Medial Collateral Ligament Injuries
The medial collateral ligament is one of four major ligaments of the knee. The medial collateral ligament extends from the medial epicondyle of the femur to below the medial condyle of the tibia. The MCL is a static stabilizer composed of superficial (primary) and deep (secondary) portions that are restraints to valgus stress. The superficial MCL is the primary restraint to valgus stress. The proximal attachment is located on the posterior aspect of the medial femoral condyle. The distal attachment is located at the metaphyseal region of the tibia, about 5cm distal to the joint, lying beneath the pes anserinus. The Deep MCL assists as a secondary restraint to valgus stress. The Deep MCL inserts directly into the edge of the tibial plateau and meniscus. It may be separated from the superficial layer by a bursa. The joined tendons of the Sartorius, gracilis, and semitendinosus muscles cross on top of the lower part of the MCL. The pes anserine bursa is located anterior to the insertion of the medial collateral ligament into the tibia. The MCL’s primary function is to be a restraint to valgus stress. The MCL is the most commonly injured ligament of the knee. The typical mechanism of injury of the MCL is due to a valgus and external rotation force. A direct blow to the knee usually causes a complete rupture of the MCL. Rupture may occur proximally or distally. Tears of the proximal MCL have a greater healing rate; however, tears of the distal MCL may not heal well (similar to a Stener lesion of the thumb). Injury to the ACL comprise up to 95% of associated injuries. Rupture of the ACL causes anterolateral rotatory instability. The majority of MCL injuries that are associated with ACL injuries are Grade III complete ruptures, no end point with valgus stress at 30° and 0° of knee flexion. Up to 5% of isolated MCL injuries are associated with meniscal tears. Not a common injury. MCL sprains are classified into three different grades. Grade I injuries are a sprain or stretching injury. Grade II injuries consist of a partial tear of the MCL. Grade III tears are a complete tear of the ligament with no end point with valgus stress at 30° of knee flexion.
A medial collateral ligament injury will typically create a “popping” sensation. Pain and tenderness is usually found higher than the joint line. During the physical examination, tenderness will be discovered along the medial aspect of the knee. A positive valgus stress test at 30° of knee flexion indicates injury to the superficial MCL. Opening around 1 cm indicates a Grade III complete tear of the MCL. A positive valgus stress test at 0° of knee extension indicates posteromedial capsule or cruciate ligament injury in addition to MCL injury (combined injury). The physician should always evaluate for other injuries to the ACL, PCL, or medial meniscal tear. Radiographs are usually normal; however, they may show calcification at the medial femoral site (Pellegrini-Stieda Syndrome). Calcification due to chronic MCL deficiency at the medial femoral insertion site. A pediatric patient with a knee injury and a suspected salter fracture should have stress view x-rays performed to rule out a growth plate injury. Growth plates are weaker than ligaments and it may be more beneficial to have an MRI performed rather than stress view x-rays. An MRI is the study of choice as it identifies the location and extent of the MCL injury.
Treatment typically consists of NSAIDs, rest, and therapy. A minor sprain of the MCL will require therapy with a return to play in about a week. A brace may be used if the injury is classified as a Grade II and they will return to play in about 2-4 weeks. With Grade III injuries, there will be a return to play in about 6-8 weeks. Surgery is performed in Grade III injuries with a multiple ligament injury, especially with distal avulsion fractures. If there is chronic instability with opening in full extension, a reconstruction should be performed. An additional arthroscopy may be needed to rule out associated injuries. In combined MCL and ACL injuries, usually surgery for the ACL is delayed until the MCL heals (up to eight weeks) and then an ACL brace should be used. Complications consist of stiffness and loss of motion. Laxity is associated with distal MCL injuries. Functional bracing may reduce an MCL injury in football players, particularly with interior linemen.

My goodness, this was super succinct, simply explained, and straight to the point. Question: I am 60 years young, a former dancer and footballer, had an injury years ago (in 1976 USA high school football), they did not have pinhole surgery back then) and have had "knee particle clean out" over the past 15-years. I also have right knee valgus. There is no pain although instability when running occurs. I have 90% flexion and nearly 100% extension on the knee. My big problem is it's tough to run without instability and my left upper hip (right in the connective area) hurts when standing or walking too long. Now I have a choice of (1) ACL & MCL reconstruction; (2) knee replacement; (3) "conservative management". I plan to continue to run and sprint straight ahead (no more agility sid-by-side pivot and cut). What would you suggest? I know it is limited information but, is surgery necessary? The recovery time freaks me out. Thanks!

[@anthonyhou9374]

Hi, I don't know what you did, but No never go for the knee replacement option! Go for the ACL and MCL reconstruction + physiotherapy and you'll feel you are a new person!!

[@tadbubs]

@@anthonyhou9374 Thank you. I had the osteotamy and MCL completed 10-months ago. Now I am working my way back to full strength. Oddly, I'm having a challenge raising back up on my toes (both sides) and a bit of lower back stiffness and pain (just near both piriformis muscle area)

[@anthonyhou9374]

@@tadbubs @Bill Calhoun I wish you a well and complete recovery brother! Those are typical symptoms after a knee surgery and the stifness located near your lower back won't last if you are someone that isn't scared of moving...! I pray for you brother🤲🙏

@@anthonyhou9374 Thank God! It scared the beezwax out of me.

[@Satnam7275]

I am 50 and recently had a bike accident and fell on the ground on my back. I have been detected with complete detachment of MCL at Tibial site in a MRI report. One Doc suggested surgery and another with a conservative treatment of knee brace. Will my MCL heal naturally by such conservative treatment? Please advise Sir.

i have a grade 2 tear how long it will take for full recovery . can i able to play sports actively again

[@Will-zx9uz]

I have a grade 2, it’s been 5 weeks and I’m nowhere near healed enough to return to sport. I’m still wearing a brace, and still feel pain under even minimal valgus stress. This video states 2-4 weeks but from my experience that is way off.

[@gauravdevkar6696]

Please gyes, i have been mcl sprain grade 2 as well minuscus horizontal tear, how time its take and please suggest me actuall traetment. Share your experience
