimated from arthroscopic images but histologically. The type and use of motorized synovial resector determines the morphological alterations of the treated synovium. Arthroscopic control is considered unsuitable to control synovectomy depth.
