title: Retrograde synovial biopsy of the knee joint using a novel biopsy forceps.
abstract: Synovial biopsies of the knee joint are commonly performed arthroscopically with the patient under full or regional anesthesia. To overcome the effort, costs, and potential risks of surgery, we developed an office-based technique for retrograde synovial biopsy using a designated novel biopsy forceps. Using this technique, no arthroscopic or radiologic control is needed to perform rapid synovial biopsies of the knee joint. Concomitant aspiration of synovial fluid can be performed. A technical description of the procedure is given.
