The aim of the following study was to survey the activity level and the health-related quality of life of patients following lateral UKA. Methods: Forty-five patients were surveyed to determine their sporting and recreational activities at a mean follow-up of 3years (range 2.0-4.3years) after lateral UKA. We also assessed health-related quality of life of our patients at the time of the survey by use of the SF-36 Health Survey. Results: Before the onset of the first restricting symptoms, 42 of 45 (93%) patients were active in at least one sport compared to 43 of 45 (96%) patients after surgery resulting in a return to activity rate of 98%. Within 3months, 56% returned to their activities after surgery and 78% within 6months. The mean postoperative UCLA score was 6.7 (±1.5). Two-thirds of the patients reached a high activity level (UCLA ≥7).Most common activities after surgery were biking, hiking and long walks. While high-impact activities showed a significant decrease, low-impact activities showed a significant increase. The main reason for a decrease in patients' level of activity was precaution. There are no statistically significant differences in the postoperative scores of our patients and those of a matched healthy reference population in the SF-36 scores. Conclusion: The results of the present study demonstrate that a vast majority (98%) of our patients independent to age or gender returned to sports and recreational activity after lateral UKA. Two-thirds of the patients reached a high activity level. Activities patients were most participating in were low- or mid-impact, whereas high-impact activities were mostly given up. Further follow-up is necessary to assess the effect of activity on implant fixation and wear. Level of evidence: Retrospective case series, Level IV.
