How to Treat a Sports Injury Immediately When It Happens
Read MoreKnee replacement surgery, also known as knee arthroplasty, is a common and effective procedure for individuals suffering from chronic knee pain and reduced mobility due to arthritis, injury, or other degenerative conditions. This surgery can significantly improve a person’s quality of life by reducing pain and restoring mobility. In this blog, Dr Ankit Dave — one of the best knee replacement surgeons in Nairobi — explains the different types of procedures, the surgical process, and how to care for yourself post-surgery to achieve the best outcomes.
Types of Knee Replacement Surgery
There are several types of knee replacement surgeries, each tailored to specific conditions and levels of knee damage. The type recommended will depend on the patient’s age, activity level, and the severity of joint damage.
- Total Knee Replacement (TKR)
- In total knee replacement, the entire knee joint is replaced with artificial components made of metal, ceramic, or plastic.
- This is the most common type of knee replacement surgery and is often recommended for individuals with advanced arthritis or extensive joint damage.
- Partial Knee Replacement (PKR)
- In partial knee replacement, only the damaged portion of the knee is replaced, preserving the healthy parts of the joint.
- PKR is less invasive than TKR, requires a shorter recovery time, and is usually an option for patients with damage limited to one part of the knee.
- Kneecap Replacement (Patellofemoral Replacement)
- This procedure involves replacing only the undersurface of the kneecap and the groove it rests in.
- It is recommended for patients with arthritis limited to the kneecap.
- Revision Knee Replacement
- This is performed when a previous knee replacement fails due to wear and tear, infection, or other complications. It involves replacing the original implant with a new one.The Knee Replacement Procedure
1. Pre-Surgery Preparation
Being one of the best orthopaedic surgeons in Nairobi, Dr. Ankit Dave explains that your doctor will conduct a series of evaluations before undergoing surgery to determine if knee replacement is the right solution for you. This may include:
● Medical history and physical examination.
● Imaging tests like X-rays or MRI to assess joint damage.
● Blood tests and other pre-operative screenings to ensure your fitness for surgery.
You may also be advised to stop certain medications, quit smoking, and lose weight (if necessary) to reduce surgical risks and promote faster recovery.
2. The Surgery
Knee replacement surgery is typically performed under regional anesthesia (spinal or epidural) or general anesthesia. The procedure involves:
● Making an incision over the knee to access the joint.
● Removing damaged cartilage and bone from the knee joint.
● Placing and securing the artificial components (prosthesis).
● Closing the incision and bandaging the knee.
The entire procedure usually lasts 1–2 hours.
3. Hospital Stay
After surgery, you’ll be closely monitored in the recovery room before being moved to a hospital ward. Most patients stay in the hospital for 1–3 days, depending on the type of surgery and their overall health.
Post-Surgery Care
Recovering from knee replacement surgery in Nairobi requires a combination of physical therapy, pain management, and lifestyle adjustments. Here’s what you can expect and how to ensure a smooth recovery:
1. Pain Management
● It’s normal to experience pain and swelling after surgery. Pain medications, anti-inflammatory drugs, and ice packs can help manage discomfort.
● Your doctor may also prescribe blood thinners to prevent blood clots.
2. Physical Therapy and Rehabilitation
● Physical therapy is a critical part of recovery. A physiotherapist will guide you through exercises to strengthen your leg muscles, improve flexibility, and regain mobility.
● Rehabilitation typically begins the day after surgery, with gradual progression to walking and more complex exercises.
3. Preventing Complications
● To avoid blood clots, your doctor may recommend wearing compression stockings, using a continuous passive motion (CPM) machine, and staying as active as possible.
● Watch for signs of infection, such as fever, increased swelling, redness, or drainage from the surgical site, and report them to your doctor immediately.
4. Lifestyle Adjustments
● Use assistive devices like crutches, a walker, or a cane as recommended during the initial recovery phase.
● Avoid high-impact activities like running or jumping. Focus on low-impact exercises like swimming, cycling, or walking to stay active without putting stress on the knee.
● Maintain a healthy diet to support healing and maintain a healthy weight to reduce stress on the knee joint.
5. Follow-Up Appointments
● Regular follow-ups with your surgeon are essential to monitor your progress and ensure that the artificial joint is functioning properly.
● Most patients regain full mobility within 3–6 months, but recovery timelines can vary.
Benefits of Knee Replacement Surgery
For most patients, knee replacement surgery leads to significant improvements, including:
● Reduced or eliminated pain.
● Improved mobility and quality of life.
● The ability to resume daily activities and enjoy recreational pursuits.
The best orthopaedic surgeons in Nairobi, including Dr Ankit Dave, share the positive sentiment about advancement in surgical techniques and prosthetic designs. They have made knee replacements more durable, with many lasting 20 years or longer.
