Abstract
Background Current scientific evidence reveals that overuse injuries may be more prevalent in youth basketball players than previously reported. Many basketball injuries result from gradual onset overuse mechanisms associated with pain, but not resulting in absence from basketball participation.
Objective To determine the season prevalence and burden of all complaint overuse knee injuries (OKIs) and ankle injuries (OAIs) in youth basketball players.
Design Cohort study.
Setting Youth basketball, Calgary, Canada.
Patients (or Participants) A convenience sample of 83 (47F, 36M; Ages 16–18; N=7) senior team high school basketball players.
Interventions (or Assessment of Risk Factors) The Oslo Sports Trauma Research Centre Overuse Injury Questionnaire was used weekly to register OKIs and OAIs over 16 weeks.
Main Outcome Measurements Self-reported OKIs (e.g., patellar tendinopathy, patellofemoral syndrome) and OAIs (e.g., Achilles tendinopathy) and symptom duration.
Results Female teams participated in 52 basketball sessions (range 42–61, SD 8.6, 42% games) and males in 53 sessions (range 51–54, SD 1.2, 42% games). In the season, 30.4% of females and 27.8% of males reported an OKI and 19.1% of females and 8.3% of males an OAI. The median symptom duration (burden) of OKIs was 7 weeks for females and 4 weeks for males. Median time to onset for new OKI cases was 4 weeks for female players and 7 weeks for male players. The median symptom duration of OAIs was 9 weeks for females and 2 weeks for males. Median time to onset for new OAI cases was 3 weeks for females and 7 weeks for males.
Conclusions The seasonal prevalence and symptom duration of OKIs and OAIs is higher in female youth basketball players compared to males. OKIs represent a greater proportion of lower extremity overuse injury in males compared to OAIs. Females reported new OKIs and OAIs earlier in the season compared to males.
