Great for medial bone on bone pain

I played basketball at the University of Texas and pounded my knees for 30 years. I have had a number of knee surgeries and am close to needing a total or partial knee. This brace takes pressure off of the medial side of the knee and is allowing me to stay relatively active, putting off another surgery hopefully for the next 3 years. Highly recommend this brace if you have pain on the inside of your knee.
