An Alternative to Knee Replacement: The BioKnee

Heal biologically. If you are looking for an alternative to a total knee replacement, consider our BioKnee program which rebuilds knees without the use of artificial implants.

The BioKnee® program combines Dr. Kevin Stone's most innovative surgical procedures to create a revolutionary treatment for arthritis. The program has permitted hundreds of people with moderate to severe arthritis to stay active and delay or avoid a total knee replacement. 

What is a BioKnee®?

A BioKnee is an alternative to an artificial knee replacement. It combines three key procedures that rebuild, regenerate, or biologically replace the damaged parts of the knee using donor tissues, a patient’s own stem cells, and growth factors. The Bioknee program uses the procedures below individually or in combination to biologically replace your injured joint.

Articular Cartilage Regeneration

With a BioKnee, we first repair the articular cartilage, the white shiny surface that covers the ends of the bone. We’ve been doing this for over 25 years with a technique called Articular Cartilage Paste Grafting, which is clinically proven to promote the regrowth of cartilage inside the knee. In a single-step procedure, we take stem cells from your own bone marrow and mix them with harvested cartilage cells to form a paste. When the paste is packed into the damaged area of the joint, it is able to regrow cartilage repair tissue.

Meniscus Repair, Regeneration, or Replacement

Another BioKnee procedure repairs, regenerates, or replaces the meniscus, the shock absorber in the knee joint. A damaged or missing meniscus leads to increased forces across the knee and causes arthritis. We have developed new techniques to repair the meniscus and when we can’t repair the meniscus, we replace it with a donor meniscus in a procedure called a Meniscus Transplant.

Dr. Stone pioneered the Meniscus Transplant technique and has now performed over 500 meniscus transplants in patients since 1995. The Stone Clinic runs the Meniscus Transplant Center, one of the few centers in the world dedicated to the diagnosis, surgical implantation and rehabilitation of meniscus transplant patients.

Ligament Reconstruction

Another BioKnee solution is to fix damaged ligaments in order to properly stabilize the knee and prevent uneven wear on the articular cartilage bearing surface caused by loose, unstable knee joints. We are able to repair, reconstruct, or replace these ligaments often using donor tissue.
