Do you really need to replace the entire joint when arthritis only affects a single area of your knee?
Those individuals whose arthritis is confined to a single compartment of the knee have the option of undergoing a procedure known as partial knee replacement, also known as unicompartmental knee arthroplasty (UKA). This procedure features bone and tissue preservation.
A partial knee replacement is an option to total knee replacement (TKR) that is less intrusive and allows for a quicker recovery time. This procedure is used when arthritis only affects one section of the knee. The damaged compartment, whether it be the medial, lateral, or patellofemoral, is the only one that is replaced during this surgery. Healthy bones, ligaments, and joint structures are still preserved. UKA is an appealing option for a significant number of patients since it involves fewer incisions, less postoperative pain, and a more expedient recovery process.
What Is a Partial Knee Replacement?
The arthritic portion of the knee is the only part of the knee that is resurfaced with metal and plastic implants during a partial knee replacement procedure.
Since healthy areas of the knee are not affected, the natural ligaments are prevented from being damaged. When compared to full knee replacements, partial knee replacements usually result in less injury to the patient during surgery, shorter operating periods, and a more rapid recovery.
The indications – What Kind of Person Should Use It?
UKA is perfectly suited for people who-
The osteoarthritis is restricted to a single compartment, particularly the medial compartment. The range of motion should be preserved while maintaining excellent ligament function.
If they are between the ages of 40 and 80, do not have morbid obesity, and have tried non-surgical therapy but failed. Do not suffer from inflammatory arthritis, significant deformities, or damage to the ligaments.
What are the benefits of Partial Knee Replacement?
There are many benefits related to partial knee replacement.
- The incision is smaller, resulting in less damage to the soft tissue and reduced blood loss.
- A faster recovery time is approximately half of the time required for total knee replacement (TKR), with patients being able to resume desk work in approximately two weeks.
- A better range of motion, a more natural walk, and increased patient satisfaction are all possible outcomes of improved knee function.
- When compared to full replacements, there are fewer instances of infections, clots, and problems.
- Shorter hospital stays and a quicker return to activity are both cost-effective measures.
An Overview of the Surgical Procedure
When performed under general or regional anesthesia, the procedure normally lasts between one and two hours. After making a small incision, the surgeon removes the injured bone and cartilage from one compartment and then implants metal and polyethylene surfaces where they were previously located.
The use of computer-assisted navigation and robotic-arm navigation alternatives (such as MAKO and CORI) is becoming increasingly common to improve the accuracy of bone preparation and implant location.
The process of recuperation and rehabilitation
It is possible to achieve immediate mobility by beginning walking and physiotherapy on the same day. NSAIDs, nerve blocks, and opioids are used in moderation for pain management.
The treatment plan consists of strength training and joint exercises for a period of six weeks. From one to two weeks, light activities can be resumed, and by six to ten weeks, moderate activities such as golf can occur.
The majority of patients gain complete functional recovery within 3 to 6 months after their first diagnosis.
What are the Potential Risks and Issues
With a lower risk than total knee replacement, UKA still carries the possibility of complications.
- Infections, blood clots, and the dangers of anesthesia
- Implant loosening, persistent discomfort, and stiffness are all symptoms.
- TKR may be necessary in the future for arthritis that affects other compartments.
- The risk of revision surgery is around 8% during a period of 5 years, which is higher than the risk related to total knee surgery, while the outcomes remain comparable.
Innovations in the Partial Knee Replacement
Robotic Assistance
Studies have shown that robotic technologies bring about improvements of up to 5% to 10% in placement accuracy and alignment, as well as a reduction in revision rates.
Computer-Guided Surgery
CAOS is a form of computer-assisted operation that improves precision through the use of CT, fluoroscopic, or sensor-based imaging.
Innovations in implant
Improved materials, mobile-to-fixed bearing options, and modern cemented and cementless designs are all examples of how prostheses are evolving to decrease damage and increase longevity.
Importance of Choosing the Right Surgeon
A partial knee replacement depends on more than just high-tech equipment; it also depends on how skilled the surgeon is. Choosing an expert who does UKA regularly guarantees a correct diagnosis, the right choice of implant, and a speedy recovery. A skilled surgeon makes results much better, lowers risks, improves long-term joint function, and makes patients happier.
Wrapping It Up
The Partial Knee Replacement procedure provides a targeted and less invasive treatment option for patients who suffer from arthritis that is confined to a single compartment of the knee. Because of its compelling benefits, it is an excellent option for patients who are eligible.
Further advancements in robotics and computer-assisted technology continue to improve the precision and efficiency of UKA products. If you are thinking about having your knee replaced, you should consult with an orthopedic specialist to find out whether or not a partial knee replacement is the best option for you.
