Meniscus Tear — Causes, Diagnosis & Treatment
A meniscus tear is a common knee injury involving damage to the C-shaped cartilage that cushions the knee joint. Treatment options range from conservative management to arthroscopic surgery.
The menisci are two C-shaped pieces of cartilage in each knee that act as shock absorbers, distributing weight and providing stability during movement.
Meniscus tears can occur from acute trauma, especially during twisting movements, or from degenerative changes in older adults where the cartilage has become brittle with age.
Treatment depends on the type, location, and size of the tear, as well as the patient's age and activity level.
Types of Meniscus Tears
Bucket-handle tears: Large, displaced tears that can cause the knee to lock, preventing full extension. These often require urgent surgical treatment.
Horizontal cleavage tears: Tears that run parallel to the tibial plateau, more common in older patients with degenerative changes.
Radial tears: Tears that extend from the inner edge outward, disrupting the meniscus's ability to distribute load.
Complex tears: A combination of tear patterns, typically seen in degenerative menisci.

Frequently Asked Questions
Do all meniscus tears require surgery?
No. Small, stable tears in the vascular zone may heal with conservative management. Tears in older patients with degenerative changes may also be managed non-operatively.
What is the recovery time after meniscus surgery?
Recovery depends on the procedure. Partial meniscectomy: 4-6 weeks. Meniscus repair: 3-6 months with protected weight-bearing.
Can I walk after meniscus surgery?
Yes, but crutches may be needed for 1-2 weeks after partial meniscectomy and longer after meniscus repair to protect the healing tissue.
