Knee pain and knee injuries are public complaints to both general practitioners and orthopaedic surgeons. Knee injuries, happening many times in males (<30 years of age), are a prime origin of pain and disability, and a widespread public fitness concern about healthcare costs and work disability.

Musculoskeletal disorders and injuries are common causes of morbidity and loss of active, physically demanding training days in military populations. The observed study incidence, diagnosis, and risk factors for knee disorders and injuries in male Finnish military conscripts. The study population comprised five cohorts of 1000 men accomplished their military service, categorised following birth year (1969, 1974, 1979, 1984, and 1989). Estimate time for each conscript was the separate conscript’s full, completed military service period. Data for each man were Incidence and risk factors for exercise-related knee disorders in young adult men. Knee pain and knee injuries are intimate complaints to both general practitioners and orthopaedic surgeons. Knee injuries happened utmost often in young men (<30 years of age), are a leading cause of pain and disability, and widespread public health consternation about healthcare costs and work disability. Musculoskeletal disorders and injuries are general causes of morbidity and loss of active, physically demanding training days in military populations. Evaluate the incidence, diagnosis, and risk factors of knee disorders and injuries in male Finnish military conscripts. The study population comprised five cohorts of 1000 men performing their military service, categorised following birth year (1969, 1974, 1979, 1984, and 1989). Follow-up time for each conscript was the separate conscript’s full, completed military service period. Data for each man were obtained from a standard pre-information questionnaire utilised by defence force healthcare officials and from all original medical survey of the garrison healthcare centres. Studied difference for risk factor analysis involved the conscripts’ service data, i.e., age, height, weight, underweight, overweight, body mass index (BMI), service class (A, B), length of military service,  obesity, smoking habit, education, diseases, injuries, and subjective manifestations.

Of the 4029 conscripts, 853 visited the healthcare provider for knee manifestations among their military service, and 103 of these had agonised a knee injury. Independent risk factors for the prevalence of knee manifestations were: older age; service class A; overweight; smoking habit; comprehensive school edification only; and self-reported previous manifestations of the musculoskeletal, respiratory, and gastrointestinal system. The most of visits to garrison healthcare services due to knee manifestations showed during the first few months of military service. Knee symptoms were negatively associated with self-reported mental and behavioural disorders.

To highlight the prevalence of knee disorders and injuries in young men among physically demanding military schooling. One-fifth of the male conscripts inspect defence force healthcare professionals due to knee manifestations during their service period. Independent risk aspect for the incidence of knee manifestations during military service was the age at military service; military service class A; smoking habit; overweight; comprehensive school education only; and self-reported previous signs of the musculoskeletal system, gastrointestinal system or respiratory system. These risk factors should be considered while planning and implementing procedures to reduce knee disorders and injuries during compulsory military service.
