What Is ASR?

ASR stands for “articular surface replacement” and has become a popular option for those receiving hip implants. Articular surface replacements are commonly used for patients who may need another hip replacement in the future or for those patients who want or require a range of movement post surgery because of the amount of bone that the surgery typically conserves. As opposed to total hip replacements, the femoral head and bone from the femur are not removed.

In an ASR surgery, only the injured parts of the hip joint are replaced, which is what allows the majority of the bone to be preserved. Typically this type of surgery involves reshaping the femoral head with an artificial shell.

ASR surgeries used to be performed with metal-to-polyethylene implants; however, the size of the polyethylene caused there to be greater wear on the prosthesis and, thus, greater problems. Now, articular surface replacements are done with metal-to-metal implants that usually provide a greater resistance to wear, but may also have other undesirable side effects.

While many hip implants do provide immeasurable relief to patients who receive them, some patients are not so lucky. If you have suffered from complications or further health issues due to a defective DePuy hip implant, you may consider joining a DePuy class action lawsuit. However, the DePuy lawyers at Williams Kherkher firmly believe that pursuing compensation on your own, or through a mass tort lawsuit, is the best way to effectively pursue the compensation you need at this time.
