Management of Posterior Root Medial Meniscus Tear with Avulsion Fracture

Understanding the Injury

• The MRI findings show a full-thickness posterior root detachment of the medial meniscus with a possible corticated avulsion fracture component, which can lead to medial meniscal extrusion and altered joint loading profiles in a patient with this type of injury 1
• Without proper treatment, this injury can accelerate the progression of knee osteoarthritis in patients with posterior root medial meniscus tears with avulsion fracture 2

Post-Surgical Rehabilitation

• Gradual return to activities with focus on quadriceps and hamstring strengthening to stabilize the knee is recommended for patients after surgical repair of posterior root medial meniscus tears with avulsion fracture 2

Alternative Management Options

• Conservative management is often recommended for degenerative meniscal tears, but it is not appropriate for acute traumatic posterior root avulsions with bony fragments, as stated by the BMJ 3

Common Pitfalls to Avoid

• Delayed treatment can lead to irreversible meniscal damage and accelerated joint degeneration in patients with posterior root medial meniscus tears with avulsion fracture 2

Follow-up Recommendations

• Long-term monitoring for development of osteoarthritic changes is necessary for patients with posterior root medial meniscus tears with avulsion fracture after surgical repair 2
