What can go wrong after an MCL tear?

Stiffness

The MCL heals most reliably when protected from sideways stress but allowed to move. Keeping the knee completely straight or immobilised for too long can lead to scar tissue and loss of bending or straightening. This is why most treatment plans include early, controlled movement in a hinged brace and physiotherapy from the first weeks.

Ongoing looseness

A grade 3 tear, especially one where the ligament pulls off the shin bone end, may heal in a lengthened position. The knee can then feel unstable during cutting or pivoting sports. Persistent looseness also puts more stress on a reconstructed ACL if both were injured. If symptoms continue after a full rehabilitation, surgical repair or reconstruction of the MCL may be considered.

Other problems to know about

• Calcification at the upper end of the ligament, known as Pellegrini-Stieda, which can cause a tender lump and is usually managed without surgery
• A missed combined injury, such as an ACL tear, meniscus tear or posteromedial corner injury, which can leave the knee unstable
• Repeat sprains if sport is resumed before strength recovers
• Ongoing inner knee pain that is actually from the meniscus or cartilage rather than the ligament

Reducing your risk

Get the injury properly graded, follow the brace and movement plan, complete the strength programme and return to sport gradually. If your knee is not improving as expected, Dr. Gelber at Aman Hospital in Doha can reassess it, check for associated injuries and arrange imaging if needed.
