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

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:
o Swelling in the knee occurs within minutes
o Athlete may be in mild to severe pain
o Walking is difficult
o
Treatment:
o See your Athletic Trainer or Orthopedic Doctor
o Long-term treatment may require surgery and
significant physical therapy rehabilitation
o Recovery usually takes average of 6 months
o Full function, mobility, strength and comfort
typically return at about 1 year
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

Treatment:
-See your Athletic Trainer or
Orthopedic Doctor
-Rest
-Wear a range of motion
restricted brace
-Ice
-Elevate
-Surgery may be required
-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.
Rehabiliation
-Program will be created by
Physical Therapist or Athletic
Trainer
-Depending on level of sprain,
recovery may take 2 weeks to
several months
-Meniscus: Functions as a
-
-
cushion between bones
The cartilage of the knee can be
acutely injured or can gradually
tear.
Signs and Symptoms:
-
-
-
Pain with walking up/down
inclines
“Giving away” of the knee
Swelling occurs gradually over
many hours
See Athletic Trainer or
Orthopedic Doctor for full
evaluation

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


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.
