During a 20-month period, 382 arthroscopies were performed and the type of washout fluid obtained was noted. When a torn meniscus was found, the fluid was macroscopically abnormal in 97.4% of cases. A crystal clear washout was associated with no demonstrable pathology in over half the cases, the remainder having mainly patellofemoral joint pathology and other articular lesions. Only 6.3% of those with a clear fluid washout had meniscal pathology. Of those with abnormal fluid, 68% had meniscal pathology, with a normal arthroscopic examination being found in only 8.5%. In addition, when the fluid from traumatic effusions was examined microscopically, a typical droplet containing lipid crystals was found to be present and to account for an oily macroscopic appearance. These data support the use of fluid irrigation of the knee as a screening test for intraarticular pathology, especially of the menisci, that may allow a reduction in the number of negative arthroscopies.
在20个月的时间里，共进行了382例关节镜检查，并记录了所获得的冲洗液类型。当发现半月板撕裂时，97.4%的病例冲洗液在宏观上异常。超过半数的病例中，清澈的冲洗液与未发现明显病变相关，其余病例主要存在髌股关节病变和其他关节损伤。冲洗液清澈的患者中只有6.3%存在半月板病变。在冲洗液异常的患者中，68%存在半月板病变，只有8.5%的关节镜检查结果正常。此外，对创伤性积液的液体进行显微镜检查时，发现存在典型的含脂质晶体的液滴，这解释了其宏观上的油性外观。这些数据支持将膝关节液体冲洗用作关节内病变（尤其是半月板病变）的筛查试验，这可能会减少阴性关节镜检查的数量。
