MCL Tear: Inner Knee Ligament Injury Treatment in Doha

What is the MCL?

The medial collateral ligament (MCL) is a broad, flat band on the inner side of the knee. It runs from the inner thigh bone (femur) to the upper shin bone (tibia) and stops the knee bending inwards, the knock-kneed direction. It also helps control rotation together with the ACL.

The MCL is the most commonly injured ligament in the knee. Unlike the ACL, it lies outside the joint and has a rich blood supply, which is why it heals so well in most people.

Grades of MCL injury

• Grade I: the fibres are stretched, with tenderness but no looseness
• Grade II: a partial tear, with some opening of the inner knee on testing but a firm end point
• Grade III: a complete tear, with the inner knee opening clearly under stress

The grade, and where along the ligament the tear sits, guide treatment and recovery time. Tears at the shin bone end sometimes behave differently from those near the thigh bone and are watched more closely.

Symptoms, in patients' own words

• "It hurts on the inside of my knee when I touch it"
• "My knee got pushed inwards and I felt something pull"
• Swelling along the inner knee, sometimes with bruising
• Pain when straightening the knee fully or twisting
• A feeling that the knee might buckle sideways, in higher grades

Many people can walk soon after an MCL sprain, which can make it easy to underestimate. Large swelling inside the joint within hours suggests that the ACL or meniscus may also be injured.

Causes and who gets it

The typical cause is a blow to the outside of the knee that forces it inwards, such as a sliding tackle in football or a collision in basketball. It also happens without contact, when the foot is planted and the body twists, a common pattern on padel and squash courts, and in skiers on holiday.

In Qatar we see MCL injuries in footballers on grass and artificial pitches, padel players, wrestlers and martial artists, and in falls at work. An MCL injury may occur alongside an ACL tear, especially after a twisting injury with a pop.

Diagnosis

Dr. Gelber examines the knee with valgus stress testing in slight bend and in full extension. Opening in full extension suggests a more serious injury involving other structures. He also checks the ACL, meniscus and kneecap, since combined injuries change the plan.

An MRI scan is useful when the grade is unclear, when swelling is significant, or when another injury is suspected. X-rays exclude a fracture or a bony avulsion.

Treatment

Isolated grade I and II MCL injuries are treated without surgery. Many grade III tears also heal well with the same approach. Treatment usually includes:

• Ice, compression and relative rest in the first days
• A hinged knee brace that blocks sideways stress while allowing bending
• Early movement, so the knee does not stiffen
• Progressive strengthening of the quadriceps, hamstrings and hip muscles
• Sport-specific drills before a return to football or padel

Surgery is considered when the MCL is torn together with the ACL or other ligaments and the knee remains loose, when the ligament has pulled off the bone and become trapped, or when instability persists after a full course of rehabilitation. Options include repair, or reconstruction with a tendon graft.

Recovery and when to see a specialist in Doha

As a conventional guide, a grade I sprain often settles in two to four weeks, a grade II in four to eight weeks, and a grade III in eight to twelve weeks or longer. Return to sport depends on strength, a full range of motion and confidence on cutting drills, not on the calendar alone.

Book an assessment if the knee swelled quickly, feels unstable, cannot fully straighten, or is not improving after two to three weeks. Dr. Gelber sees MCL injuries at Aman Hospital in Doha and checks for associated ACL and meniscus damage before agreeing a plan.
