Treatment Options for Knee Cartilage Defects

As with most medical issues, treatment options start out conservative and work up to more invasive treatment options if they are ineffective. Initial treatment options include medication, physical therapy and injections. If those do not work, other treatment options include:

  • Microfracture – this treatment option involves helping the body to grow cartilage in the damaged area. This procedure involves penetrating the outer layer of the bone to expose where the bone marrow is located. These inner cells can then access the damaged area and promote cartilage growth and healing in the area. Microfracture is a fairly non-invasive surgery option that is safe and reliable and can be completed arthroscopically.
