Hip HemiCAP® Implant
The Hip HemiCAP® provides a new, smooth surface within the Hip Joint. By removing the damaged cartilage and dead bone in the joint, the healthy bone underneath will be exposed and used to implant the HemiCAP® into. The HemiCAP® is designed to alleviate pain, remove the dead bone and reduce the opportunity for collapse. Because most of these patients are between the ages of 30 & 50 years old, it also postpones the need for a total hip replacement for many years.
Resurfacing 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 where the cartilage has worn away — imagine a filling for a tooth cavity. It is a contoured surface that goes into the area of damaged cartilage, not on top of the bone. It’s 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 in over 10 years.
Could I be A Candidate?
Typically, an Arthrosurface Hip HemiCAP® procedure is for a patient who has been told by their doctor or orthopaedic surgeon that they have:
- Cartilage Damage on the Femoral Head
- Avascular Necrosis (AVN) / Osteonecrosis
- Pipkin Fractures
After trying non-operative treatments, such as pain and anti-inflammatory medications, cortisone injections and physiotherapy, the pain remains problematic and debilitating, affecting your daily activities and your sleep, as well as your ability to stay active. Most likely, you have been told that your next option is a total hip replacement, and while this may be a viable option later in life, your younger age puts you at a higher risk for an early revision. Each successive total joint replacement (revisions) compromises the amount of bone you retain in your joint. Revision implants are also known to have a shorter lifespan than the original total hip replacement.

Surgery and Recovery Expectations
In multi-center studies, patients reported outstanding pain relief, rapid recovery times and significant range of motion improvements. 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. A successful joint restoration procedure may significantly improve your quality of life by reducing pain and restoring function. Many patients return to full activity after rehabilitation and go back to doing things that they had previously given up due to a painful joint.
After 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. The immediate focus in all surgeries will be on swelling and pain management. In some cases you may wear a brace for a few weeks and will be prescribed exercises and activities to begin strengthening your muscles.
