The most commonly reported problem after knee replacement surgery is persistent pain or discomfort. While the surgery is highly effective in relieving the pain caused by osteoarthritis and improving overall mobility, some patients continue to experience discomfort long after the procedure. This can stem from several factors.
One of the main contributors is postoperative inflammation. Swelling and inflammation are normal after surgery, but if not fully managed, they can lead to ongoing pain during the recovery process. Joint stiffness is another frequent issue, as some patients struggle with a reduced range of motion in the knee. This stiffness can be particularly bothersome if the physical therapy regimen is not intense or consistent enough, delaying the recovery of full mobility.
In some cases, the prosthetic implant itself may cause discomfort. This could be due to improper alignment, irritation from the artificial joint, or even loosening of the implant over time. If the implant shifts or doesn’t fit well, it can result in ongoing pain, which may require additional procedures to correct.
Another cause of persistent pain is nerve sensitivity. During surgery, the nerves around the knee can be affected, leading to sensations of numbness, tingling, or hypersensitivity in the area. This can make the knee feel uncomfortable even after the joint has healed.
Lastly, muscle weakness can contribute to pain after knee replacement. The surrounding muscles may take time to regain their strength, and during this process, patients may experience discomfort as the body adjusts to the new joint.
While postoperative pain is common and often temporary, it’s crucial to address it early with appropriate physical therapy, pain management, and follow-up care. In some cases, additional interventions may be necessary to alleviate chronic discomfort. Nonetheless, persistent pain is one of the most frequent challenges faced after knee replacement, and it highlights the importance of a comprehensive rehabilitation plan.
