The Femoral component of the unicompartmental knee offers less soft tissue and bony destruction which means quicker rehabilitation with a high rate of long term success. The implant allows for minimum bone resection and offers multiple thickness polyethylene inserts to accommodate varying tibial plateau deficiencies. The anterior flange allows for more consistent tracking of the patella.

The BioPro® Total Articular Replacement Arthroplasty is a conservative, bone preserving prosthesis used as a hemi-arthorplasty. The implant requires the resection of one third of the femoral head. Preserving the maximum amount of bone possible.

It is an excellent option for avascular necrosis or arthritis of the hip where the acetabular cartilage is still in good condition. The implant provides patients with an excellent option over conventional hip replacement. In the event that total replacement is necessary in the future, minimum resection required for the BioPro® implant allows for sufficient bone stock for conversion to a primary total hip.

As a resident, Dr. Charles Townley first sketched his ideas of a total knee replacement in the early 1940’s. The BioPro® TKO (Total Knee Original) knee replacement implant is the third generation of Dr. Townley’s original total knee replacement. It has been designed to provide anatomical articulating surfaces while preserving all of the stabilizing ligaments including the ACL (anterior cruciate ligament) and PCL (posterior cruciate ligament). Recent studies have shown that knee replacements which preserve the ACL and PCL have a more “natural” feel than those that sacrifice the ligaments..

Few hip designs in today's marketplace take advantage of the known forces present in the femur. Long term stability of a total hip prosthesis requires an implant design and fixation technique that simulates the normal transmission of weight bearing forces through the prosthesis to the supporting bone structure.

Wolff's Law

Dr. Charles Townley based his PSL (Physiological Stress Loaded) design on Wolff’s law which states that “bone grows and remodels in response to the forces that are placed upon it”. The PSL design has clinically demonstrated its ability to resist bone loss due to proximal stress shielding by positioning the collar perpendicular to the resultant forces, Which maximizes the recreation of natural forces.

FEMORAL HEAD OPTIONS

The PSL Hip System comes with multiple femoral head options including:
•Ceramic Femoral Heads in 28mm and 32mm diameters
•Cobalt Chrome Femoral Heads in 22mm, 28mm, 32mm, and 36mm diameters
•Uni Polar Heads from 38mm to 55mm diameters
•Bipolar Head Options from 38mm to 60mm diameters
