Knee injury and osteoarthritis outcome score of Korean national ice hockey players.
Hyeyoung Kim, Sujin Hwang, Byoung-Hee Lee
PMID 28931992WHAT IT FOUND
Knee pain, symptoms, daily function, sport function and quality of life were mostly related in 18 Korean national ice hockey players.
Daily function and quality of life were the exception.
Key findings
01Pain-related injuries were reported mostly during training, followed by competition, and causes included skate, puck contact, body check, stick contact, goalie task, and weight training.
02KOOS pain was significantly correlated with symptom (0.614), activities of daily living (0.741), sports/recreation (0.831), and quality of life (0.721).
03Activities of daily living was significantly correlated with sports/recreation (0.843), but not significantly correlated with quality of life.

What it does not show
Only 18 female players from one Korean national training center were studied. The results cannot be generalized to all athletes. The study looked only at the knee and did not assess hip, foot, ankle, or neck injuries. It did not test a treatment or follow participants over time, so it cannot show what caused the reported relationships or what intervention would help. The paper reports correlations among KOOS subscales but not individual KOOS scores. The actual level of knee-related dysfunction is unclear.
Declared interests
Financial disclosure statements were obtained, and the authors reported no conflicts of interest.
The easy way to misread this
Do not read the significant correlations as proof that knee pain causes poor daily function or quality of life, or that treating the knee will improve those domains. The study measured participants at one time, included only 18 players, and did not test any treatment or follow scores over time.
