Total knee replacement and how physical therapy can help

Posted on: March 20th, 2023 by Our Team

The knee is a critical joint in the body, allowing us to walk, run, and move freely. Unfortunately, it is also one of the most commonly injured joints, leading to pain, discomfort, and reduced mobility. In severe cases, a total knee replacement (TKR) may be necessary to restore function and alleviate pain. However, undergoing surgery is just the first step on the road to recovery. Physical therapy is an essential component in ensuring optimal outcomes for TKR patients.

What is total knee replacement?

Total knee replacement is a surgical procedure that involves removing the damaged parts of the knee and replacing them with an artificial joint. This procedure is typically recommended for individuals who suffer from severe knee pain and disability due to various conditions such as osteoarthritis, rheumatoid arthritis, or injury. The artificial joint is made up of metal, plastic, or ceramic components that mimic the natural movement of the knee joint.

How physical therapy can help

Physical therapy plays a crucial role in the rehabilitation of patients who have undergone total knee replacement surgery. After the operation, the goal of physical therapy is to help patients regain their strength, mobility, and independence. Physical therapists design customized treatment plans based on the patient’s individual needs, which typically includes exercises to improve range of motion, balance, and strength.

Here are some of the ways that physical therapy can be beneficial for patients who have undergone total knee replacement:

  1. Pain management: Patients often experience significant pain following surgery, which may hinder their ability to perform daily activities. Physical therapists can use various techniques to manage pain, such as cold therapy, Electrical stimulation, vasopneumatic compression, manual therapy, and stretches.
  2. Improved range of motion: Physical therapy can help patients regain their range of motion, which is essential for performing activities of daily living. Exercises can be tailored to the patient’s level of ability and gradually increased over time to improve flexibility.
  3. Strengthening: Physical therapy helps to strengthen muscles around the knee joint, improving stability and reducing the risk of falls. Strengthening exercises can also help patients to return to activities they enjoyed before the surgery, such as walking, swimming, or playing sports.
  4. Balance and coordination: After total knee replacement, patients may experience difficulty with balance and coordination. Physical therapy can help to address these issues by incorporating exercises that focus on balance and coordination.
  5. Education and support: Physical therapists provide patients with education and support throughout the rehabilitation process. They can teach patients how to use assistive devices, such as walkers or canes, and provide guidance on how to perform exercises correctly.


Total knee replacement is a common surgical procedure that can significantly improve the quality of life for patients suffering from knee pain and disability. However, the success of the surgery depends on the effectiveness of the rehabilitation process. Physical therapy is an essential component of the rehabilitation process, providing patients with the tools they need to regain their strength, mobility, and independence following surgery. By incorporating physical therapy into the rehabilitation process, patients can achieve optimal outcomes and return to their daily activities with confidence.
