Uni Knee System


Uni Knee System

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.


•Anatomically Contoured Design
•Femoral component incorporates an anterior flange
•Minimal resection technique
•Porous coated femoral component available in five sizes,left and right
•Tibial tray available in four sizes
•Polyethylene tibial inset available in four sizes and three thickness

Resurfacing Hip


Resurfacing Hip System

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.


  • Cobalt Chrome Hemiarthroplasty
  • Design has been successfully implanted since 1951
  • Curved stem for proper implant positioning
  • Partial resection technique removes 1/3 of the femoral head, removing the AVN affected bone

Total Knee System


Total Knee System

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..


• Preservation of all ligaments
• Preservation of the normal polycentric joint motion
• Requires minimal bone resection
• Restores anatomic function

PSL Hip System


PSL Hip System

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.

The PSL Hip System comes in 3 configurations to provide flexibility for the surgeon to accommodate the needs of the patient. The Living Hip or Ultra short hip stem helps address the issue of thigh pain in some patients. The elasticity of bone is greater than that of metal; therefore, if a stem extends into the anterior bow of the femur it can cause irritation and pain. The Living Hip is proximal to the area of the bend, reducing the chances of irritation to the femur.

The PSL Stem is offered in 3 stem lengths and up to 13 different stem diameters to meet patient requirements. All the PSL Stems continue the principals of Wolff’s Law while adding additional length desired for many applications.

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.


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
