Case Study:

Primary Knee replacement with custom instrumentation in a 63 year old male

A 63 year-old male who was referred to our clinic with end-stage left knee arthritis for consideration for a Total Knee Replacement. We assessed him at our clinic, including his medical history and his suitability for surgical management of his arthritis.

We ultimately deemed him to be a candidate for knee arthroplasty surgery, and were also able to offer him Patient-specific knee Instrumentation surgery. This involved sending Mr. TF for a knee MRI that he otherwise would not have received if he were receiving standard knee instrumentation surgery. This scan was then sent to the implant company who then used it to create instruments for use during the procedure that were specific to Mr. TF’s knee anatomy.

These custom instruments allowed us to make specific bone cuts that matched the inner surface of the knee prosthesis. The advantage of these cuts is that they would result in minimal amounts of bone being removed to complete the procedure. The steps in the procedure itself do not change, and the components implanted match the outer surface geometry of standard implants in order to replicate optimized biomechanics.

Mr. TF recovered very well from his procedure, and was discharged from hospital the day after his surgery. He is doing well 1 year after his surgery, and is pleased to have had the opportunity to have benefited from instrumentation specific to his anatomy, and would recommend it to anyone who has a similar opportunity.
