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
