Knee Replacement Surgery is also referred as Total Knee Replacement or Total Knee Arthroplasty. This surgical procedure is performed to replace the damaged joint of the knee with an artificial joint which is made from plastic or metal material. These artificial components are called as prostheses. Knee Replacement Surgery is recommended to patients who are suffering from severe pain and loss of function from arthritis and have failed results from other conservative methods of therapy.
Types of Knee Replacement Surgery
There are two types of knee replacement surgery: Total Knee Replacement and Partial Knee Replacement. The type of approach used varies from patient to patient depending upon their condition.
Total Knee Replacement (TKR):- Total knee replacement is a traditional method for repairing the damaged knee. Advancements in medical technology have led to precise and highly functional artificial knee implants which duplicate the functions of the normal and healthy knees. Most total knee replacement surgery involves replacing of the joint surfaces at the end of the thigh bone (femur) and the top of the shin bone (tibia). This surgery also involves replacing the undersurface of the kneecap (patella) with a smooth plastic dome. The artificial implants used are placed in a place with the help of cement. After the artificial implants are fit together the attached artificial parts from the joint, relying on the surrounding muscles and ligaments for support and function.
Partial Knee Replacement (PKR):- Partial Knee Replacement is also referred as uni-compartmental knee replacement surgery. This surgery involves replacing of only a part of the knee in order to preserve as much as the original healthy bone and soft tissues as possible. Partial Knee Replacement surgery is performed in three anatomical compartments of the knee the lateral compartment outside of the knee, the patella femoral compartment outside the knee or in the front of the knee between the thighbone and kneecap. This surgery is generally recommended to patients who have osteoarthritis in only one compartment of their knee.
Types of Approaches for Knee Replacement Surgery
There are different types of approaches for Knee Replacement Surgery. In order to ensure a smooth procedure, the orthopedic surgeon maps out the knee anatomy in advance so that the surgeon can plan their surgical approach and anticipate special instruments or devices which are to be used in the surgery. The knee replacement surgeons in India recommended the type of approach according to the patient’s requirement.
Computer-assisted surgery is a technologically advanced approach used for knee replacement surgery. Many orthopedic surgeons are now turning to computer-assisted methods for both Total Knee Replacement and Partial Knee Replacement surgery. This approach also involves performing both traditional and minimally invasive approaches. In Computer assisted surgery initially the surgeon enters the patient’s anatomical data into the computer and the computer generates a 3-D model of the knee. The software provides the surgeon with a more precise, computer-aided image of the knee which helps the surgeon in aligning the knee components more precisely in the bone. A more precise fit reduces the wear and increases the longevity of the new joint. The computer-assisted approach requires smaller incision which leads to faster recovery, less scarring and less blood loss.
Minimally Invasive approach modifies the techniques used in the traditional approach. Minimally Invasive approach has many advantages over the traditional approach. This approach reduces trauma, less loss of blood, less scarring and faster recovery. Minimally Invasive Knee Replacement Surgery requires 3 to 4 inches of the incision. In this approach, the kneecap is pushed to the side rather than being turned over which results in less trauma to the tissues or the quadriceps muscle. Post-recovery patients experience a better range of motion.
To perform traditional approach for knee replacement, orthopedic surgeon makes an incision of about 8- to 12-inch. Generally, the incision is made along the front and towards the middle or along the front side of the knee. The traditional surgical approach usually involves cutting into the quadriceps tendon in order to turn the kneecap over so the arthritic joint is exposed to the surgeon. The traditional approach for knee replacement required 12 weeks of recovery time.

Knee replacement surgery usually involves removal of severely damaged knee components caused due to arthritis & replacing them with prosthetic knee joint implants. Most often this is useful in decreasing pain while restoring strength & movement in knee.
Orthopedists usually recommend knee replacement surgeries to patients in case they are having stiff & painful knees & which make it difficult for them to perform simple activities even after they have tried various other types of nonsurgical treatments. Knee replacement surgery is generally reserved for people over 50 years of age & suffering from severe arthritis.
Knee replacement surgery is a major surgical intervention which requires that patients be in overall good health & preferably without any other underlying medical conditions or disorders which may eventually cause complications with knee replacement surgery. Orthopedists will advise & inform patients regarding all aspects of treatment after determining that the patient requires knee replacement surgery for his condition. Knee replacement surgery usually begins with administration of general anesthesia so as to avoid pain & discomfort to the patient. Following this, orthopedists would make a long incision in front of the knee. This incision will allow access to the damaged knee joint after the surgeon has shifted aside the muscles, ligaments & tendons. After this, the surgeon would gently remove & scrape damaged bone surfaces in order to shape them in a way to precisely accommodate the prosthetics. Artificial knee joint implants are made quite similar to the natural knee joint & which also works exactly like the original joint. Orthopedists will then attach the right artificial knee joint components to thighbone, shinbone & the kneecap. Medical adhesive or cement is also used so as to hold & fix the implant in the proper place. After the artificial implant components are fixed to their respective places, orthopedist will subsequently assemble the new prosthesis joint in order to check movement & stability of the artificial knee joint before stitching close the incision.
Researchers keep finding newer & innovative methods to perform medical surgeries worldwide. Latest in line for knee replacement surgery techniques is the minimally invasive laparoscopic approach. This involves utilizing special miniaturized surgical instruments which are attached to the laparoscope in order to perform fixing the knee implant during the operation. Laparoscope consists of a system of small & thin flexible surgical tubes which are fitted with a hi-definition video camera & cold source of light along with special miniaturized surgical instruments.
Laparoscopic knee replacement surgery for arthritis requires orthopedic surgeons to make small keyhole incisions around the diseased knee. Orthopedists will first insert the camera-fitted laparoscope through the incision & push inside for it to reach the damaged knee joint. This is to allow the surgeon to check for extent of damage to knee joint on a monitor through this live feed from the laparoscopic video camera. Following this, surgeons will use the attached instruments to clear debris involving broken bone chips as well as any other substances obstructing the knee joint. This is in preparation for having to fit the artificial knee joint with help of medical adhesive. This is an advanced minimally invasive surgical technique which is fast gaining popularity due to a variety of advantages it offers. Most common of these is that laparoscopic knee replacement surgery involves lesser pain & scarring following surgery along with comparatively less amount of time it requires for stay at the hospital & recovery.
