What is Subchondroplasty®?

The Subchondroplasty® (SCP®) procedure is a minimally invasive surgery designed to access and treat bone defects associated with chronic bone marrow lesions (BMLs) by filling them with a biomimetic bone substitute material (BSM).

SCP® leads to healing as the BSM is resorbed and replaced with new, healthy bone.

BML Diagnosis

BMLs can only be seen on certain MRI sequences, where they are marked by edmatous or "inflamed" areas that have been shown to represent a healing response surrounding a microscopic insufficiency fracture within the subchondral bone.

The SCP® Procedure

The SCP® procedure is based on accepted methods of fracture healing, which are applied to defects associated with BMLs in the subchondral bone.

It is performed either alone or in conjunction with other arthroscopic treatments.

The SCP® procedure is typically performed in an out-patient setting, meaning patients usually return home the same day.


Is Subchondroplasty® Right for Me?

Does this describe you?

  • I have experienced symptomatic knee pain for 3+ months
  • I have increasing discomfort when walking or standing
  • I have seen limited benefits from NSAIDs, bracing, injections or physical therapy
  • My symptoms returned after an arthroscopy

You may have bone defects called chronic bone marrow lesions (BMLs). Many surgeons believe that chronic BMLs will not heal without a treatment such as the Subchondroplasty® procedure.

BMLs can only be seen on MRI. Only your doctor can tell if you have this condition.

The SCP® procedure is not recommended for patients with BMI > 40 or patients with severe malalignment of the joint.

You should discuss treatment options and possible risks with your surgeon. Please ask your surgeon any questions you have so that you will make the best decision. It is important to fully understand the risks and benefits any treatment before making a decision.


Why Choose Subchondroplasty®?

Bone Marrow Lesions (BMLs) are present in many patients with knee pain and osteoarthritis.

BMLs have been shown to be:

  • The strongest predictor of pain in knee osteoarthritis patients.
  • One of the strongest long-term predictors of Total Knee Replacement.

Patients with BMLs:

  • Show decreased function and faster cartilage destruction.
  • Have reduced benefits from arthroscopy alone.
  • Are approximately 9 times more likely to progress rapidly to a Total Knee Replacement.

Increasingly, orthopaedic surgeons recognize that chronic BMLs will not heal without treatment.

What you need to know about the SCP® procedure:

  • Utilizes a minimally invasive technique
  • Performed in a outpatient setting
  • Requires a short rehabilitation period
  • Future treatment options remain open
