Torn MCL and Meniscus: What to Know

The medial collateral ligament, or MCL, supports the inner side of the knee. The meniscus is a shock-absorbing cartilage structure between the thigh and shin bones. A twisting or side-impact injury can affect both. Inner-knee tenderness and swelling may occur with an MCL injury; catching, painful clicking or locking can point towards meniscal involvement, although symptoms overlap. Examination and sometimes imaging help define the injury.

Reduce twisting, pivoting, deep squats and impact while the knee is painful or unstable. A clinician may recommend Knee Bracing for protection during a phase of healing. Keep movement within a comfortable range and follow a graded strengthening plan. Physiotherapy can address swelling, knee motion, quadriceps control and balance. If sport is a goal, a Return-to-Sport Programme can test running, landing and change of direction progressively rather than relying on a calendar.

Seek prompt assessment if the knee locks, repeatedly gives way, becomes rapidly swollen or cannot bear weight. Emergency care is appropriate after major trauma with deformity, severe pain, numbness or a cold foot. Arrange review if pain, limited movement or instability continues despite reducing aggravating activity.

Ask whether the MCL is stable, whether the meniscus is displaced, what movements are restricted and whether a brace is needed. Ask how rehabilitation will protect the ligament while maintaining knee motion, and which tests mark readiness for work or sport.
