While mild stiffness and discomfort are common, excessive scar tissue can limit knee mobility and cause persistent pain. Most patients improve with early and consistent physiotherapy, which promotes flexibility and reduces scarring. Persistent symptoms beyond 12 months may require medical evaluation to prevent complications. Proactive management, including customised exercises, weight management, and adherence to post-operative care, is key to minimising scar tissue impact. Severe stiffness, swelling, or pain after three months should prompt consultation with healthcare providers to explore interventions. Early rehabilitation and professional support help ensure optimal long-term function and comfort following knee replacement surgery.
