Hoag Orthopedic Institute Doctors Author Study Highlighting Safe, Efficient Protocol for Same Day Discharge for Partial Knee Replacement

Successful same day discharge among partial knee replacement patients has proven to be safe and efficient while increasing patient satisfaction, according to a recent study that noted developments in surgical protocol. The article appeared in the November issue of The Journal of Arthroplasty, authored by Hoag Orthopedic Institute surgeons and clinicians.

Irvine, CA, November 15, 2013 --( After unicompartmental knee arthroplasty (UKA), also known as partial knee replacement, day of surgery discharges for appropriately selected patients can be both safe, efficient and even increase patient satisfaction according to a recent study published in the November issue of The Journal of Arthroplasty.

Unicompartmental knee arthroplasty procedures involve the removal and replacement of a "compartment" of the knee joint which is damaged, as opposed to total knee arthroplasty which is the replacement of the entire knee joint.

The study, authored by Hoag Orthopedic Institute (HOI) surgeons and clinicians noted that improvements and refinement of the perioperative pathway and techniques over the last decade allowed for successful same day discharge of 160 consecutive patients at HOI.

“We’re pleased to showcase our successes in building a protocol which is best for our patients, and hope that our model will become a gold-standard for care,” said Dr. Robert Gorab, Chief Medical Officer of HOI and a leading author of the study.

The study found that due to improvements in the process before, during and after surgery, patients can actually be discharged sooner and without uncontrolled pain or nausea. Additionally, none of the patients in the study required overnight admission for side effects of the surgery, and results showed high patient satisfaction following discharge.

Study authors included Joseph Gondusky, MD; Leera Choi, BA; Naila Khalaf, MD, PhD; Jay Patel, MD; Steven Barnett, MD; and Robert Gorab, MD.

“These are exciting results considering our aim has always been and always will be to get our patients back to their daily routines as quickly and safely as possible,” said Dr. Steven Barnett, a study co-author and surgeon at HOI.
