An Overview of Apex K2 Hip Implants
The Apex K2 hip implant is manufactured by medical device maker OMNI Life Science, Inc. When it arrived on the market, it was revolutionary due to its ability to offer 96 different combinations for the device head and neck, so surgeons could create a perfect match for each patient’s unique body type. In 2004, Apex K2 hip implants achieved FDA approval and were most commonly used to:
- Treat osteoarthritis, avascular necrosis and other non-inflammatory degenerative joint diseases.
- Treat rheumatoid arthritis.
- Correct a functional deformity or congenital dislocation.
- Revise procedures where other devices may have failed.
- Treat fractures of the proximal femur.

Despite the device’s promise, complications associated with the Apex K2 hip implant soon arose. Though its patented Dual Press Hip Stem Technology strengthens the connection between the stem and neck and eliminates extra space at the junction of these two components, thus creating less friction and increasing the safety of the implant – it’s also a metal-on-metal device. As such, there’s always a chance that the two pieces rubbing together could release tiny metal particles into the bloodstream and surrounding tissues, causing a form of metal poisoning called metallosis.
In addition to causing pain and swelling, metallosis can also weaken the joint and bone. It eventually leads to the loosening of the implant and device failure, with the patient requiring a complex revision surgery which involves replacing the metal implant with one that uses ceramic or plastic surfaces. Though some patients will enjoy an improvement of their symptoms after their revision, others experience permanent pain and a loss of mobility for the rest of their lives.
Common symptoms of metallosis include:
- Difficulty hearing, and in severe cases, deafness.
- Cardiomyopathy, including heart failure.
- Cognitive impairment.
- Implant loosening and noise coming from the hip.
- Skin rashes.
- Thyroid problems.
- Vision problems, and in severe cases, blindness.
Unfortunately, metallosis isn’t the only complication associated with Apex K2 Hip Implants. The hip stems are more prone to breaking at the neck, which leads to patients requiring emergency surgery. It’s also common for fractures of the femur to occur around the stem.
Is there an Apex K2 hip implant recall?
Despite the fact that Apex K2 hip implants are known to be associated with a number of serious complications, no recalls have yet been issued in the United States. However, approval for the implant was cancelled in Australia in 2012 after it was found that the device had a higher than expected revision rate of 5.5% at one year after implantation and 9.3% at three years.
