Cartilage, or chondral, damage is known as a lesion and can range from a soft spot on the cartilage (Grade I lesion) or a small tear in the top layer to an extensive tear that extends all the way to the bone (Grade IV or full-thickness lesion).
A Bakers cyst, or popliteal cyst, is a bulging lump behind your knee. Inside the lump is a sac filled with fluid. The cyst is caused by fluid buildup in your knee joint. This can happen if you have a knee injury, such as a cartilage tear. Osteoarthritis or rheumatoid arthritis can also cause an abnormal buildup of joint fluid. Common signs and symptoms: 1  A lump or swelling in the back of your knee when you stand or walk. 2  Knee swelling that goes away when you bend your knee. 3  Knee pain. 4  Stiffness or tightness in your knee that may get worse with movement.
