Most patients are able to return to some physical activity after six to eight weeks, but full recovery after cartilage repair surgery can take anywhere from three to six months. Diagnosis of these problems can be used with standing x-rays which may show joint space narrowing, or the use of a high-quality MRI scan. Chondral fissures are a type of chondral injury, more accurately cracks, cleavages or crevices of cartilage extending from the articular surface to the deeper We have noticed that certain types of patellar instability result in a bulge (or protrusion) of the distal medial facet of the patella which can hinder recentering in the trochlear groove.

For patients who choose not to want surgery and who have more extensive chondromalacia, the use of an unloader brace to take the stress off a malaligned joint which has the weightbearing fall through the cartilage defect, or the use of further injections, such as viscosupplementation with hyaluronic acid or PRP may be indicated. What does medial extrusion mean? Right Knee Surgery After Auto Bicycle Accident, Medical Second Opinion Service MRI/X-ray Review. The healing process for a patella fracture can vary, depending on the severity of your break and whether you had surgery or not. A patient with a symptomatic chondral defect undergoes the arthroscopic procedure seen in Figure A. 2. Come back the next day and it's still there, no healing. As you recover from surgery, the cartilage cells regenerate, forming new tissue to replace worn-out cartilage. An arthroscopic picture taken during diagnostic arthroscopy is shown in Figure A. Small pieces of the articular cartilage can break off and float around in the knee as loose bodies, causing locking, catching and/or swelling. Other means can include growing ones cells and replacing it, called a MACI procedure, or having a fresh donor graft from a recently deceased young donor and replacing the whole bone and cartilage unit, called a fresh osteoarticular allograft. $35 for typical specialist consult vs. $120 for a local appointment.

Dr. Robert F. LaPrade operated on my right knee in May of 2010. The fact that we rely on motion of the opposing surface to provide nourishment for cartilage is the principle behind early motion after cartilage surgeries and the use of a continuous passive motion machine (CPM).
