Abstract
BACKGROUND: Patient-related outcomes have become the focus of increased attention when assessing knee arthroplasty. METHODS: We retrieved questionnaires from 485 (584 knees) patients at a minimum of 3years after undergoing primary knee arthroplasty. We excluded bilateral knee arthroplasty, leaving 141 UKA and 245 TKA who rated their satisfaction and expectation regarding pain, range of motion (ROM), daily living function (DLF), return to recreational activity (RRA) and ability to kneel (ATK) on a scale of 0 (worst) to 10 (best). We further collected data on pain level and the modified Cincinnati rating scale. Range of motion was documented pre- and postoperatively at a minimum of six months. The cohort was subdivided into three age groups and compared with each other (Group 1: <55, n=113; Group 2: 55-64, n=117; Group 3: 65+, n=155). RESULTS: Average satisfaction with pain, ROM and ATK for patients under 55 was higher for UKA than for TKA. Patients>65 with TKA were on average more satisfied than patients with UKA in these three items. However, patients under 55 with UKA were up to 2.9 times more likely to have their expectations met when compared to patients receiving TKA. Patients with UKA under 55 rated their joint as good/excellent in 96.0% versus patients in the same age group with TKA in 81.0%. CONCLUSIONS: We found that overall, younger patients who were treated with UKA demonstrated higher satisfaction scores in most subsets when compared with the patients of the same age group who received TKA.
