Abstract
Purpose: To determine if patient-reported outcome measures (PROMs) following anterior cruciate ligament reconstruction (ACLR) differ between female patients younger than 25 versus patients 25 years of age and older.
Methods: A retrospective cohort study was conducted using data collected between October 2012 and November 2022. Inclusion criteria encompassed patients undergoing a primary ACLR using a soft tissue graft with a 2-year follow-up. Demographic information and PROMs were collected preoperatively and at 3, 6, 12, and 24 months postoperatively and included visual analog scale for pain, Marx Activity Rating Scale, and the Knee injury and Osteoarthritis Outcome Score (KOOS), including Pain, Symptoms, Activities of Daily Living, Sports and Recreation, and Quality of Life subscales. PROMs were compared between the two age groups using 2 × 5 mixed-model analyses of variance (group × time).
Results: Eighty-one female patients who met inclusion criteria were included in the analysis. At a mean 2-year follow-up, PROMs improved over time regardless of age group (P < .001), and the proportion of patients who achieved minimal clinically important differences in visual analog scale or KOOS scores did not differ between age groups (P values ranging from .28 to .99). KOOS Activities of Daily Living and Marx Activity Rating Scale were worse at every time point for the ≥25-year-old group, but the change in scores did not differ between the 2 age groups. Those aged <25 years recovered more quickly, having better scores at 3, 6, and 12 months, but then tended to plateau between 1 and 2 years. On the contrary, the ≥25-year-old group improved more slowly and more linearly over the 2 years, with outcome scores similar to the <25-year-old group.
Conclusions: At 2 years after ACLR, KOOS Pain, KOOS Symptoms, and KOOS Sports and Recreation scores were similar in female patients regardless of age, but patients ≥25 years old take longer to achieve these outcomes.
Level of evidence: Level III, retrospective comparative study.
期刊介绍：
Nowhere is minimally invasive surgery explained better than in Arthroscopy, the leading peer-reviewed journal in the field. Every issue enables you to put into perspective the usefulness of the various emerging arthroscopic techniques. The advantages and disadvantages of these methods -- along with their applications in various situations -- are discussed in relation to their efficiency, efficacy and cost benefit. As a special incentive, paid subscribers also receive access to the journal expanded website.
