You have tear in medial meniscus and degenerative joint changes. Usually oblique and horizontal tears of the medial meniscus involve the white portion of the medial meniscus and are not fully repairable with conservative treatments. The tear in the red zone of medial meniscus will heal with rest, elevation, ice and compression, followed by physiotherapy. However, since big tears usually do not repair fully, partial or complete removal of meniscus (meniscectomy) is performed. If conservative treatment to reduce joint effusion does not help, you may need knee replacement. Please discuss with your doctor. Take care!

I agree with Dr. Mathur's assessment. I would like to add that the menisectomy she mentions can all be done arthroscopically. We do them in same day surgery. Best of luck! jd1963
