Outpatient knee arthroscopy under local analgesia can be performed solely as a diagnostic procedure. The aim was to estimate the diagnostic precision of such arthroscopy as compared to the diagnosis made during a secondary therapeutic operation, and to describe the flow of patients and the costs of this treatment strategy.The records of 371 consecutive patients, who had a diagnostic knee arthroscopy performed under local analgesia, were reviewed retrospectively. The diagnosis made during the diagnostic arthroscopy (371 patients) and a later therapeutic operation (135 patients) were extracted and the patients were asked to fill in a questionnaire.The diagnostic arthroscopy could not be completed in 11 cases. No further operation was necessary in 188 patients. A secondary therapeutic operation was performed in 135 patients. In only 54% of these was the same diagnosis made during the diagnostic and the therapeutic operations. Only half of the 278 patients (75%) who returned the questionnaire, found that the diagnostic procedure had been pain free.With respect to the costs, the diagnostic arthroscopy cannot be recommended. Most economic was the strategy in which the diagnostic and therapeutic operations were performed together as an outpatient procedure. The relatively poor diagnostic precision of arthroscopy is surprising and should be kept in mind when patients continue to have unexplained complaints in the knee, despite a normal arthroscopy. |
