Hyperextended Knee | Symptoms, Treatment And Exercises Let’s Know: Hyperextended knees commonly arise after high-impact activities like jumping or stopping short while running.

Athletes, especially those engaging in contact or extreme sports, are most in danger. This injury commonly causes swelling, moderate to severe discomfort, and soft tissue damage in or around the knee.

Hyperextended Knee | Symptoms, Treatment And Exercises Let’s Know

A hyperextended knee is usually easy to see. The knee typically bends backwards out of alignment with the leg.
Symptoms of hyperextended knees include:

  • Knee discomfort mild to severe
  • Swelling
  • Knee instability
  • Knee weakness, as if it’s giving out
  • Bruising

A hyperextended knee generally causes limited mobility. Straightening or bending an injured knee is tough. Reduced mobility can be caused by:

  • Sprains
  • Swelling
  • Knee weakness

Symptoms vary depending on how far back the knee was bent. The gravity of the injury and damage to the surrounding tissues and ligaments determines the amount of discomfort and swelling.


The severity of the injury determines treatment for a hyperextended knee. RICE is frequently used as the first step in treatment.


Following a hyperextended knee injury, it is prudent to discontinue the activity that produced the damage in the first place.

For an athlete, this may imply missing a few games. Rest may entail not walking on the wounded limb or wearing a brace for the average individual.

During a period of rest, a person may also:

  • Get physical therapy to help you regain your range of motion
  • Utilise pain relievers
  • Use anti-inflammatory medicine


This is a popular therapy for injuries like a hyperextended knee since it reduces swelling and alleviates some discomfort.

It should be applied to the hyperextended knee for about 15 minutes at a time, several times each day. To avoid skin harm, always use ice with a barrier, such as a towel.


Compression entails applying pressure to the damaged knee. There are elastic support bands and condense wraps available for this purpose. You may see some knee compression wraps here.

Compression, like ice, can help relieve discomfort and swelling from an injury. It can also offer some support to a weaker knee.


When feasible, the damaged knee should elevate. The knee should hold above the heart, which is frequently achieved by lying down and raising the leg on a pillow or other comfortable platform.

Treatment For Severe Cases

A hyperextended knee requires surgery to repair ligaments or realign the joint in severe cases. The most common problem is ACL tear. However other tendons and structural supports might be affected. The ACL is a knee ligament. Multiple regions of the knee may require surgery.


It depends on the injury. In less severe cases, a person can recover in 2–4 weeks. During recovery, avoid any activity that aggravates the injury. Also, use the RICE approach. If surgery is required, recovery time will extend. Surgical recovery can take 6 months or longer.

Most people will fully heal after a lengthy time. A doctor may likely recommend physical therapy to help with healing. Even after surgery, muscle strength and range of motion must regain.


Following a hyperextended knee injury, a person can perform various activities. The exercises are designing to develop a range of motion and strength. A person should talk to their doctor or physical therapist about workout possibilities.

Some exercises that a person could do include:

  • Swimming
  • Gentle hamstring stretches
  • Stationary bicycle
  • Leg lifts with straight legs
  • Sits the wall
  • Step-up to the side
  • Quad sets – develop the quads (thigh muscles) by contracting, holding, and releasing the muscles; if lying down, place a rolled towel under the knee for support.

A person’s exercises when recuperating from a hyperextended knee should be easy at first and gradually get more difficult as the knee recovers and strengthens.

The Bottom Line

A hyperextended knee injury may heal completely. To have the best chance of complete healing, one must seek medical attention as soon as possible after an injury. Rest is strict for athletes and energetic people, but it is crucial for hyperextended knee healing.

Exercising and stretching can help prevent hyperextended knees. The muscles surrounding the knees must be robust. Trying the forces before and after exercise is also essential.
