I feel coming out of kettlebell aerobics last October 2013. I fell on a cement parking stop and my right knee to the blow. It hurt and the ER xray showed nothing broken and perhaps a bruise. I was in pain for about two weeks and kept ice on it for the immediate 24-48 hours. A bruise came through and the only pain I had was kneeling on it. After the first week I forgot about the injury and knelt down to pick something up and the pain was unbelievable along with a gush of warm liquid feeling. Since then I have a funny sensation as if I had a scar like after an operation. I feel no pain in the bone or joint during walking or jogging or exercising. However I do feel pain kneeling on it. It swells and if I bump my knee while doing anything I feel a sharp pain and tingling. I went to an ortho doctor and he stated I had nerve damage. I saw a doctor an had a full EMG done and it was reported normal and healthy. I had an MRI done and it states No occult fractures are seen within ght e osseous structurs of the right knee. No significant osseous contusion are visualized. The anterior andposterior cruciate ligaments are intact. No definitive tears are seen with in the medial or lateral menisci. There is a myxoid degeneration in the posterior horn of the medial meniscus. There is mild narrowing of the medial compartment. No abnormal signal is seen within the distal quadriceps or patellar tendons. Medial collateral ligman is intact. No abnormal signal is seen in the iliotibibial band fibulocollateral ligament or biceps femoris tendon. The medial and lateral retinacula are intact. There is minimal edema seen anterior to the patella. No abnormal signal is seen in the posterior patellar cartilage. So what does this mean? Will I need to surgery?
