An LCL (Lateral Collateral Ligament) rupture is an injury to the ligament on the outside of the knee that connects the thighbone to the fibula. It can be a tear, sprain, or strain caused by a direct blow, a force that pushes the knee inward, or twisting motions, and often occurs during sports or accidents. Treatment depends on severity and can include conservative methods like rest, ice, bracing, and physical therapy, or surgery for more severe, complete tears.
Causes
A direct blow to the inside of the knee
A force that pushes the knee outward (varus stress)
Twisting, bending, or changing directions quickly
Sports injuries, such as from collisions or awkward landings
Car accidents
Symptoms
Pain on the outer side of the knee
Swelling and tenderness
A feeling of instability or weakness in the knee
Treatment
Conservative (for less severe injuries):
R.I.C.E.: Rest, Ice, Compression, and Elevation
Pain relief medication
Bracing and crutches to protect the knee
Physical therapy to restore flexibility, range of motion, and strength
