Medial Meniskusun Posterior Lezyonlarının Teşhisi

Posterior third lesions of the medial meniscus are frequently overlooked or misdiagnosed due to their subtle clinical presentation. Unlike anterior or mid-meniscus tears, posterior injuries rarely provoke synovial reactions or medial collateral ligament damage, and patients often cannot recall any traumatic onset. The paper describes characteristic symptoms such as joint instability during stair use or squatting, and “giving way” sensations. Occupations involving frequent crouching (e.g., farming, carpentry, plumbing) predispose to these injuries. Five diagnostic tests are outlined, notably the “duck walk test,” which replicates the original injury mechanism and yields a 91.4% positivity rate. Three case studies illustrate typical presentations and complications including recurrent synovitis, quadriceps atrophy, traumatic arthritis, and popliteal cysts. Early recognition through thorough anamnesis and strategic clinical testing enables timely intervention, reducing long-term joint damage.
