Australian authorities restricted sales of the Omni Apex K2 hip replacement after it was linked to a 9.3% three-year failure risk. More recently, studies have raised concerns about metal corrosion, chronic pain, and other side effects that require revision surgery.

The Apex K2 is a modular hip replacement made by Massachusetts-based OMNI Life Sciences. It consists of a metal femoral stem and modular (interchangeable) metal components in the femoral neck and head.
What is the problem?
The Apex K2 was approved by the FDA in 2004 with a 510(k) application, which means it did not undergo rigorous clinical trials because it was similar to other hip implants on the market. Unfortunately, “similar” does not always mean safe.
Apex K2 Linked to 9.3% 3-Year Failure Risk
In recent years, questions have been raised about the risks of the Apex K2. In October 2012, the Australian Therapeutic Goods Administration (TGA) pulled approval and warned about a higher-than-expected rate of revision surgery.
Hip implants are supposed to last from 10-20 years or more. Unfortunately, the Apex K2 was linked to a 9.3% failure-rate within three years and a 5.5% failure-rate within one year in an analysis of data from the Australian National Joint Replacement Registry (NJRR).
Study Finds Metal Corrosion Risk from Apex K2 Hip Implant
Modular components help a surgeon custom-fit the Apex K2 implant to each patient, but it also creates a metal-on-metal interface between the femoral stem and neck.
In October 2015, the Journal of Arthroplasty published a study warning about a risk of metal corrosion and fretting from the anti-rotation pin on 10 separate Apex K2 femoral stems.
Complications noted in the study include:
- Fretting and corrosion
- Deep joint infections
- Sensitivity reactions to metal
- Revision surgery
What is ALVAL?
The Apex K2 has been associated with cases of ALVAL, short for “aseptic lymphocyte dominated vasculitis-associated lesions.” This complication can occur when irritating metal particles are released into a patient’s body from a corroding hip replacement.
Symptoms of ALVAL
- Chronic pain
- Soft-tissue growths known as pseudotumors
- Swelling and inflammation
- Bone loss or tissue necrosis
- Metal poisoning (metallosis)
- Limited mobility
