Feeling clicking or popping after a knee replacement is common and usually harmless. It often comes from the movement of the artificial components or soft tissues adjusting to the new joint. As swelling reduces and strength improves, the sensation often fades. However, if the clicking is painful, accompanied by swelling, or causes instability, it’s best to check with your surgeon or physiotherapist.

After knee replacement surgery, restoring your range of motion (how well your knee bends and straightens) is essential for everyday function and long-term recovery. Limited motion, or stiffness, affects around 6.1% of patients and can lead to further procedures like manipulation under anaesthesia or revision surgery. These complications significantly increase treatment costs—up to 7.5 times more than for patients without stiffness. Early and consistent physiotherapy, combined with following your rehab plan, is key to maintaining good motion and avoiding costly setbacks.

While total knee replacement (TKR) is a common treatment for knee osteoarthritis, it's not always necessary—and carries risks like complications and dissatisfaction. Evidence-based alternatives such as Physiotherapist guided exercise and lifestyle programs offer effective non-surgical options.
