Meniscal Injuries

meniscal injury treatment

Meniscal injuries are very common with every age group. As individual ages, the meniscus gets weaker and is injured even with minor trauma.>knee_meniscus_intro01-300x243

Features and functions of the meniscus

  • There are two menisci inside the knee. Both are located between the tibia and the femur. The medial meniscus is C-shaped located inside and extremely close to the knee. The lateral meniscus is U-shaped and located on the outer side of the knee.

  • Functionally, the menisci act as shock absorbers – the forces are spread out across the joint.

  • Walking and running put two times and eight times of body weight on the knee respectively – the back of the menisci takes the greatest amount of pressure when the knee bends

  • The menisci also protect the articular cartilage from taking too much pressure

  • The surface of the shinbone is converted into a socket to stabilize the flat surface

Causes for meniscal injuries

Meniscal injuries are related to sports activity at younger ages and degeneration at ages older than 30.

Symptoms of meniscal tears and injuries

Signs of meniscal injury can be diagnosed only after a thorough evaluation of the patient’s history. The mechanism of the injury such as squatting or changes in position is addressed first. Other symptoms noticed will be:

  • Intermittent pain along the joint line

  • Complaints of catching, locking or a sensation of giving away are noticed

  • Delayed swelling – recurrent effusions are a characteristic typical to degenerative tears

  • Physical examination reveals tenderness to the joint line, effusion and a diminished range of motion

Tests

  • McMurray test – observing reproducible click

  • Steinmann test – observation of an asymmetric pain with internal or external rotation

  • Thessaly test – locking and catching sensation observed and the lateral and medial joint line

  • Apley test – medial and lateral joint pain

Imaging studies

  • MRI – examining and establishing intra-articular disorders and all meniscal pathology

  • Arthrography – along with magnetic resonance imaging

  • Plain radiography – observing posteroanterior 45 deg. flexed view, Merchant patellar view and anteroposterior weight-bearing view
