Small incision, less recovery time.

The Arthrosurface HemiCAP® system restores the cartilage surface geometry of the Femoral Condyle and preserves functional structures using an innovative 3-dimensional mapping system and a contoured articular resurfacing implant. The instruments and techniques are identical for each joint so the procedure can be performed by the same surgeon on multiple joints with a minimal learning curve.

*This system is not available in the US, but is available in most international markets.

Product Features

toe replacement

  • Restoration of a smooth, continuous load-bearing surface to slow and/or stop further mechanical wear and deterioration of the surrounding joint surfaces
  • A simple, reproducible and less invasive outpatient/ambulatory surgical procedure
  • Designed for patients with localized damage who want to resume an active lifestyle
  • Inlay components preserve the joint, maintaining future options: “no bridges burned”
  • One tray with a  simple, reproducible technique and instrumentation
  • Little to no activity restrictions making the Arthrosurface® implants an active alternative to knee replacement

Surgical Technique

toe surgeryThe Femoral Condyle HemiCAP® implant system is comprised of two parts, an articular cap and a fixation component. The instruments are organized in the order of surgery, proceeding from left to right and top to bottom. The procedure begins with a guide to identify the femoral lesion. Then place the guide wire perpendicular to the head and use a step drill to prepare the screw hole. The fixation component is advanced so the line on the screwdriver is slightly below the existing cartilage surface so the HemiCAP® will be seated approximately .5-1mm below the surrounding surface. The uniquely designed instruments are used to map the contours of the patient’s native surface curvatures using the fixation component as a central axis.  A reamer then removes the damaged cartilage to create a socket for the implant. A trial is then placed to assess the proper implant fit. Once the surface preparation is complete, the HemiCAP® implant is positioned and seated with several taps of the mallet.

Advantages for the Patient

toe replacementThe Femoral Condyle HemiCAP® technology was designed so patients can continue working and retain an active lifestyle without compromising future treatments.

  • Bridges the gap between biological therapies and total knee replacements
  • Clinical studies demonstrate positive clinical outcomes at 5-7 years post op
  • Patients report pain relief, rapid recovery and full range of motion
  • The procedure may be performed on outpatient basis
  • Allows for preservation of bone and soft tissues
  • Maintains existing joint biomechanics, thereby allowing normal motion
  • Patients are experiencing a rapid return to activity for both work and exercise
  • Little to no activity restrictions making the Arthrosurface® implants an active alternative to knee replacement

Advantages for the Surgeon

knee pain

  • The minimally invasive outpatient procedure typically takes less than an hour
  • Soft-tissue envelope and native joint biomechanics are maintained
  • Skeletal anatomy and bone stock are preserved allowing future joint replacement
  • Inlay components preserve the joint, maintaining future options: “no bridges burned”
  • Intuitive, universal, reproducible procedures across multiple joints
  • The two components are connected together via morse taper, with zero reported loosening

  • Quick Facts

    • The most common cause of knee pain is osteoarthritis (OA), a degenerative joint disease that causes the cartilage in your joints to break down. When that layer of cartilage — which is meant to “cushion” the joints and protect the surface of the bones — is damaged or worn away, your bones grind against one another, and that grinding hurts. You can feel it climbing stairs, working in the garden, or just bending your knees to sit. It may even keep you up at night.
    • OA can damage the entire knee or be limited to just one side of the knee. If you experience pain only on one side, or compartment, of your knee, your doctor may diagnose you with unicompartmental OA.
    • If you experience knee pain under the knee cap, your doctor may diagnose you with patello-femoral OA. This is not uncommon, as studies have shown that about one out of every 10 patients over the age of 40 have patello-femoral disease.
    • The factors leading to the development and progression of OA include aging, obesity, joint injuries, and a family history of arthritis (genetics). Although there is no cure, early diagnosis and treatment are crucial in slowing or preventing more damage to your joints.
    • The Femoral Condyle HemiCAP® is a great option for local defects.
    • The Femoral Condyle HemiCAP® is only available in International Markets. Currently not available in the US.
    • It does not remove your ACL, PCL or MCL.
