Alternative to Joint Replacement

HemiCAP Wave

The HemiCAP® Patello-Femoral Resurfacing Systems restore the unique articular surface geometry of the Patella and the Femoral Trochlear groove; creating a congruent pathway by using an intraoperative 3 dimensional mapping  system and contoured articular resurfacing implants.

 

Description
The HemiCAP® Patello-Femoral Resurfacing Prosthesis incorporates a distal femoral trochlear surface articular component that mates to a taper post via a taper interlock, and an all polyethylene patella component. The prosthesis is intended to be used in cemented arthroplasty.

 

Indications
The HemiCAP® Patello-Femoral Resurfacing Prosthesis is intended to be used in cemented arthroplasty
in patients with osteoarthritis limited to the distal patello-femoral joint, patients with a history of patellar dislocation or patellar fracture, and those patients with failed previous surgery (arthroscopy, tibial tubercle elevation, lateral release, etc.) where pain, deformity or dysfunction persists.
Patient selection factors to be considered include:
1) Need to obtain pain relief and improve function
2) Patient’s tibio-femoral joint is substantially normal
3) Patient exhibits no significant mechanical axis deformity
4) Patient’s menisci and cruciates are intact with good joint stability, and good range of motion
5) Patient’s overall well-being is good, including the ability and willingness to follow instructions
and comply with activity restrictions

 

Surgical Approaches for Arthrosurface HemiCAP Wave Arthroplasty
The patient is positioned in the supine position, with a tourniquet on the proximal thigh.
The tourniquet is inflated and a longitudinal incision centered over the patella is made, extending from the quadriceps tendon down just medial of the tubercle. The subcutaneous tissue and superficial fascia are reflected over the patella medially by a blunt, sharp dissection. The fascia is divided and retracted, making sure to leave a cuff of tissue on the medial border of the patella for re-suture or advancement. The dissection is deep in between the vastus medialis muscle and the medial border of the quadriceps tendon and the capsule subsequently incised along the medial border of the patella and patellar tendon. As an alternative, a subvastus approach can be utilized. This approach preserves the vascularity of the patella as well as the quadriceps tendon and the VMO attachment. The same straight longitudinal incision is made, at which point the superficial fascia is incised slightly medial to the patella and bluntly dissected off of the vastus medialis muscle fascia, down to the muscle insertion. The inferior edge of the vastus medialis is identified and bluntly dissected off of the periosteum and intramuscular septum for a distance of 8-10 centimeters proximal to the adductor tubercle. The tendinous insertion of the muscle on the medial patellar retinaculum is identified and the vastus medialis muscle is lifted anteriorly. An L-shaped arthrotomy, beginning medially through the vastus insertion on the medial patellar retinaculum, is performed, carrying it along the medial edge of the patella, at which time the patella can be everted laterally.
Upon completion of the procedure, perform a layered closure of biomechanically important according to accepted surgical technique.
