The Talus (Ankle) HemiCAP® is approved for patients via CE Mark in countries outside of the United States for ankle pain relief. Most talus defects are located on the inside part of your foot and are usually deep and cup-shaped. Ankle sprains are the primary cause of traumatic defects. When the ankle twists during an ankle sprain, the cartilage lining of the talus can become damaged. This may lead to a bruise, subsequent softening of the cartilage, or a crack in the cartilage which can develop into a flap of unattached cartilage.
The HemiCAP® Talus implant is a joint restoration system designed to match the shape and contour of the individual patient’s cartilage surface. It is a contoured cap that goes over the area of damaged cartilage and is designed to protect the remaining (healthy) cartilage in the joint. The HemiCAP® is two components that consist of a cap and screw that mate together via taper lock. The idea behind the system is to prevent further damage to the joint while maintaining the patient’s native anatomy and motion.
The HemiCAP® system matches not only the diameter of the damaged area but also the precise radius of both curvatures on the patient’s joint surface. Once the mapping points are defined, the appropriate implant is chosen and then implanted into the patient. Different diameters & curvatures are available to provide a proper fit for each individual patient.
The Talus HemiCAP® is typically for someone told by their doctor or orthopaedic surgeon that a previous procedure has failed. Most likely, you have been told that your next option is an ankle fusion or Total Ankle Replacement, which is considered major surgery. An ankle fusion will seriously limit the motion of your joint while a Total Ankle Replacement removes significant amounts of bone with both requiring extended rehab and physical therapy. Though the Talus HemiCAP® also requires surgery, it is much less invasive by only restoring the damaged area of the joint. Since you don’t want anything that is going to restrict your active lifestyle a less aggressive option may be a good option.
You may be a Candidate if you have:
- Painful and debilitating Ankle Arthritis
- Ankle pain that has not improved with non-operative and operative treatments
*Seek professional medical advice for specific personal care.
Your surgeon will only resurface the damaged area of the joint, similar to the way a dentist fills in a cavity, leaving the rest of the structures in your joint intact. This way, your native anatomy is preserved, the exposed and painful bone is covered, while all th
e structures in your joint that help you move and function properly are left in place allowing you to return to your normal active lifestyle.
- Little to no activity restrictions making the Arthrosurface® implants an active alternative to ankle replacement
- 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
Every surgery has risks and your prospects for a safe and successful surgery must be evaluated with your surgeon. If you are affected by osteonecrosis or cartilage damage caused by a previous injury, 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 given up on in the years before surgery.
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 how invasive your surgery is 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 strengthen your muscles.
The postoperative management consists of a plaster cast for 1 week, after which full range of motion is ensured. A functional non–weight-bearing brace (walker) or a detachable plaster cast can be applied for another 5 weeks. During this period, non–weight-bearing sagittal range-of-motion exercises are allowed for 15 minutes twice a day. After these 6 weeks, radiographs of the operated ankle are obtained to confirm that the ankle bone has healed. Subsequently, physical therapy is subscribed to assist in functional recovery and extend to full weight bearing in approximately 1 month.
Here are a few helpful suggestions as you recover and rehabilitate from your surgery:
- Follow the recommendations of your surgeon and physical therapist.
- Keep a log to track your progress as you recover and increase activity.
- Ask for assistance from family and friends to help with chores and errands during your recovery.
- Wear loose, comfortable clothing during your recovery period.
- Eliminate possible tripping hazards in your home – wires, cables, rugs, etc.
- Return to any moderate or demanding activities should be guided by your tolerance for weight bearing.
If you are a patient with disabling ankle (talus) pain who has been advised by a surgeon that you may need an ankle replacement or fusion, you may be a candidate for HemiCAP® Resurfacing.
