OBJECTIVE: To describe the chiropractic management of a patient suffering from a right lateral meniscus tear concurrent with calcium pyrophosphate dihydrate (CPPD) deposition disease. CLINICAL FEATURES: A 51-yr-old bus driver suffered from right knee pain (7 on a 1-10 pain scale). The onset of the pain was gradual and increased during braking and accelerating. Palpatory tenderness was noted at the right lateral knee joint line and the inferior lateral margin of the patella. Active resistive range of motion (ROM) in the knee during extension was painful throughout the full ROM, whereas passive ROM was restricted in flexion at 110 degrees. A positive McMurray's test reproduced pain at the knee. Radiographic analysis revealed CPPD deposition disease, and magnetic resonance imaging revealed a probable "parrot's beak" tear in the posterior horn of the right lateral meniscus. INTERVENTION AND OUTCOME: The patient was treated conservatively. He was instructed not to put weight on the knee and not to return to work for 5 days. Initial treatments involved the use of ice and interferential electrical stimulation along with glucosamine sulfate supplements. Bicycling, weight lifting for general fitness and general knee strengthening exercises were prescribed. Approximately 5 months after initial treatment, the patient was lost to follow-up; 12 months later, he returned for treatment because of a recurrence. Physical examination at that time revealed knee pain rated at 3/10 but there was no pain upon palpation, McMurray's test was negative and right knee ROM was full without pain. CONCLUSION: A patient suffering from CPPD can be managed by conservative means. The pathophysiology, clinical features and management considerations in the treatment of the patient's condition(s) are also discussed.
