Read the following case:
Jason began playing Hockey at about age 10 when his best friend began taking lessons at the local ice rink. Jasons hockey career continued though middle and high school but ended abruptly in college when he began struggling to handle a full load of courses while majoring in electrical engineering. Jasons life continued with graduation, job, wife, and children. It was not until his son reached the age of 10 and showed an interest in hockey that Jason decided to join an adult league at the age of 43.
Jasons team played during late hours since that was the only time available after work at the rink. Jason loved the feeling of skating fast around the rink and realized he still retained some muscle memory of the skill he once had in high school. He also enjoyed taking his son to public skating sessions on the weekends to share his knowledge about the sport.
It was a rainy Saturday afternoon during a public session when Jason took a quick turn on the ice and felt something pop in his left knee. He immediately felt a sharp pain and his knee felt weak. He called his son over and told him they had to leave the session early.
Jason sat on a bench in the lobby for about 15 minutes to see if his knee would feel better.
Maybe I just tweaked it a little he thought to himself.
Maybe it will feel better if I just sit for a little while.
He pulled up his pants leg to examine his knee and observed the swelling and redness.
This doesnt look good, he thought.
Back at home, Jason rested on the sofa with an ice pack on his left knee. He debated what to do next. Should he just try to tough it out or should he go to the emergency room.
He decided to ask his wife.
Molly, could you come over here and take a look at my knee?
Molly entered the room and saw the swollen left knee.
I think you should go to the hospital she said. This looks like more than just a pulled muscle.
The swelling keeps getting worse and I cant put much weight on it exclaimed Jason.
Get in the car, Im taking you, said Molly.
