Joint Reconstruction, Part 3 – Surface Finishing Standards

While choosing the right implant material is of utmost importance, as discussed in our previous Joint Reconstruction Series post, the significance of optimum surface treatment throughout the entire implant manufacturing process cannot be overstated.

This relates not only to the right surface finish – be it a high-gloss polish for low friction, a textured surface for easy osseointegration, or as preparation for subsequent coating, rounded edges, etc. – but also total compliance with the specified tight dimensional tolerances. The success of a joint implant is determined by the perfect match between the various implant components. This depends, to a large extent, on the surface treatment procedure(s).

With extensive experience in the medical industry, Rosler Metal Finishing is an expert in designing systems and solutions for the treatment of joint reconstruction implants utilizing shot blasting and mass finishing technologies.

Our Joint Reconstruction Series continues with an overview of the stringent finishing standards for endoprosthetic implants.

Joint Reconstruction, Part 2 – Material Standards

Joint reconstruction implants allow millions of individuals to regain mobility and reduce pain. Just as surgical skill is required to implant these artificial joints, so is skillful construction and finish of the joint components themselves.

A leader in surface finishing for medical technology, Rosler Metal Finishing has extensive experience in shot blasting and mass finishing a wide range of medical devices from instruments to implants used specifically for joint replacement.

Our Joint Reconstruction Series continues with an overview of the most common materials used for these endoprosthetic implants.

Material Standards

The most common materials used for joint reconstruction implants are currently titanium and titanium alloys and cobalt-chromium alloys. Both materials are very tough, corrosion-resistant, highly biocompatible, and have proven themselves to be absolutely reliable.

Joint Reconstruction, Part 1 – Expertise for Endoprosthetics

With more than $18 billion in annual worldwide sales, implants for joint reconstruction make up nearly 40 percent of all orthopedic product sales. More active lifestyles and increased life expectation continue to contribute to the rapid growth of this market segment.

Thanks to significant advancements on the material side and enhanced surface finishing technologies, artificial hips and knees can last more than 20 years before they must be replaced. Rosler Metal Finishing’s shot blasting and mass finishing capabilities are examples of processes and equipment that have and continue to evolve to accommodate the demand for increased endoprosthetics which are also known as orthopedic joint reconstruction implants.

These techniques play a key role in intermediate processing steps including cleaning, deburring/edge radiusing, surface smoothing, and surface preparation for coatings after casting, forging, machining, CNC grinding as well as placing the final finish on the implants before they are inserted.
