One year after total knee arthroplasty, investigators found no difference between patients who received standard patient education and those who used an e-learning tool and standard patient education with regard to the proportion of patients who were not satisfied with their arthroplasty.

Researchers identified patients with osteoarthritis from the London Health Sciences Centre in Canada and randomly assigned 207 patients to receive standard patient education and 209 patients to use an e-learning tool in addition to the standard education. At 6 weeks, 3 months and 1 year after TKA, investigators obtained patient-reported outcome measures. Between-group differences for patient satisfaction and expectations being met were determined with the risk difference 1 year after TKA.
