Physiotherapy After Knee Replacement

When a person suffers from severe arthritis, injury, or other degenerative conditions resulting in chronic knee pain and limited mobility, doctors often recommend knee replacement surgery. Known scientifically as knee arthroplasty, this operation involves replacing the worn-out or damaged parts of the knee joint with artificial components called prostheses. During the operation, the surgeon removes the damaged bone and cartilage from the knee and replaces it with metal and plastic implants. The primary aim of knee replacement surgery is pain relief, function restoration, and an improved quality of life for the patient.

Importance of Post-Surgical Rehabilitation

Rehabilitation after undergoing knee replacement surgery is not just important, it is crucial. To achieve the best possible outcome, patients need to engage in a comprehensive rehabilitation programme. Physiotherapy is an integral part of this recovery process as it aids patients in regaining strength, flexibility, and functional independence.

Why is Physiotherapy Important After Knee Replacement?

Restoration of Movement and Function

Physiotherapy is vital after a knee replacement for several reasons. One primary goal is restoring movement and overall function to the affected knee. Physiotherapists employ targeted exercises and manual therapy techniques to help patients reclaim flexibility and strength in their knee. This enables them to perform daily activities more comfortably.

Prevention of Complications

Physiotherapy can also help prevent complications that might arise following a knee replacement operation. Physiotherapists encourage early mobilization and correct movement patterns, reducing the risk of issues like joint stiffness, muscle weakness, and blood clots.

Pain Management

Managing postoperative pain can be challenging, but physiotherapy offers several solutions. Therapists use various modalities, such as ice therapy, electrical stimulation, and manual techniques, to reduce inflammation and pain. As a result, patients can actively engage in their rehabilitation program and make significant progress toward their recovery goals.

Improving Quality of Life

Ultimately, physiotherapy after knee replacement aims to restore patients’ independence and enhance their overall quality of life. By restoring function, reducing pain, and preventing potential complications, physiotherapy allows patients to return to their favourite activities, paving the way for a better quality of life.

Timeline of Physiotherapy After Knee Replacement

Immediate Post-Operative Phase (First Few Days)

The immediate days following your knee replacement surgery are crucial for setting the pace for your recovery. The focus of physiotherapy during this period is to minimise discomfort and prevent any postoperative complications. Here are the main objectives of this phase:

Alleviate pain and swelling
Prevent complications such as deep vein thrombosis, commonly referred to as blood clots, and pneumonia
Encourage early mobilisation, allowing you to start moving and walking with assistance
Training on how to use assistive devices such as walkers or crutches

You will be gently guided through activities such as ankle pumps and leg raises, sitting at the edge of the bed, standing with assistance, and walking using a walker or crutches.

Early Rehabilitation Phase (First 2-4 Weeks)

As we move into the early rehabilitation phase, physiotherapy aims to empower you with greater mobility and independence in daily activities. The focus is now on:

Increasing the range of motion and flexibility
Strengthening the muscles around the knee joint
Improving balance and muscle awareness (proprioception)
Becoming independent in your day-to-day activities

During this period, you will engage in range of motion exercises for your knee, hip, and ankle, strengthening exercises for your quadriceps and hamstring muscles, balance and proprioception exercises, and gait training with a walker or crutches.

Intermediate Rehabilitation Phase (4-12 Weeks)

Following successful early rehabilitation, we now step into the intermediate phase. Physiotherapy during this period targets:

Further improving range of motion and flexibility
Enhancing strength and endurance
Improving balance and proprioception
Introducing more challenging functional activities

Activities typically include range-of-motion exercises with resistance, strengthening exercises using resistance bands or weights, balance and proprioception exercises on unstable surfaces, and functional activities such as stair climbing and walking on uneven surfaces.

Advanced Rehabilitation Phase (3-6 Months)

In the advanced rehabilitation phase, the objective is to restore full functionality and prepare for a return to regular activities. Physiotherapy focuses on:

Restoring full range of motion and flexibility
Enhancing strength and endurance
Further improving balance and proprioception
Preparing you for your desired activities

You will be introduced to advanced strengthening exercises using resistance machines or free weights, high-impact exercises like jogging or jumping, and sports-specific training if you wish to return to your favourite sports activities.

Long-Term Rehabilitation (6 Months and Beyond)

Rehabilitation does not end once you complete your initial programme. Regular exercise is key to maintaining your progress and preventing future complications. Even six months post-surgery, physiotherapists can offer valuable advice on appropriate long-term exercise programmes, helping you adapt to any changes in your condition over time.

Types of Physiotherapy Exercises After Knee Replacement

Here are some key types of physiotherapy exercises that are commonly recommended after a knee replacement.

Range of Motion Exercises

One of the primary goals following a knee replacement is to regain range of motion. These exercises contribute significantly towards restoring flexibility and preventing stiffness in the joint. The exercises involve moving your knee joint through its full range of motion in a controlled manner. These movements can either be active, done by yourself, or passive, assisted by your physiotherapist. By regularly performing these exercises, you can maintain and even improve the flexibility of your knee.

Strengthening Exercises

A vital part of recovering from a knee replacement is strengthening the muscles around the knee joint, particularly the quadriceps and hamstrings. This fortification not only supports the new knee joint but also helps recover the strength and endurance lost during the surgical procedure and subsequent rest period. Strengthening exercises may involve using resistance bands, weights, or resistance machines to challenge the muscles, helping them regain their original power.

Balance and Proprioception Exercises

Balance and proprioception – awareness of the position and movement of the body – are essential for maintaining stability and reducing fall risk after knee surgery. These exercises could include tasks like standing on one leg, walking on uneven surfaces or using balance boards or foam pads for added challenge.

Aerobic Conditioning

Once your doctor has given you the go-ahead, you should incorporate aerobic conditioning exercises into your physiotherapy routine. Activities such as walking, cycling or swimming are excellent for improving overall cardiovascular health, enhancing endurance, managing weight, and reducing future health complications associated with sedentary lifestyle post-surgery.

Functional Training

Functional training exercises mimic everyday activities and are an integral part of post-operative physiotherapy. These exercises train you to perform common tasks like getting in and out of a chair, climbing stairs, or walking on uneven surfaces with your new knee. Customised to your specific needs and goals, these exercises simulate real-life situations, ensuring a smoother transition back to your regular routine.

Tips for Successful Physiotherapy After Knee Replacement
