Abstract
Total knee arthroplasty (TKA) is a highly successful operation traditionally reserved for older, less active patients, where the aim of the current research is to evaluate the survivorship at long-term, functional outcomes, patient satisfaction, and durability of TKA in active young adults between the ages of 20 and 35 years. Moreover, our study were enrolled 77 active patients (86 knees) with a mean age of 28.6 years (range: 20-35) at the time of surgery were subjected to a cross-sectional study, which all patients were assessed preoperatively and at an average follow-up of 2 years during March 2023 - March 2025 by applying patient-reported outcome measures (PROMs), radiographic evaluation, and implant survivorship calculations.
In addition, significant improvement was shown in all PROMs at 2 years; KSS-Functional increased by +44.3 points, KOOS-Pain by +52.4 points, and UCLA Activity Score by +3.6 points, as well as 66.2% of the patients experienced a moderate level of activity (UCLA 5-7), and 18.2% were active in high-impact activities (UCLA 8-10) during 2 years follow – up, whereby the all-cause reoperation rate was 19.8% (17 knees), and the most common reasons for revision were aseptic loosening (5.8%) and periprosthetic joint infection (4.7%), that a total of 89.6% of the patients were satisfied or very satisfied, and 90.9% would undergo the operation again.
Due to that, our study concludes that TKA provides great pain relief, functional recovery, and excellent satisfaction in active young patients; it has an unusually high rate of reoperation, nearing two times that of their elderly counterparts.
