SORI sees, on average, of 400 new patients for total knee replacements (TKR) per year and follows up with almost 700 patients who had a TKR with Drs Parker, Coolican or Fritsch.

SORI has focused on a number of different ways to improve TKR procedures in order to increase accuracy and reduce post-operative pain.



Pain: Researchers at SORI have analysed the correlation between intra-operative anaesthesia choice and short-term post-operative pain, as measured by patient self-reporting.

Rehabilitation: Researchers at SORI are currently tracking the progress of nearly 200 patients followed out to one year post-TKR surgery. This randomised control trial examines whether playing active games on a Nintendo Wii can positively impact rehabilitation post knee replacement compared to traditional home exercises.

Tibial baseplate fixation: During a TKR there are several different methods to fix the tibial baseplate the tibia (lower leg).We are currently tracking a large group of patients analysing three different methods: cemented to the tibia, screwed, or uncemented. This randomised control trial will be ongoing for several years to come, examining patient outcomes and implant survival, as SORI will follow-up with patients up to 10 years post-surgery.
