Offering an Early Treatment Option for Your Patients

The Subchondroplasty Procedure (SCP) is a minimally-invasive, fluoroscopically-assisted intervention that targets and fills subchondral bone defects, often called Bone Marrow Lesions (BML) with AccuFill® Bone Substitute Material. 

AccuFill BSM is an engineered calcium phosphate mineral compound, a bone graft substitute, that mimics the properties of cancellous bone, resorbs and is replaced with new bone during the healing process.1,2

The SCP Procedure is usually performed along with arthroscopy for visualization and treatment of findings inside the joint. In some cases, an open or mini-open procedure is necessary for access to the defect.

Philosophies

  • Early Intervention

Application

  • Knee, Foot & Ankle, Hip, Shoulder

Peer-reviewed data demonstrate sustained pain reduction, improved function and quality of life after the SCP Procedure.3,4

The minimally-invasive SCP procedure is usually performed along with arthroscopy for visualization and treatment of findings inside the joint. In some cases, an open or mini-open procedure is necessary for access to the defect.

Bone defects are filled with AccuFill Bone Substitute Material (BSM), a proprietary, flowable, biomimetic bone substitute.1,2

AccuFill BSM is available in prefilled (PF) mixing and saline syringes. The prefilled kit includes all components to hydrate and mix AccuFill BSM in a closed mixing system. 

The SCP procedure fills bone defects with AccuFill BSM, a truly-injectable bone substitute material

AccuFill PF BSM Kit

For consistent, reproducible hydration and mixing of AccuFill Bone Substitute Material (BSM). Fewer procedural steps with user-friendly design and technique.

AccuFill BSM

Nanocrystalline*, highly porous injectable calcium phosphate (CaP) that mimics the chemical composition and crystalline structure of natural human bone mineral.1,2

 

Injected AccuFill BSM

An engineered calcium phosphate compound that flows readily to fill subchondral bone defects, the crystalizes and sets in an isothermic reaction at 37 degrees C to form a nanocrystalline,* microporous scaffold in the bone. AccuFill BSM is replaced with new bone during the healing process. 

AccuMix Mixing System

Hydrates and mixes AccuFill BSM 

Closed mixing system 

Controlled, consistent mixing 

Closed transfer to injection syringes – No loss of mix 

User-friendly design, technique 

AccuPort Delivery Cannulas

2 components: cannula + stylus – Stylus locks to cannula hub. Trocar-tip for cutting ability. Insert with OR wire driver. 2 sizes. 11 gauge cannula . Side or end-delivery . 15-gauge cannula. End-delivery. Smaller lumen and shorter length is designed to be a  good choice for use in the smaller bones of the midfoot and forefoot

*The grain size of the hydroxyapatite (HA) crystals that form as part of the amorphous and crystalline mixture of calcium phosphate sets are on the nanometer scale. The size of the crystalline structures were measured by X-ray diffraction to be less than 100 nanometers.

Benefits

Application

  • Treats chronic, symptomatic, subchondral bone defects which are the primary cause of joint pain, not the intra-articular tissue.5,6

Treatment

  • Proprietary minimally-invasive, joint preserving injection of AccuFill BSM which is replaced with new bone during the healing process.1,2
  • Usually performed along with arthroscopy to aid in visualization, the SCP procedure does not inhibit the treatment of other findings inside the joint when performed along with arthroscopy.
  • Typically, an outpatient procedure enabling patients to generally return home the same day.

Results

  • AccuFill BSM sets hard and remodels into new bone during the healing process.1,2
  • Peer-reviewed data demonstrate sustained pain reduction, improved function and quality of life.3,4
  • SCP Procedure does not preclude future procedures. Should it become necessary, future surgery is still an option.
