Partial knee replacement, also called unicompartmental knee arthroplasty (UKA), may be an option for you if you have moderate joint disease or injury in which only part of the damaged knee, either the medial (inside), lateral (outside), or patellar femoral compartment, will need to be replaced. Partial knee replacement is designed to cause less trauma by removing less bone, using smaller implants, and maintaining most of the natural bone and anatomy. Your incision will be small, disrupting less of the soft tissue surrounding the joint. The procedure may involve arthroscopic surgery, in which the inside of your knee is viewed through the use of a very small camera.

Hoag Orthopedic Institute is where you will find expertise in partial knee replacement surgery. The orthopedic surgeons who have aligned their practices with Hoag have been trained on the newest surgical techniques including navigation and patient specific instrumentation. Various techniques and implants exist, and your surgeon will determine the implant type and manufacturer, as well as what surgical technique will be used.

Your partial knee replacement may be scheduled as outpatient, short stay surgery, or as a short inpatient stay where you will benefit from Hoag’s state-of-the-art operating rooms and their outstanding one-to-one or one-to-two ratio of nurse to patient. The focus of the entire Hoag Orthopedic team will be on safety, pain management and the optimal outcome. A more minimal surgery means less pain, and quicker healing as compared to conventional total knee replacement surgery.

As with any surgery, your post-operative rehabilitation is a critical component of your recovery. At Hoag, your physical therapist will be an orthopedic dedicated specialist working closely with your physician in order to help you regain full, optimal use of your knee. To derive maximum benefit from your surgery, you will be given a personalized rehabilitation plan. You can expect to walk without the assistance of a walker or cane fairly quickly and return to full activity at around a month.
