This pain can result from surgical inflammation, rehabilitation stress, or soft tissue healing. While mild discomfort is common during recovery, persistent or severe pain may indicate complications like infection or implant issues. Effective rehabilitation focused on gradual quadriceps strengthening and inflammation control is essential. Patients should monitor symptoms and consult their healthcare provider if pain worsens, swelling occurs, or abnormal sensations develop. Early intervention and adherence to physiotherapy protocols support successful healing and knee function restoration.
