A qualitative investigation of the attitudes and beliefs about physical activity and post-traumatic osteoarthritis in young adults 3–10 years after an intra-articular knee injury

Abstract

ObjectiveTo understand the influence of the injury experience on current attitudes and beliefs about physical activity (PA) and the development of post-traumatic osteoarthritis (PTOA) in youth and young adults 3–10 years after a sport-related knee injury. DesignQualitative study. SettingUniversity Sports Medical/Research Center. Participants20 young adults 3–10 years subsequent to intra-articular knee injury. Main outcome measuresSemi-structured interviews were conducted and transcribed verbatim. Analysis used a constant comparative approach with conceptual labels and categories, axial coding, and selective coding to reveal main themes. ResultsThe four main themes were: acceptance; resiliency and determination; knee confidence; and athletic identity. Participants accepted the impact of the injury on their sporting ability and future PTOA to varying degrees. Participants were often highly motivated to recover and met the injury with resilience. Knee confidence was a major concern. Most participants' athletic identity had evolved; impacted both by life and injury experiences. ConclusionsThis study provides insight into the knee injury experience and resultant attitudes and beliefs regarding PA and PTOA in adolescents. Physiotherapists may assist in secondary prevention of PTOA by promoting PA, addressing knee confidence, and educating about long-term joint health.
