Is the Subchondroplasty (SCP knee procedure right for you?

Does this describe your pain:

  • 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

The SCP Subchondroplasty procedure has been shown to resolve subchondral bone defects as well as the associated edema, which is a known source of chronic knee pain.



  • Chronic inflammation of subchondral bone
  • White signal on fat supressed T2 MRI
  • Associated with: – Subchondral defects – Insufficiency Fractures – Stress Fractures
  • Often below Cartilage Defect
  • Area of weakened load bearing capacity
  • A strong predictor of pain and loss of function
  • Risk factor for structural deterioration
  • A cause of limited outcomes from arthroscopic intervention

You may have bone defects called chronic bone marrow lesions (BMLs). Chronic BMLs may heal without a treatment but should be evaluated by your physician. BMLs can only be seen on MRI and a doctor must examine you to see if you have this condition.



The knee is one of the strongest joints in the body and takes a large amount of impact during almost all physical activities. The knee joint includes the end of the femur (thigh bone), top of the tibia (shin bone) and patella (knee cap). Movement of the joint is regulated by surrounding muscles and ligaments which control bending, extension, and rotation. The meniscus, cartilage, and synovium provide shock absorption and fluid movement between the bones.

Subchondroplasty is the minimally invasive repair of subchondral defects associated with chronic bone marrow edema.



  • Option for patient wanting alternative to TKR
  • Treatment when HA & others have failed
  • Addition to Arthroscopy
  • Treats diseased bone, not cartilage

You should discuss knee treatment options and ask your surgeon any questions you have so that you will make the best decision.

It is important to fully understand the recovery time, risks and benefits with this minimally invasive treatment before making a decision to treat your knee.




Following surgery, you can put weight on your leg as tolerated (unless otherwise instructed). Walking may be painful and it is typically necessary to use a cane, crutches, or walker for a short period of time after surgery.
You will be given a prescription for outpatient physical therapy. You should start therapy within a few weeks following surgery.
Some patients will report significant pain for 1 -2 days immediately following surgery. To control this pain:
  • Use pain medicine as prescribed by your doctor
  • Elevate your leg above the level of your heart
  • Apply ice to your knee for 15 minutes 3 or 4 times per day
If a sterile dressing was applied to the area, it may be removed within 1–2 days following surgery.
Any adhesive strips under the dressing, should not be removed. However, if they wash off when showering, it is not a problem.
You may shower the day after surgery when the dressing is removed. However, do not soak in a tub, pool or any other body of water for two weeks after surgery.
If you have signs of infection, which include fever of 101 degrees or greater, flu-like symptoms, redness, swelling, or excessive pain, please call your surgeon immediately.
