Robotic/Computer Assisted Hip Replacement

Technology has improved surgical accuracy for those suffering with hip problems. MAKOplasty is a robotic-assisted procedure for partial-knee and total-hip replacements. The robot aids in providing precision and helps in multiple ways: first it allows us to remove the diseased bone and maintain healthy bone. Next it allows perfect positioning of all components of your total hip, specific to your anatomy. This optimizes longevity of the hip and restores the leg length and hip alignment perfectly. This also helps with rapid recovery.

In the office we will begin by ordering a special CAT scan. This CAT scan of the patient’s hip and pelvis will be used to create a 3-D image and model. This gives the surgeon a blueprint to work with and prepare a customized plan for each patient. The computer software then uses sensors placed on the patient during the surgery to match the body with the computer. This is much like satellite technology, matching the earth to your location in your car. A virtual image is then used during the procedure in order to perform the surgery and reflect the preoperative plan.

When the procedure begins, the computer uses its models to assist the surgeon in removing the worn out and diseased bone. After the hip and pelvis are prepared specific for each patient, new total hip components are placed using the robotic arm to position them perfectly.

Following the procedure, patients are usually admitted to the hospital for 1-2 days and should expect normal postoperative pain. However, the pain from the previous arthritis should be gone. Patients are usually able to walk with assistance several hours after the surgery and may only need a cane or crutches for a couple of weeks. Within 4-6 weeks a patient may return to normal function.
