Posterior Cruciate Ligament (PCL) is a thick structure which is present in the backside of the knee connecting the thighbone to the shinbone, there by stabilizing the knee joint. It prevents the shin bone from displacing backwards during different activities. The PCL is generally larger and stronger than the Anterior Cruciate Ligament. Even then, the PCL can get damaged due to trauma or injury (direct or indirect), which can cause disability to the knee.

However Grade III and IV PCL tears need surgical intervention. With Modern technology and improvisation in surgical techniques, these injuries are routinely treated by Key-Hole technology without opening the joint. There are multiple advantages to this technique such as a) less blood loss, b) less pain, c) early recovery, d) less tissue damage, e) lesser chance of infection, f) more cosmetic,etc. After surgery patient has to undergo physiotherapy for three to six months and after which he or she will be able to do all activities which they were doing before the injury.

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.
