Subchondroplasty Procedure

by David Rhoads M.D. on 07/30/14

Does this describe you?
-- Experienced symptomatic knee pain for 3+ months?
-- Have increasing discomfort when walking or standing?
-- Have seen limited benefits from medications, bracing, injections, or physical therapy?
-- Symptoms have returned after knee arthroscopy?

If you have answered yes to the questions above, you may be a candidate for Subchondroplasty procedure. 

Drs. David Rhoads and Brad Dunkin are among the first in Louisville area introducing Subchondroplasty, a new minimally invasive procedure designed to delay the need for a total knee replacement.  It is a percutaneous outpatient intervention that addresses the defects associated with subchondral bone marrow edema (BME). BMEs are related to stress fractures or micro-fractures and are diagnosed using MRI. Left untreated, these defects have been shown to lead to cartilage degeneration, limited function, pain and greater risk for joint deterioration.  Subchondroplasty is currently the only treatment that specifically targets bone marrow lesions, the key underlying cause of knee pain.  The procedure is based upon accepted methods of fracture healing and involves injecting a specialized bone substitute into the defect.  As the defect heals, the bone substitute is absorbed and replaced with the individual's new healthy bone.


In this minimally invasive, arthroscopically-assisted procedure, navigation instruments are used to inject a specialized bone void filler to treat the bone defect and begin the healing process, without violating the joint. Since its introduction in November 2010, more than 1,500 Subchondroplasty procedures have been completed.  



To see if you are a candidate for Subchondroplasty, please call our office and make an appointment with Drs. David Rhoads or Brad Dunkin.  There are many options, even if you are not a candidate for Subchondroplasty, there are usually other treatment options available.
