Kinematics in the diagnosis of meniscal lesions

We have studied the findings at operation of 336 knees with a preoperative diagnosis of a meniscus lesion. In 146 knees operated on by three surgeons, after a detailed history and clinical assessment, the findings confirmed the preoperative diagnosis in 116 knees (79.5 per cent). In 47 knees operated on after double contrast arthrography, the diagnosis was confirmed in 43 knees (91.5 per cent). In 50 knees operated on after a study of the instant centre of pathway, the diagnosis was confirmed in 45 knees (90 per cent). We found an improvement of preoperative diagnosis of up to 95.5 per cent when the combination of instant centre of pathway and arthrography were positive in 89 out of 93 knees.
