Common knee injuries:
1) Fractured Patella (Knee Cap)
2) Pulled or even Torned Ligament(s)
3) Damaged or worn-out Meniscus (shock-absorber)
4) Damaged or worn-out Cartilage
The above 4 can occur all together in one injury and that was what happened to me years back. OUCH!
Once injured, the ligament is weakened, the knee cap unstabilized hence reoccurrence of injuries after recovery isn't uncommon. Damaged cartilage can also lead to Arthritis and/or Rhumatism!!!
Treatments to Injuries:
1) Less Serious Injury (a strain or something) - Reduce activities, leave knee to heal by itself (approx 2 weeks)
2) Moderately Serious Injury (like mine?) - Restrict movement, leave knee to heal by itself (approx 2 months), rehabilitation
3) Serious Injury - Reconstructive surgery
4) Very Serious Injury - Knee Replacement (OMGosh...)
But, Prevention is better than Cure lor !!!
Preventive Measures:
1) Always wear knee guard(s) especially for vigorous workouts!
2) Train in moderation; too much of a specific workout is bad!
3) Wear sports shoes with good cushioning
4) Always be careful of your postures
