Biologic Solutions


Arthrosurface offers multiple Biological Solutions as early treatment options for joint pain & disease:

  • NanoFx® – A Microfracture Procedure

NanoFx® Microfracture

For patients who have the beginning stages of arthritis and/or cartilage damage, Arthrosurface® offers a device for microfracture and marrow stimulation, The NanoFx® (Nanofracture). The system provides a smaller, deeper and better solution than a standard microfracture operation. The NanoFx handle is available with a 15° angle and as an A-Curve, which is specifically designed for hard to access Ankle Lesions. During a NanoFx® procedure, a surgeon uses a needle to create holes in the exposed lesion (bone) that will cause bleeding. This enables new cartilage to develop, which will grow and fill the lesion, creating a new joint surface. This procedure has been proven to create smaller and deeper cell channels than a standard microfracture technique, therefore stimulating more bone marrow and achieving better results. Because NanoFx® creates channels that are consistently 9mm deep yet on 1mm in diameter it doesn’t disrupt or weaken the bone but instead it allows the marrow to flow and clot. Over time the clot stabilizes and turns into new tissue that fills the cartilage gap on your knee, shoulder or ankle.

  • Doesn’t damage the underlying bone
  • More holes provides increased marrow flow to the defect site
  • Better tissue quality with pain relief
  • Functional improvement and greater durability
  • Reduced osteophyte formation (bone bumps)

When the body sustains damage from either a trauma, disease or simple wear and tear, it normally results in the formation of a lesion or cartilage gap on your joint surface. The patients most likely to benefit from the Arthrosurface NanoFx® (nanofracture) procedure are the same as those targeted for any microfracture technique. You may be a candidate if:

  • Your cartilage lesion is smaller than 1.5 cm
  • You are in the early stages of cartilage damage
  • There is limited areas of cartilage damage
  • You are active and cannot play sports because of symptoms
  • You are probably younger than 40 years old
  • You have pain after long walks, climbing stairs or while playing pivot or impact sports

Do not delay seeking professional medical advice or disregard professional medical advice because of something you have read in this brochure.

knee painThe rehab for microfracture procedures can be lengthy and involve minimal weight bearing for weeks. A full return to activity can be expected around nine to twelve months post surgery. Mobilization begins immediately after surgery. Weight bearing with crutches is typically recommended for up to eight weeks. Patients typically begin stationary biking without resistance and a water exercise program at two to four weeks after the microfracture procedure, depending on the size and position of the lesion. Patients usually progress to full weightbearing after about 8 weeks and begin more vigorous biking with increasing resistance. Depending on the clinical examination, size of the patient, the sport, and the size of the lesion, it is usually recommended that patients do not return to sports that involve pivoting, running, and jumping until at least 4 to 9 months after microfracture surgery.
