Persistent knee pain can affect walking, climbing stairs, standing up from a chair and performing everyday activities. For some people, the symptoms develop gradually because of osteoarthritis. For others, previous injuries or other joint conditions may contribute to pain and restricted movement.
When knee pain begins to interfere with daily life, an orthopaedic assessment can help identify the underlying cause and determine which treatments may be appropriate. Knee replacement surgery is one option for selected patients, but it is not necessary for everyone with knee pain. Dr. Omer Sheriff is an knee replacement surgeon in Chennai whose professional practice includes joint replacement and trauma care. This article explains when knee replacement may be considered, the available surgical options, potential risks and the role of rehabilitation.
What is Knee Replacement Surgery?
Knee replacement surgery, also called knee arthroplasty, is a procedure in which damaged joint surfaces are replaced with artificial components. It is commonly considered for people with advanced knee osteoarthritis when pain and functional limitations remain substantial despite appropriate non-surgical treatment.
The knee joint includes the lower end of the thigh bone, the upper end of the shin bone and the kneecap. Damage to the joint cartilage can cause pain, stiffness, swelling and difficulty moving the knee.
During surgery, the surgeon removes selected damaged joint surfaces and places artificial components designed to support joint movement. The procedure and implant selection depend on the patient’s anatomy, the extent of joint damage and the surgical plan.
The aim is to reduce pain and improve function. The degree of improvement varies between individuals, and surgery cannot guarantee complete pain relief or a particular level of mobility.
When May Knee Replacement Be Considered?
Knee replacement may be discussed when symptoms significantly affect daily activities and other suitable treatments have not provided sufficient relief.
A surgeon may consider the following factors:
- Persistent knee pain that interferes with walking, sleep or routine activities.
- Stiffness and reduced movement that affect everyday function.
- Osteoarthritis or other joint damage confirmed through clinical assessment and appropriate imaging.
- Limited improvement after suitable non-surgical treatments.
- The patient’s general health, functional needs and ability to participate in rehabilitation.
Age alone does not determine whether someone is suitable for knee replacement. The decision should consider the condition of the joint, the patient’s symptoms, medical history and the potential benefits and risks of surgery.
Not every painful knee requires an operation. Exercise, physiotherapy, appropriate medication, activity modification and other non-surgical measures may help some patients manage their symptoms.
What are the Different Types of Knee Replacement?
The choice of procedure depends on which parts of the knee are affected and the patient’s clinical assessment.
Total Knee Replacement
Total knee replacement involves replacing the damaged joint surfaces in the main compartments of the knee. It may be considered when arthritis affects multiple parts of the joint and symptoms remain significant despite appropriate non-surgical treatment.
The surgeon evaluates the extent of cartilage damage, joint alignment, stability and overall health before recommending the procedure.
Partial Knee Replacement
Partial knee replacement involves replacing the damaged portion of the knee while preserving the unaffected compartments. It may be suitable for selected patients whose arthritis is limited to one compartment and whose remaining joint structures meet the requirements for this procedure.
Not every patient with knee arthritis is suitable for partial replacement. The decision depends on the location and extent of damage, ligament function and other clinical findings.
Robotic-Assisted Knee Replacement
Robotic-assisted knee replacement uses a computer-based planning system and specialised technology to assist selected stages of the procedure. Depending on the system, it may help the surgeon assess anatomy and plan bone preparation or implant positioning.
The surgeon remains responsible for clinical decisions and performing the operation. Robotic assistance does not eliminate surgical risks or guarantee better results for every patient.
Whether this approach is appropriate depends on the patient’s condition, the surgeon’s assessment and the facilities available.
How is a Patient Assessed Before Knee Replacement?
A preoperative assessment helps determine whether knee replacement is appropriate and how the procedure should be planned.
Medical History and Symptoms
The doctor reviews the duration of knee pain, previous treatments, mobility limitations, existing medical conditions, current medicines and previous operations.
Physical Examination
The examination may assess knee movement, swelling, alignment, ligament stability, tenderness and walking ability.
Imaging
Weight-bearing X-rays are commonly used to evaluate joint-space changes, alignment and the extent of arthritis. Additional imaging may be recommended when clinically indicated.
General Health Assessment
Conditions such as diabetes, heart disease and other medical problems may affect surgical planning and recovery. The care team may recommend investigations or adjustments to existing treatment before surgery.
After reviewing the findings, the surgeon discusses the diagnosis, non-surgical alternatives, proposed procedure, possible complications and expected rehabilitation requirements. Patients should have an opportunity to ask questions before making a decision.
What are the Possible Risks of Knee Replacement?
Knee replacement is a major operation and carries potential risks. These should be discussed with the treating surgeon before surgery.
Possible complications include:
- Infection around the surgical wound or artificial joint.
- Blood clots in the legs or lungs.
- Bleeding or wound-healing problems.
- Persistent pain, stiffness or restricted movement.
- Injury to nearby nerves or blood vessels.
- Implant wear, loosening or the possible need for revision surgery.
- Medical complications related to anaesthesia or existing health conditions.
The likelihood of complications varies according to individual health, the procedure and other factors. Preoperative assessment, appropriate infection-prevention measures, early mobilisation when suitable and follow-up care form part of risk management. However, these measures cannot eliminate every complication.
Patients should seek urgent medical advice if they develop concerning symptoms after surgery, such as increasing redness or discharge from the wound, fever, sudden calf swelling, chest pain or breathlessness.
What is Recovery Like After Knee Replacement?
Recovery takes time and differs from one patient to another. It depends on the type of surgery, general health, preoperative mobility, pain management and progress with rehabilitation.
Immediately After Surgery
The care team monitors the patient and provides appropriate pain management and postoperative care. Walking with assistance may begin early when medically suitable.
Physiotherapy and Exercise
A rehabilitation programme may include knee movement exercises, muscle strengthening, walking practice and activities to improve balance and mobility. The programme is adjusted according to the patient’s progress and the surgeon’s instructions.
Returning to Daily Activities
Some daily activities can be resumed gradually as strength and mobility improve. The timing varies, so patients should follow individual guidance rather than rely on a fixed recovery schedule.
Follow-Up Appointments
Follow-up visits allow the surgeon to review wound healing, pain, movement and functional progress. Patients should report persistent or worsening symptoms rather than assuming that all discomfort is part of normal recovery.
Successful rehabilitation involves active participation from the patient and appropriate guidance from the treating team. Results cannot be predicted precisely for every individual.
How Can Knee Health Be Managed Before Surgery?
Patients who are considering knee replacement may benefit from discussing non-surgical management with their doctor.
Depending on the diagnosis, these measures may include:
- Strengthening exercises and physiotherapy.
- Suitable low-impact physical activity.
- Weight management where appropriate.
- Activity modification to reduce aggravating movements.
- Medication selected according to the patient’s health and medical history.
- Supportive devices when recommended.
These measures may help manage symptoms and maintain function. Their effectiveness varies according to the severity of joint damage and the patient’s individual circumstances.
