What is the largest joint in our body? Answer: The Knee. The knee is the connecting point of a total of three bones in our legs: the lower end of the thigh bone or the femur, the upper end of the shinbone or the tibia, and the knee cap or the patella. Other parts of the knee are the cartilage or the shock absorbing cushions in between muscles, the tendons or the cords connecting muscles to bones, and the ligament or the bands connecting our bones to other bones. Any damage to all of these parts are accounted for by a Knee physical therapy, and just the ligament alone is so vulnerable to pulling, stretching and tearing, and with each knee having four major supporting ligaments: the anterior cruciate ligament or ACL at the center of knee, the posterior cruciate ligament or PCL also at the center, the lateral collateral ligament or LCL at the outer knee, and the medial collateral ligament or MCL at the inner knee – Oh the pains of a sprain! and much more other knee ailments. Knee physical therapy deals with damages to all these bones and parts altogether – so what better reason to take care of it!
