Total knee replacement can generally be performed safely when done by a qualified orthopedic team in a properly equipped hospital. However, like any major surgery, it has some possible risks.
The risks are not unique to Bhutan. They can vary based on the patient's health, surgical complexity, hospital facilities, and postoperative care.
1. Infection
An infection can develop around the surgical wound or knee implant. Good sterilization, wound care, and infection-control practices can help reduce this risk.
2. Blood Clots
Blood clots can develop in the legs after surgery. Doctors may use movement, exercises, medicines, or other measures to reduce this risk.
3. Bleeding
Some blood loss is possible during knee replacement. The medical team monitors the patient and manages bleeding when needed.
4. Pain and Swelling
Pain and swelling are common during early recovery. They usually improve with proper pain control, movement, and physiotherapy.
5. Knee Stiffness
Some patients may have difficulty achieving full knee movement after surgery. Early and regular rehabilitation can help improve flexibility.
6. Nerve or Blood Vessel Injury
Injury to nearby nerves or blood vessels is uncommon but possible. The risk can depend on the patient's anatomy and the complexity of the operation.
7. Implant Problems
The implant can become loose, worn, displaced, or damaged over time. Some patients may eventually need additional surgery.
8. Anesthesia Risks
Anesthesia can cause complications, particularly in patients with heart, lung, or other medical conditions. Preoperative assessment helps identify these risks.
Factors Affecting Safety and Recovery
Surgeon Experience
A surgeon's experience with total knee replacement can affect surgical planning, technique, and complication management.
Hospital Facilities
Appropriate operating rooms, anesthesia services, imaging, infection-control systems, and postoperative monitoring are important.
Patient's Health
Diabetes, obesity, smoking, heart disease, infections, and other medical conditions can affect healing and recovery.
Physiotherapy
Regular physiotherapy helps restore knee movement, muscle strength, balance, and walking ability.
Postoperative Care
Proper wound care, pain management, blood-clot prevention, follow-up visits, and rehabilitation can support safer recovery.
Patient Participation
Following medical advice, taking prescribed medicines, completing exercises, and attending follow-up appointments can help improve recovery.
Overall
The main risks of total knee replacement include infection, blood clots, bleeding, stiffness, pain, nerve or blood vessel injury, implant problems, and anesthesia-related complications. Careful patient assessment, experienced orthopedic care, suitable hospital facilities, and proper rehabilitation can help reduce risks and support recovery.
