Lateral Collateral Ligament (LCL) is one of the major ligaments of the knee joint. It is present on the outer aspect of the knee and connects the thighbone or to the leg bone, adding to stability of the knee. LCL can get injured by a contact injury like a hit or a blow during a physical activity or an accident, or it may suffer from a non-contact injury like over extension and over stress.
Examination of the knee by the specialist usually makes the diagnosis obvious. X-ray of the knee is taken to rule out any underlying bony injury. Further a MRI scanning is mandatory to know the extent of injury including the involvement of other ligament structures.
Like any other knee injury the type of treatment for a LCL tear will depend on the severity of the injury. The basic treatment for non complex injury includes:
In case of minor injury, 3 to 6 weeks of rest and protective bracing is advised to the patient. Following which the patient is taken through a graded physical therapy program, to bring back the normal movement of the knee and to get the original strength on the muscles around the knee.
For complex injuries surgery in the form of ligament repair or reconstruction might be necessary. Generally in the complex scenario the LCL tear affects the other ligaments as well. Hence treatment is planned case by case basis depending on the injury pattern. Grafts are taken from patients own tissue and are reconstructed. After a period of rest and physiotherapy, patient will be able to lead a normal active life.

My mother in law had her second knee replacement surgery and she is walking fine now,and Dr. Raj Kanna sir is very good at explaining the do's and don't s to the patient.
I had meniscus tear on my right knee. Thanks to Dr. Rajkanna. He explained the exact details of the status of injury, procedure to be done and do's & don't s after surgery. He didn't demand much as fees. I am feeling good like before the occurrance of injury. I would recommend him for Ortho related problems.
