mcl Flashcards
What is the anatomical location of the medial collateral ligament (MCL)?
The MCL runs from slightly above the medial femoral epicondyle to the medial aspect of the shaft of the tibia.
What other knee structures are often injured alongside a MCL sprain?
A MCL sprain often involves injury to other knee structures such as the ACL (anterior cruciate ligament) or medial meniscus.
What types of forces can lead to an MCL injury?
An MCL injury can be caused by a contact or noncontact mechanism, a fixed foot, tibial rotational injury associated with valgus force, and external tibial rotation.
Which sports are commonly associated with MCL injuries?
MCL injuries are often associated with activities such as football, skiing, and soccer.
What are the common signs and symptoms of a MCL injury?
Common signs and symptoms include knee pain, swelling, antalgic gait, decreased range of motion, and a feeling of instability.
How can the integrity of the MCL be assessed clinically?
A valgus stress test can be used to assess the integrity of the MCL.
What initial treatment is recommended for a MCL injury?
Initial treatment includes RICE (Rest, Ice, Compression, Elevation), NSAIDs (nonsteroidal anti-inflammatory drugs), and analgesics as needed.
What does conservative treatment for a MCL injury involve?
Conservative treatment involves decreasing inflammation, protecting the knee joint and ligament, range of motion exercises, and strengthening exercises as tolerated.
How do strengthening exercises progress in MCL rehabilitation?
Strengthening exercises gradually become more aggressive, and functional activities are introduced as tolerated.
Is surgery commonly required for MCL injuries?
Surgery is rarely required since the MCL is well vascularized.
