Can the lateral collateral ligament heal itself?
Your LCL (lateral collateral ligament) is a vital band of tissue on the outside of your knee. Athletes are more likely to tear it, causing a lot of pain and other symptoms. LCL tears usually heal after three to 12 weeks, depending on severity. You have to take care of yourself, though.
What is collateral and what does it mean to me?
Strictly speaking, collateral is the asset or assets pledged by a borrower to back up a request for a loan. If the borrower gets the loan and fails to repay it, the lender has the right to seize the asset (i.e. collateral) to make up for the lost income. In the real world, collateral works like this:

Is the radial collateral ligament medial or lateral?
The medial (ulnar) collateral ligament (MCL) supports the ulnohumeral and radiohumeral joints medially, and is a fan-shaped structure. The lateral (radial) collateral ligament (LCL) also supports the ulnohumeral and radiohumeral joints, but laterally. It is more of a cord-like structure.
What does medial collateral ligament pain feel like?
MCL injuries hurt. Most people feel pain along the inside edge of the knee, and they also have swelling. You might hear a pop when the damage to the knee takes place, and your knee may lurch to the side. You may find it hard to walk, or feel like you can't put pressure on the leg with the hurt knee.
What is the fibular collateral ligament?
The fibular collateral ligament is one of the ligaments that make up the knee joint. Ligaments are bands of fibrous, durable tissue that connect and strengthen joints. They can be likened to rubber bands.
Which ligament is attached to the femur?
The fibular collateral ligament is attached to the femur (thigh bone) on one end, goes through the biceps femoris muscle, and attaches to the fibula (calf bone) on the other end. It collaborates with the tibial collateral ligament to form the system of bone, ligament, and tendon that is known as the knee joint.

What is the most common injury to the MCL?
The MCL is one of the most commonly injured ligaments of the knee. Valgus stress is the most common mechanism of injury. Injuries can be contact (a direct blow to the outer aspect of the lower thigh or upper leg) or non-contact (common in skiing). Contact injuries are usually more severe.
What is the valgus force on the knee?
A valgus force is then applied, a positive result of the knee in this position would be an increase in joint space medially.
What is the VST of MCL?
The VST assesses laxity of the MCL compared to the contralateral knee as a control. An increase in laxity and joint space usually distinguishes damage to the medical collateral ligament.
What are the two groups of ligaments that connect the thigh to the lower leg?
Knee ligaments are bands of tissue that connect your thigh bone to your lower leg bones. They can be classified into two main groups: collateral ligaments and cruciate ligaments . Sprained and torn knee ligaments are common, especially among athletes. They may be mild, requiring rest and simple treatment, to severe, requiring surgery.
What are the two ligaments that connect the femur to the tibia?
Cruciate ligaments: The two cruciate ligaments are inside your knee joint and connect your femur to your tibia. They cross each other to create an X. The anterior cruciate ligament (ACL) is located toward the front of the knee. The posterior cruciate ligament (PCL) is behind the ACL. The cruciate ligaments control the way your knee moves front to back.

The knee ligaments are bands of tissue that connect your thigh bone in your upper leg (femur) to your lower leg bones (tibia and fibula).
What are the collateral ligaments?
Collateral ligaments: The two collateral ligaments are like straps on each side of your knee. The medial collateral ligament (MCL) is on the inner side of your knee. It attaches the thigh bone (femur) to the shin bone (tibia). The lateral collateral ligament (LCL) is on the outer side of your knee. It connects your femur to your calf bone (fibula). The collateral ligaments prevent the knee from moving side to side too much.
What are the ligaments in the knee?
Knee ligaments are bands of tissue that connect the thigh bone in the upper leg to the lower leg bones. There are four major ligaments in the knee: ACL, PCL, MCL and LCL. Injuries to the knee ligaments are common, especially in athletes. A sprained knee can range from mild to severe. Talk to a healthcare provider if you have a severe knee injury or repeat injuries. Proper diagnosis and treatment can help prevent pain and future injuries.
What is a grade 1 knee injury?
Grade 1: A grade 1 injury to a knee ligament is a minor sprain. The ligament is overstretched or just slightly torn. With a grade 1 knee strain, you’ll have minimal pain, swelling or bruising. You’ll still be able to put weight on the affected leg and bend the knee.

Description
Attachments
- The superficial medial collateral ligament (sMCL) has one femoral and two tibial attachments.
- The femoral attachment is situated on the medial epicondyle.
- The proximal attachment 1. blends into semimembranosustendon and 2. distal attachment is at the posteromedial crest of the tibia.
Function
- The medial collateral ligament is recognised as being a primary static stabiliser of the kneeand assists in passively stabilising the joint. The superficial and deep ligaments each have a unique function, making the MCL the primary responder to valgus stress and a secondary restraint to rotational forces. 1. The sMCL, specifically the proximal divi...
Blood Supply
- Branches of the superior and inferior genicular arteries supply the MCL. The area near the bony insertions is more richly vascularized.
Nerves
- The MCL is innervated by the medial articular nerve, a branch of the saphenous nerve. 1. Innervation is greatest in the epiligament and near the insertions. 2. The ligament can perceive pain and process proprioception through specialized sensory mechanoreceptors like Ruffini endings, Pacinian corpuscles, Golgi receptors, and bare nerve endings. 3. Complete MCL tears w…
Clinical Relevance
- The MCL is one of the most commonly injured ligaments of the knee. 1. Valgus stress is the most common mechanism of injury. 2. Injuries can be contact (a direct blow to the outer aspect of the lower thigh or upper leg) or non-contact (common in skiing). Contact injuries are usually more severe. Injuries to the MCL can have detrimental effects to surrounding structures. 1. It is recog…
Assessment
- Assessment of the MCL is best within 20 to 30 minutes of injury before pain, swelling, and muscle spasms make examination difficult. The assessment includes palpation and a special test, the valgus stress test VST 1. Palpation The anterior aspect of the ligament can be palpated moving vertically, roughly midway along the medial joint line. Focal tenderness indicates an MCL injury. …
