To the Editor: Dr Solomon and colleagues1 point out that the physical examination can aid the primary care clinician in assessing the likelihood of a torn meniscal or ligamentous structure and in deciding whether a referral would be beneficial. However, the authors fail to provide information about the setting from which patients were recruited in the studies. All of the included studies seem to have been carried out in orthopedic settings, and the patients were likely referred for diagnostic arthroscopy. It is likely that in the process of patient selection many potential false negative test results were excluded, possibly overestimating the accuracy of these tests when extrapolating to the population encountered in primary care.
