Massage therapy · Kitchener–WaterlooKnee Medial Collateral Ligament Rupture

This is a significant knee injury. However, the MCL is known to heal well on its own, and when the MCL is the only ligament torn, even a complete tear is usually treated without surgery at first (Svantesson et al., 2024). Grade III MCL injuries mostly heal (Sherwood Forest Hospitals NHS Foundation Trust, 2026). Often, though, it is not just the MCL that's torn: the most severe MCL tears usually happen at the same time as an anterior cruciate ligament (ACL) tear, and the medial meniscus can be torn too (American Academy of Orthopaedic Surgeons, n.d.). Rehabilitation can be long, and after a ligament rupture the normal stability of the knee can be affected.

The anterior cruciate ligament is the one that prevents the femur from sliding backward along the tibia. The medial and lateral collateral ligaments make sure the femur doesn't slide from one side to the other. It is the posterior cruciate ligament that prevents the femur from sliding forward along the tibia.

Collateral ligaments are found on either side of the knee. The medial ligament connects the tibia to the femur, while the lateral ligament connects the fibula to the femur. Collateral ligaments control movement of the knee sideways and brace it against any unusual movements (American Academy of Orthopaedic Surgeons, n.d.).

There are also two pads in the knee, like cushions, known as the menisci. Each meniscus acts like a shock absorber in the knee to dampen forces. Meniscus injuries can happen at the same time as MCL tears (American Academy of Orthopaedic Surgeons, n.d.).

1. Brace

Your doctor may fit a hinged knee brace, which lets the knee bend and straighten but limits side-to-side movement while the ligament heals (American Academy of Orthopaedic Surgeons, n.d.; Svantesson et al., 2024). How long it is worn varies, and your doctor will tell you how and when to stop using it (Sherwood Forest Hospitals NHS Foundation Trust, 2026).

2. Strengthening Exercises

Once the swelling and pain have settled enough, you can begin exercises that restore strength and normal movement in the knee. If you are sore while exercising, go more slowly to avoid further irritation. Normal healing of an MCL injury can take around 6 to 12 weeks, and it is normal to have some discomfort and swelling for longer than this (Sherwood Forest Hospitals NHS Foundation Trust, 2026). Recovery is likely to take longer if other parts of the knee are injured as well; I'll guide you on what to expect, alongside your medical team.

Options outside my scope

• Surgery: an operation to repair or reconstruct the MCL may be advised, mainly when other ligaments such as the ACL are also torn, for certain types of complete tear, or if the knee does not improve with non-surgical treatment (Svantesson et al., 2024; MedlinePlus, 2025).

How I can help (see the My Approach tab)

• Hands-on work for swelling, stiffness and the muscles around the knee
• Strength and balance exercises within your medical team's limits
• Scar work after surgery, once your surgeon clears you
• A gradual return to sport once your medical team agrees

If your foot loses feeling, feels cold or changes colour, call 911 (see When to get help).
