Torn Anterior Cruciate Ligament
Posterior Cruciate Ligament tear: Because this ligament stabilizes the knee with backward forces, the knee will drop back when fully ruptured. This is examined with the “Posterior Draw Test” by evaluating the distance the knee moves backward (posteriorly) compared to the non-effected knee.
Posterior Cruciate Ligament tear
“ACL Posterior Draw Test” is when you pull forward with the leg and hamstrings as lose as the patient can get, and evaluate the distance the tibia bone moves compared to the opposite non-effected knee.
Once the knee suffers blunt trauma in sports or everyday life, it is important to get ice applied to the knee joint ASAP to stop any swelling and pain. Depending on the level of injury, the tissue around the knee like the quads, hamstrings, gastrocnemius, and the ligaments may have torn and the knee will swell.
This is the knee capsule surrounding the knee joint. It is so thick, when the knee bleeds from a blunt trauma and torn tissue, you will not be able to see black and blue (aka ecchymosis) marking on the skin accept swelling.
Chondromalacia of the patella is when the cartilage behind the patella bone becomes torn and stringy. When the knee is flexed, the patella is pressed into the femoral groove and grinds on the choppy cartilage causing a spaghetti snapping sound. An imbalance and week support of the quadriceps is the cause of this and strength balance with leg exercises is needed.
