Journey to a Stronger Knee: Post Knee Replacement Physiotherapy


Knee replacement, also known as knee arthroplasty, is a surgical procedure in which a damaged or diseased knee joint is replaced with an artificial joint, called a prosthesis. This procedure is usually recommended for people who have severe knee pain, stiffness, and limited mobility due to conditions such as osteoarthritis, rheumatoid arthritis, or other knee injuries.

The surgery involves removing the damaged parts of the knee joint and replacing them with metal and plastic components. The artificial joint is designed to mimic the function of a healthy knee, allowing improved mobility and reducing pain.

There are two main types of knee replacement surgery:

  • Knee Replacement (TKR): In this procedure, all three compartments of the knee joint (medial, lateral, and patellofemoral) are replaced with artificial components.
  •  Partial Knee Replacement (PKR): In this surgery, only the damaged part of the knee joint is replaced with an artificial component. This option is suitable for patients who have limited knee damage in specific areas.


  • Pain: Pain is a typical symptom following knee replacement surgery. It is usually most intense in the first few days after the procedure and gradually subsides over time. Pain medications prescribed by the doctor can help manage discomfort during the early stages of recovery.
  • Swelling: Swelling around the knee joint is common after surgery. It is part of the body’s natural healing response. Elevating the leg and applying ice packs can help reduce swelling
  • Stiffness: The knee may feel stiff, especially during the initial phase of recovery. Regular movement exercises and physical therapy are essential to improve flexibility and range of motion.
  • Redness and warmth: Mild redness and warmth around the incision site are normal in the first few weeks. However, if there is excessive redness, heat, or signs of infection, it’s essential to inform the surgeon.                                                        


  • Physical Therapy: Physical therapy plays a central role in knee replacement recovery. A skilled physical therapist will work with the patient to develop a personalized exercise program that helps strengthen the muscles around the knee, improve range of motion, and restore functionality. The therapy typically begins soon after surgery and continues for several weeks or months.
  • Rehabilitation: In addition to physical therapy, rehabilitation involves activities and exercises that promote the knee’s healing and improve mobility. This can include using assistive devices like crutches or walkers during the initial recovery period.
  • Physiotherapy: Physiotherapists will guide patients through a series of exercises to improve the range of motion in the knee joint. These exercises are essential to prevent stiffness and promote flexibility.


Aqua therapy, also known as aquatic therapy or hydrotherapy, is a form of physical therapy that takes place in a pool or other aquatic environment. It involves using the properties of water to facilitate rehabilitation and improve the overall well-being of individuals with various physical conditions.


  • Reduced impact on joints: Exercising in water reduces the weight-bearing load on the knee joint compared to exercises on land.
  • Muscle strengthening: The resistance provided by water makes it an effective medium for strengthening muscles around the knee joint. As patients perform exercises in the water, they encounter resistance in all directions, which helps build strength and stability in the knee and surrounding muscles.
  • Faster recovery: The supportive and low-impact nature of aqua therapy may facilitate a quicker recovery after knee replacement surgery. It can allow patients to start rehabilitation earlier than they might be able to do on land, promoting early mobility and muscle reconditioning.
  • Pain relief: Warm water used in aqua therapy can have a soothing effect and help reduce post-operative pain and inflammation


Knee replacement surgery replaces parts of injured or worn-out knee joints. The surgery can help ease pain and make the knee work better. During the surgery, damaged bone and cartilage are replaced with parts made of metal and plastic.
