Summit Bone and Joint performs knee replacement using the Ascent® knee system. The technique of knee replacement uses implants to resurface damaged bone and cartilage at the end of the thighbone and the top of the shinbone. Total knee implants are designed to enable you to regain function in your knee. Stair climbing, rising from a seat, and walking can be restored, while pain can be significantly decreased or completely eliminated. In SBJ's hands, the Ascent® knee can help you return to a more active lifestyle.
