Knee replacement surgery can be life-changing, helping people regain mobility and reduce pain caused by arthritis or injury. However, while modern knee replacements are designed to last many years, some individuals may require knee revision surgery.
If you’ve had a knee replacement and are experiencing problems, understanding why knee revision surgery may be necessary is essential.
What could cause a knee replacement failure?
Your surgeon should help you understand why your knee replacement has failed. Many factors can contribute to a failed knee replacement, leading to the need for revision surgery. If you’re wondering, what is the most common reason for knee revision surgery? we have detailed some of the causes below:
- Implant loosening: Over time, an implant can become detached from the bone due to wear, stress, or poor initial fixation. This leads to pain, instability, and difficulty walking.
- Implant wear and tear: Frequent use and natural ageing of the implant can lead to deterioration, particularly in younger or more active patients.
- Infection: Bacterial infections can cause swelling, pain, and stiffness, often requiring revision surgery to remove the infected implant.
- Fractures around the implant: Trauma, osteoporosis, or accidental falls can cause fractures near the implant, compromising its stability.
- Instability or dislocation: Weak ligaments or improper implant positioning can lead to knee instability, making movement difficult and increasing fall risks.
Symptoms of a failed knee replacement
If you experience any of the following symptoms after a knee replacement, it may be time to consult your orthopaedic specialist:
- Persistent pain or discomfort that doesn’t improve with time
- Swelling and redness around the knee
- Difficulty bearing weight or walking
- A sensation of instability or the knee “giving way”
- A noticeable change in the alignment of the knee
Benefits of a knee revision surgery
Knee revision surgery offers several benefits, primarily by alleviating pain, restoring mobility, and improving overall joint function. For those experiencing severe discomfort or instability, the procedure can provide significant relief from symptoms that affect daily life.
Additionally, undergoing revision surgery at the right time can prevent further complications and the need for even more extensive procedures in the future, ultimately serving as a cost-effective solution by reducing the likelihood of repeated surgeries.
How a knee revision surgery is operated
Knee revision surgery is a complex procedure that requires precision and expertise. The patient is typically placed under general or spinal anaesthesia and positioned on their back with the leg secured to ensure stability.
The surgeon begins by making an incision over the knee to access the joint. The old implant and any damaged bone or scar tissue are carefully removed. If necessary, bone grafts or metal augments are used to reinforce the remaining bone structure.
Once the area is prepared, a new prosthetic implant is inserted and secured in place. The surgeon then checks the alignment and stability before closing the incision with sutures or staples. The knee is then bandaged, and a drain may be placed to prevent fluid buildup.
How long a knee revision surgery will take
Some knee revision surgeries can last for an hour, while other patients can be in theatre for a few hours, depending on the complexity of the procedure. Factors such as the extent of bone damage, the presence of infection, and the type of implant being used can affect the duration.
Knee Revision Surgery Recovery and Timeline
The total recovery time for knee revision surgery can take between six months to a year, but each individual is different. Your surgeon will guide you through your recovery, but key milestones can include:
- First Few Days: Patients typically stay in the hospital for several days to monitor pain, prevent infection, and begin light physiotherapy.
- Week 1-2: Swelling and stiffness are common. Patients use mobility aids like crutches or walkers and start gentle movement exercises.
- Weeks 3-6: Gradual improvement in mobility and strength.
- Months 2-3: Most patients can walk with minimal assistance, and pain levels decrease significantly.
- Months 4-6: The knee continues to strengthen, and patients can return to low-impact daily activities.
- Months 6-12: Full recovery varies by individual, but by the one-year mark, most patients regain near-normal function and mobility.
Rehabilitation is crucial for successful recovery. Regular physiotherapy, following exercise plans, and attending follow-up appointments with the surgeon can help ensure the best outcome.
