Revision Hip
Replacement
As part of my clinical practice, I perform revision total hip and total knee arthroplasty procedures. Revision hip and knee arthroplasty procedures are performed for a variety of indications. Typically, they are performed when previously placed implants fail. This can be secondary to mechanical failure, implant loosening, dislocations, or infection. These surgeries are more technically complex than their primary counterparts. They involve removing failed implants and replacing them with new and more extensively fixed revision style implants.
The recovery following revision surgery is more involved, hospital stays are longer, and patients may be placed on precautions including periods of limited weight bearing and movement as they heal from surgery. Typically the period of recovery ranges between from three to six months following these more involved surgical procedures.

Implants and Materials
Revision total hip arthroplasty represents a spectrum of potential surgeries. In some instances a modular revision can be performed in which only the femoral head and liner are exchanged. Typically, however, the revision involves removal of either the femoral, acetabular, or both components. In these instances, the revision components require augmented fixation in the now disrupted bone stock.
As such, revision acetabular components often utilize multiple screws to improve component ingrowth and prevent component migration. Additionally, revision femoral stems are often longer than primary stems (see x-rays above) to allow for a greater ingrowth surface area and improved contact with host bone.
Following revision surgery, the risk of dislocation is increased when compared to primary arthroplasty. As such, dual-mobility implants are commonly used to mitigate this risk, improve joint stability, and maximize functional outcomes.
I can’t thank Dr. Adam Sassoon and his team for their outstanding care and helping me get through a very unexpected and challenging situation. My misfortune turned into good fortune when I landed in the ER and in their great care. Dr. Sassoon and Jennifer Lew PA are a dynamic duo… they both are highly skilled professionals who undoubtedly work together to deliver exceptional outcomes with complex cases like mine. I appreciated their open communication, kindness, and compassionate care. Thank you for getting me back to doing the things I love with a new pep in my step. You are Awesome and I am truly Grateful! 💕

REVISION HIP SURGERY PATIENT
There was a debate if I should transfer to a hospital closer to home or to stay with you. The word had arrived that the very talented Dr. Sassoon would lead and could basically fix anything that was broken. The surgery on the Monday was a success… 6 hours later and a few transfusions… Thankfully, I never made that move. The professionalism, talent, quality of treatment at UCLA was best in class! You both should be proud of your affiliation and also what your own personal name and performances do for the brand!
You & your team eased my pain and rebuilt my spirit as I regained my wits post-surgery. Every moment I was in your house; your talented colleagues provided me with warmth, care and encouragement. I honestly know that if it was not for all of you I have no idea where I would be today.”
