Follow-up
Return to Play
Return to play after a meniscus injury is expected. The timing varies and depends on the injury, treatment, and rehabilitation protocol. In many cases, athletes can return to their sport as soon as 2-3 weeks status post arthroscopic partial meniscectomy or 6-8 weeks status post meniscal repair.
Complications
Complications are discussed under Recovery Phase, Medical Issues/Complications. In the long term, meniscal repairs fail to heal in 5-10% of patients. Failure rates are lower when the tears are repaired in patients with concomitant ACL reconstruction.
In patients with untreated tears, enlargement of the tear and arthrosis are common. In patients who are status post partial meniscectomy, arthrosis is also a concern. However, arthroscopists are hopeful that long-term outcome studies will demonstrate that a partial meniscectomy can delay or prevent the degenerative changes noted by Fairbanks in patients who had open total meniscectomy.2
Prevention
Prevention of recurrent problems is accomplished best by reestablishing and maintaining knee fitness with strength, flexibility, and proprioception.
Miscellaneous
Medicolegal Pitfalls
- Patient expectations: Patients must understand the pathology of their own knees so they have appropriate expectations regarding outcome. Outcomes of treatment and prognosis are individualized depending on the type of injury and the associated joint pathology, such as articular cartilage damage and instability. Appropriate expectations are key to achieving subjectively successful outcomes.
Special Concerns
- Discoid meniscus
- Approximately 5% of the white persons have a disc-shaped lateral meniscus.
- Discoid meniscus often manifests as snapping of the knee in a patient younger than 10 years.22
- Radiographic signs include a widened joint space, squaring of the lateral femoral condyle, cupping of the tibial plateau, and hypoplasia of the tibial spine. MRI is the imaging technique of choice.
- Three types of discoid meniscus have been described.
- Type I – Complete, covers the entire plateau
- Type II – Incomplete
- Type III (Wrisberg ligament type) – Deficiency of the posterior meniscotibial ligaments, resulting in instability of the posterior horn
- No treatment is required for the asymptomatic discoid meniscus.
- Symptomatic type I and II discoid menisci warrant arthroscopic partial meniscectomy with saucerization to a normal meniscus shape. Likewise, a torn discoid meniscus requires partial meniscectomy; saucerization, with removal of the tear, often allows preservation of a meniscus of normal morphology. A symptomatic type III discoid meniscus requires stabilization of the posterior horn.
