Endoprosthesis of the knee joint
Expert replacement of the knee joint with Zimmer Biomet and Stryker implants. Activation on the day of surgery, minimally invasive techniques and return to active life
Problem: When the knee needs radical help
Advanced arthrosis is not just pain, it is a permanent limitation of your freedom. When the cartilage is completely destroyed, the joint stops working as a shock absorber.
- Chronic destruction (Arthritis stage IV): Cartilage tissue is practically absent. Every movement is accompanied by friction of exposed bones, which causes acute inflammation and excruciating pain, which does not subside even after taking medication.
- Changing the anatomical axis: You notice that the leg is crooked (O-shaped or X-shaped deformity), “clubfoot” or instability appears. This is the result of uneven wear of the joint surfaces, which overloads the back and the other leg.
- Loss of mobility: The knee “locks”, there is night pain, and an ordinary walk becomes a real test. If you plan your route, taking into account the presence of benches for rest, it’s time to act.
“If you notice at least 2-3 symptoms from the list, your joint needs immediate diagnosis to avoid complete loss of mobility”
Technologies: An investment in your activity
We don’t just apply a “patch”, we restore the natural biomechanics of your foot.
- Premium materials: We work with biocompatible alloys, which the body perceives as its own tissue. The combination of titanium, chrome and high molecular weight polyethylene ensures a smooth movement without wear for decades. To restore knee function, we use innovative systems from world leaders: Stryker (Triathlon), Zimmer Biomet (Persona) and Smith & Nephew (Oxinium).
- Personalized selection: Thanks to digital modeling, we take into account the unique features of your anatomy. This allows you to install the implant in such a way that you forget about its presence in a few months.
About the Doctor: Philosophy of functional surgery
My task is not just to replace the joint, but to return you to the quality of life that was 10-15 years ago. In my practice, I use the technique of minimal intervention: we do not cut the muscles, but gently move them apart. This is the key to being able to get back on your feet a few hours after surgery and quickly return to your favorite activities
Preparation: Medical safety protocol
Preparation lasts about 10-14 days and includes a comprehensive examination to exclude postoperative risks:
- Laboratory minimum (7 days before surgery): Comprehensive blood analysis, coagulogram (blood clotting time), glucose level and glycated hemoglobin (important for patients with diabetes), determination of blood group and Rhesus factor.
- Diagnostics of the heart and blood vessels: ECG with interpretation and ultrasound of the veins of the lower extremities (dopplerography) to rule out thrombosis.
- Remediation of foci of infection: Dentist and ENT doctor consultation. Any chronic inflammation must be treated to prevent bacteria from reaching the implant via the bloodstream.
- Correction of therapy: In 5-7 days, it is necessary to stop taking antiplatelet agents and anticoagulants (blood thinners) under the strict supervision of a doctor.
Operation: Technological stage of recovery
Surgical intervention lasts from 60 to 90 minutes and is performed according to a clear algorithm:
- Minimally invasive access: We use technology Subvastus, which allows you to reach the joint without cutting the muscles and ligaments of the extensor apparatus of the knee. This significantly reduces pain after surgery.
- Precision bone processing: With the help of special power systems and templates, the surgeon removes only the damaged layer of bone (about 8-10 mm), forming an ideal bed for the components of the prosthesis.
- Link balancing: This is a critical stage where the doctor checks the tension of the soft tissues. Only with perfect balance will the knee feel like “native”.
- Stable fixation: The components are fixed using high-strength bone cement with the addition of an antibiotic for maximum protection against complications.
Rehabilitation: From the first step to complete freedom
We don’t leave you alone with your new joint.
- Early activation: The Fast Track program allows patients to start moving on the day of surgery. This is the best prevention of complications.
- Go to school: Our rehabilitators will teach you how to properly distribute the load so that the muscles “remember” how to work without pain.
- Constant control: You receive a personalized home exercise program and a schedule of follow-up visits to track your progress.
FAQ: Answers to frequently asked questions
- How reliable is the prosthesis? We use systems with a lifespan of 20+ years. This is actually a “joint for life”.
- Is there an age limit? No. We successfully operate on patients 80+ and 90+ years old, if the heart and lungs allow anesthesia.
- Will the leg hurt after the operation? Postoperative discomfort is easily controlled with modern drugs and disappears within the first weeks. Arthritis pain disappears forever.
- How long does sick leave last? On average 6 to 8 weeks, depending on the nature of your work.
- Will I feel the prosthesis as a foreign body? Most patients stop noticing it after 6-12 months. Light “clicking” during movements is the norm for the mechanism.
- Is it possible to operate with diabetes or pressure? Yes, after appropriate drug preparation and under the supervision of our anesthesiologist.
- What restrictions will remain? Only shock loads (jumping, long-distance running) are not recommended. Walking, swimming, cycling – no restrictions.
- When can you drive? Usually after 4-6 weeks, when the reaction and muscle strength are fully restored.
