Arthrosurface Solutions

The HemiCAP® technology was designed for patients who want to continue working, keep their active lifestyles and have a need for joint preserving treatments and as an alternative to total joint replacement. Many of these patients are looking for a treatment option that “bridges the gap” between biological treatments and total joint replacements.

joint replacementResurfacing a joint with a HemiCAP® implant is a much less destructive procedure than a total joint replacement. The idea behind the HemiCAP® system is to prevent further damage to the joint while maintaining the patient’s native anatomy and motion. The HemiCAP® simply places a smooth surface in the place where the cartilage has worn away — imagine a filling for a tooth cavity. It is a contoured surface that goes over the area of damaged cartilage and is designed to protect the remaining (healthy) cartilage in the joint.Instead of a one piece implant with a stem built in, the HemiCAP® is two components that consist of a cap and screw that mate together via taper lock. The HemiCAP® screw system has been a stable construct with no reported loosening.

The HemiCAP® is used in the hip to remove the damaged cartilage and dead bone exposing the healthy bone underneath. The post provides fixation and the HemiCAP® provides a new articular surface. This is designed to alleviate the pain, remove the dead bone and reduce the opportunity for collapse. Because most of these patients are 30-50 years, it postpones the need for a total hip replacement. The Hip HemiCAP® is useful in 2 types of hip pathologies: pipkin fractures and avascular necrosis (osteonecrosis).

How is the HemiCAP® different than other existing devices?

  • Little to no activity restrictions making the Arthrosurface implants an active alternative to hip replacementknee joint
  • It is custom matched and fit to a patient’s joint size and shape
  • Significantly less cartilage and bone is removed than traditional joint replacements
  • It is placed into the surface rather than on top, leaving the joint less surgically altered
  • Joint motion and the native structures are preserved so no bridges are burned

With the Arthrosurface® Joint Restoration System, the surgeon only resurfaces the damaged area, similar to the way a dentist fills in a cavity. This leaves the rest of the structures in your joint intact so your native anatomy is preserved.

Surgery and Recovery Expectations

Patients report outstanding pain relief, rapid recovery times and significant range of motion improvements in multi-center studies and the procedure may be performed on outpatient basis.

Every surgery has risks and your prospects for a safe and successful surgery must be evaluated with your surgeon. Many patients return to full activity after rehabilitation and go back to doing things that they had given up on in the years before surgery.

orthopaedic surgeonsAfter the surgical repair of a joint, your surgeon will provide you with specific post-operative instructions which you need to follow carefully. Post-operative rehabilitation recommendations will vary depending on the invasiveness of your surgery and your individual recovery patterns.

We wish you good luck with your decision and your treatment.
