Stryker Rejuvenate, ABG II, and V40 Hip Replacement Devices
Stryker Rejuvenate and ABG II
In 2008, Stryker released the Stryker Rejuvenate and ABG II hip devices onto the U.S. Market. These products make up the femoral components of a total hip replacement product, specifically, the femoral stem pieces. The Rejuvenate and ABG II products are considered modular, rather than monolithic. This means that instead of there being one rod to insert into the hip femur, there are two pieces, the neck and stem, that fit together.
Stryker LFIT COCR V40 Head
The Stryker LFIT COCR V40 femoral head product has been on the U.S. market since the early 2000s. The metal V40 head is placed onto a femoral neck in a total hip replacement procedure. When a metal femoral neck is used, which is primarily always the case, pairing a metal head with a metal neck creates a metal-on-metal interface. The Stryker V40 head is often paired with the Stryker Accolade neck, which is made of metal.
Case Quick Facts
Stryker Rejuvenate and ABGII
Stryker touted its Rejuvenate and ABG II modular products as being beneficial over monolithic femoral components because they allow for specific adjustment for the size and offsets of each patient’s body makeup. However, the neck-stem pieces, unlike the monolithic pieces, have the capacity for metal-on-metal wear at the neck-stem interface.
Specifically, it was found that micro-movement would occur between the neck and stem pieces, causing fretting and corrosion of the neck-stem tapers. This would cause dangerous metal ion release into the body, metallosis, pseudotumor, and the need for very invasive revision surgeries.
The Stryker Rejuvenate/ABG II products are made of a material Stryker designed called TMZF. This is a titanium metal combination that allows for flexibility in the material. While Stryker touted this flexible material as beneficial for patient movement, the flexibility also lent to increased micro-movement resulting in fretting and corrosion.
In July 2012, Stryker recalled its Rejuvenate and ABG II modular necks from the U.S. market.
Stryker LFIT V40 Femoral Heads
In August 2016, Stryker initiated a voluntary recall of several of its LFIT COCR V40 femoral heads, claiming reports of metallosis and corrosion at the neck-head interface. The V40 head is often paired with the Stryker Accolade neck. Some versions of the Accolade neck are made of the same material, TMZF, of which the Stryker Rejuvenate femoral components were comprised. Patients are reporting similar complaints as to those involved in the Rejuvenate cases, including, metallosis, pseudotumors, pain, and need for revision surgery. Additionally, some of these V40 devices have been found to disassociate from the femoral neck causing severe damage.
In May 2018, Stryker warned that certain LFIT V40 femoral heads, manufactured between 2001 and May 2011, were linked to a high number of complaints involving femoral head/hip stem dissociation. This can lead to serious complications, including loss of mobility, adverse local tissue reaction, dislocation, pain due to implant loosening, leg length discrepancy, and need for revision surgery. Stryker did not have healthcare providers return the affected LFIT V40 femoral heads and has advised surgeons to continue normal follow-up with patients that receive the implant.
The main concern with the Stryker ABG II, Rejuvenate, and B40 hips is the fretting and corrosion of the stem and neck joint, which can cause elevated levels of chromium and cobalt in the bloodstream (metallosis). This can lead to the following complications:
- Pain/limited mobility
- Tissue inflammation/swelling
- Formation of tumors or pseudo-tumors
- Bone loss or dissolution
- Tissue death (necrosis)
- Adverse Local Tissue Reaction
- Elevated metal levels or metallosis
- Need for revision surgery
In these cases, Stryker is the defendant, as they developed and created the Rejuvenate, ABG II and V40 hip replacement devices.
A multidistrict litigation was created in the District of Minnesota as well as a consolidated action in New Jersey State Court to address the recalled Stryker Rejuvenate and ABG II hip products. In 2014, the first Stryker rejuvenate/ABG II global settlement was announced. In 2016, a second global settlement was announced to include individuals who experienced device failure after the deadlines of the first settlement. There are currently still many people being injured by this product. The litigation against Stryker is ongoing.
Shortly after Stryker recalled some of its V40 heads, a multidistrict litigation was created in the District of Massachusetts to address the failure of the Stryker V40 hip product. This litigation is currently ongoing and GoldenbergLaw is accepting cases.Do I Qualify?

A study on the prevalence of pseudotumors in metal-on-metal hip recipients published in The Journal of Arthroplasty showed that, “68.6% [of patients evaluated] developed pseudotumor with 60.9% of the asymptomatic group developing pseudotumor.” The study also showed that elevated cobalt levels in the bloodstream were associated with larger pseudotumors.
Infection is a possible negative side-effect of getting a hip implant. Unfortunately, about 1/100 hip-implant patients experience a hip infection after their implant surgery.
