Knee > Knee Hyperextension
The knee moves through a wide range of motion with a bony block when the knee is fully extended. Knee hyperextension occurs when the knee gets forcefully extended past its normal range of motion causing damage to the connective tissue in the joint.
Mechanism of Injury: Knee hyperextension can be a result of a traumatic event such as a hit to the front of the knee or when another person falls on top of an outstretched knee.
Contributing Factors: Muscle weakness, generalized joint hypermobility.
Signs/Symptoms: Pain with movement. Feeling of instability. Inability to weight bear. Loss of range of motion. Swelling/discoloration.
At Home Tests: Bounce Home Test (see video)
At Home Treatment: Rest. Ice on/off for 20 mins. Elevation.
When to Seek Help: Contact your physical therapist if the pain does not subside or gets worse after 7 days. Contact your physical therapist for post-operative rehabilitation.
Treatment at Inspired Athletx: Your physical therapist will first assess for any damage to your ligaments, meniscus, and other structures of your knee to determine if you need further medical assessment (i.e. medical imaging, ortho consult) for a tear. Initial treatment will focus on reducing spasm and improving mobility in your knee. As pain diminishes and mobility/function return, your therapist will address contributing factors, including hip/quad weakness, stiffness in the adjacent joints (ankle/hip), and inefficient movement patterns.
