Articular cartilage covers the ends of bones in joints throughout the body. Normal cartilage is smooth allowing easy gliding of the joint. When cartilage is injured, the smooth surface can become rough. Cartilage is unable to heal or replace itself. Occasionally the cartilage injury is severe and there is complete loss of cartilage resulting in exposed bone. Sometimes called OATS or Mosaicplasty osteochondral grafting is a method of treating cartilage injuries that expose underlying bone. Osteochondral graftsreplace both the articular cartilage on the surface and the underlying bone. The tissue can come from other parts (typically knee) of the patient’s body (called osteochondral autograft) or from a tissue donor (osteochondral allograft). These techniques are commonly used in the knee but can be used in other joints.
The injured area of cartilage is identified and a core of the injured cartilage and the underlying bone is removed in a method similar to coring an apple. A replacement core made up of cartilage and bone from another site in the knee (autograft) or a tissue donor knee (allograft) is then made to fit into the hole. The replacement core is gently tapped into place until it lines up with the surrounding tissue. It acts as a pressfit. No screws or other devices are typically needed to hold the replacement core in place since it fits tightly. Frequently it can be performed all arthroscopically.
Patients can usually start to bear weight within 4-6 weeks of surgery. Activity is gradually increased with return to sport typically occurring after 6-9 months.
Patients often recover very well from both of these procedures. One advantage of these techniques is the ability to replace both cartilage and bone with similar tissue. There are limitations to the amount of tissue that can be taken from within a patient’s own knee so larger areas of cartilage loss may not be best for this approach. A potential concern with the use of donor tissue is the very low risk of disease transmission (like a blood transfusion). Although these techniques are new to have data on how well patients recover in the long term, it has been seen that these patients frequently do very well.

Not enough time to exercise some days. This 7 minute workout can help. It can be done anywhere and does not require any special equipment. You can do it in a hotel room on the road. I have found it to be very helpful. Read about it HERE. There is an app you can download and keep on your phone that times the exercises and workout. The Johnson and Johnson 7 minute workout.

Kevin Durant tore his MCL and sustained a bone bruise. What does that mean for him and the Golden State Warriors? The MCL or medial collateral ligament is a structure that runs from the femur (thigh bone) to the tibia (leg bone) on the inside of the knee and provides side to side stability with sports and normal life activities. It is the most commonly injured ligament in the knee. Fortunately the injuries typically heal on their own with rest and protection of the damaged ligament. Their are 3 grades of tears. By report he sustained a Grade 2 sprain.As seen below Grade 1 sprains are mild stretches without ligament disruption. A Grade 2 is a partial tearing and a Grade 3 is a complete tear. With a Grade 2 tear it typically is 3-4 weeks for recovery for a basketball player. He will likely return in a brace to help protect the healing ligament and prevent additional injury. He also sustained a bone bruise which may add some time. Read my review of bone bruises HERE. With a little luck he could be back before the playoffs.
