Abstract

Background Osgood-Schlatter is a common growth-related condition in adolescence and can cause persistent symptoms and decrease quality of life. However, little is known about its long-term consequences for knee-related health in adulthood.

Aim To investigate self-reported knee health of adults diagnosed with Osgood-Schlatter during adolescence compared to data from healthy age-matched populations.

Methods We invited all (n=1218) patients aged 18–55y, diagnosed in secondary care with Osgood-Schlatter during 1977–2020, who were invited to complete a web-based survey. Knee-related health was self-reported on the Knee Injury and Osteoarthritis Outcome Score (KOOS) on subscales: Quality-of-Life (QoL), Symptoms, Pain, and Sport/Rec. Responses were grouped according to pre-specified age groups (18–25, 26–35, 36–45, 46–55 years) and compared using a two-tailed students t-test, to age-matched KOOS values derived from a healthy cohort (Williamson AJSM 2015,n=1000).

Results 400 participants completed the survey (mean age 33.8±13y, 65% men). All mean subscale scores were lower for the surveyed group compared to the healthy cohort (p<0.001). Mean differences between the two groups were (female/male): QoL subscale: 36/19 points (18–25y), 25/27 points (26–35y), 26/33 points (36–45y), 25/23 points (46–55y); Symptom subscale: 15/8 points (18–25y), 8/9 points (26–35y), 18/11 points (36–45y), 10/11 points (46–55y); Pain subscale: 19/9 points (18–25y), 11/12 points (26–35y), 13/15 points (36–45y), 16/10 points (46–55y); Sport/Rec subscale: 36/19 points (18–25y), 30/28 points (26–35y), 38/31 points (36–45y), 33/26 points (46–55y).

Conclusion People diagnosed with Osgood-Schlatter in adolescence have significantly decreased self-reported knee health in adulthood when compared to healthy populations. Future studies should address potential long-term consequences of this condition
