Knee Injury

@ Lighthouse Physical Therapy Spokane Liberty Lake

The knee is a very stable hinge joint that allows for flexion (bending) and extension (straightening out) of the knee. The knee is composed of the femur (thigh bone) and tibia/fibula (shin bone), which is stabilized by several ligaments: ACL, PCL, LCL, and MCL. Ligament injuries by themselves do not cause swelling. The meniscus (tissue supporting the joint) is composed of tissue that swells when injured. Knee pain is a very common ailment for people of all ages and all activity levels. If you are suffering from knee pain, swelling, bruising, instability, or a lack of motion, come in and be evaluated by one of our practitioners.

Helpful Tips:

When it comes to knee pain, accurately describing where the pain is felt greatly increases the diagnostic ability of your Physician or Physical Therapist. For instance, knee pain felt behind the kneecap (patella) is almost exclusively related to patellofemoral pain syndrome (PFPS). This can be treaded by determining what is causing the poor tracking of the patella, in the femoral groove. If the pain is felt deeper in the knee, your Physical Therapist will perform several tests to determine if the pain is coming from the ACL, PCL, MCL, or LCL. If the pain is coming from the outside of your knee, the pain is commonly generated from a tight ITB. Lastly, if the pain is coming from the back of the knee, the common culprit is a strained gastrocnemius (calf) or distal hamstring. None of this information is absolute and the Physical Therapist will weigh your subjective information and balance it with imaging and other special tests conducted in the clinic.
