The Knee Joint Bones: Menisci Ligaments: Femur Tibia Fibula Patella Medial Meniscus Lateral Meniscus Ligaments: MCL- Medial Collateral Ligament LCL- Lateral Collateral Ligament ACL- Anterior Cruciate Ligament PCL- Posterior Cruciate Ligament ACL PCL Medial Meniscus LCL Lateral Meniscus MCL

Knee Sprains Sprain-Ligament stretching or tearing Grade-one sprains stretch the ligament but don't tear the fibers Grade-two sprains partially tear the fibers, but the ligament remains intact Grade-three sprains are tears that completely disrupt the ligament

The Anterior Cruciate Ligament and the Posterior Cruciate Ligament ACL- located internally in the front of the knee , prevents the knee from sliding forward PCL- located behind the knee and forms an "X" on the inside of the knee and prevent the knee from sliding backward Signs and Symptoms of injury: Swelling in the knee occurs within minutes Athlete may be in mild to severe pain Walking is difficult Treatment: See your Athletic Trainer or Orthopedic Doctor Long-term treatment may require surgery and significant physical therapy rehabilitation Recovery usually takes average of 6 months Full function, mobility, strength and comfort typically return at about 1 year

The Medial Cruciate Ligament and the Lateral Cruciate Ligament MCL- ligament on the inside of the knee, prevents knee from sliding side to side LCL- ligament located on the outside of the knee, prevents knee from sliding side to side

Possible Injuries: Torn LCL Treatment: -See your Athletic Trainer or Orthopedic Doctor -Rest -Wear a range of motion restricted brace Ice Elevate Surgery may be required Rehabiliation -Program will be created by Physical Therapist or Athletic Trainer -Depending on level of sprain, recovery may take 2 weeks to several months -A LCL tears when stress is placed on the inside of the knee Ex. Kicked from medial (inside) of knee -The picture above shows a hit to the inside of the knee.

Patellar (Knee Cap) Injuries The kneecap sits within the tendon of the quadriceps muscle, in front of the femur, just above the knee joint. It is held in place by the quadriceps muscles - The patella typically subluxates/dislocates laterally (toward the outside of the knee). Dislocations are returned to the normal position by straightening out the knee See your Athletic Trainer or Orthopedic Doctor for full evaluation Rehabilitation will be needed

Bursae Bursa- fluid-filled sac that reduces friction between muscles, tendons and bones Inflammation of the bursas (bursitis) can occur because of direct blows, chronic use and/or abuse. Rehab -See your Athletic Trainer or Orthopedic Doctor -Avoiding aggravating movements such as kneeling -Wear knee pads -If the swelling persists, a medical professional may drain the fluid within or around the bursa. -In cases where the bursa has become infected, antibiotics may be prescribed -In more serious cases the bursa may be completely removed by surgical procedures.
