Partial knee replacement surgery procedure is an ideal alternative to total knee replacement procedure for patients having osteoarthritis of the knee where damage is confined to a particular compartment of the knee joint. Earlier, partial knee replacement surgery procedure was reserved for older patients who were generally involved in fewer activities. With better & newer implants & improved surgical interventions, more & more patients are now considering partial knee replacement surgery nowadays. It is estimated that about 5 – 6 percent of arthritic knee patients are eligible for partial knee replacement procedures. Moreover, it is believed that about 30 percent of the general population is having knee osteoarthritis. Knee osteoarthritis below 50 years of age is equally common among men & women. However, after 50 years of age more women are found to be affected by osteoarthritis.
What is Osteoarthritis?
Osteoarthritis of the knee is basically wearing-off of connective tissue known as articular cartilage found within the knee joint. Articular cartilage is meant to effectively prevent one bone from scraping over the other in a joint formation during movement. This cartilage also acts like a shock absorber in the joint while allowing for smooth & stable movement of the joint. Joints get inflamed when cartilages thin down & patients subsequently feel stiffness & pain in joint alongside limiting range of motion.
What is Partial Knee Replacement Surgery Procedure?
Partial knee replacement surgery procedure is a surgical intervention which only replaces the damaged portion of the knee cartilage & joint with an artificial implant.
Advantages of Partial Knee Replacement Surgery Procedure
When compared with total knee replacement, partial knee replacement surgery is able to better preserve function & range of motion of knee mainly because it retains the healthy tissue & bone within the knee joint. This is one reason why patients tend to be more satisfied with the partial knee replacement procedure as compared with the total knee replacement surgery. Another advantage for the patient is that they even after undergoing partial knee replacement surgery they are still good candidates to avail total knee replacement surgery in future, in case they need one. Moreover, there is also lesser loss of blood during the surgical intervention & range of motion of the knee joint recovers much faster with the partial knee replacement procedure.
Ideal Candidates for Partial Knee Replacement Surgery Procedure
Ideal candidates for partial knee replacement surgery are people with lateral, medial or patellofemoral knee osteoarthritis. While ‘lateral’ refers to the outside compartment which is farthest from the opposite knee, ‘medial’ refers to the inside compartment of the knee joint. Medial knee osteoarthritis is normally caused by damage to knee cartilage & which is commonly known as meniscus tear. Patellofemoral osteoarthritis is basically osteoarthritis of the knee joint between patella the kneecap & tibia the lower leg bone. This is a type of osteoarthritis which is more common than lateral knee osteoarthritis.
Criteria for Undergoing Partial Knee Replacement Surgery
When knee pain is found to persist despite maintaining healthy body weight & use of anti-inflammatory medications, people may want to consider knee replacement surgery as an option. Doctors will generally ask patients to identify exact area of pain in knee & then also check the range of motion & stability of the knee. An x-ray of the knee will then determine if the patient is eligible for partial knee replacement surgery. However, the orthopedic surgeon will not know for certain if a patient is a good candidate for partial knee replacement until he has begun with the operation. Ideal candidates for partial knee replacement must have limited inflammation, sufficient range of motion in knee joint, intact anterior cruciate ligament, damage to only one compartment, minimal pain at rest & without calcification of cartilage or dislocation of the knee joint so as to qualify for this procedure. Partial knee replacement surgery was earlier considered ideal only for patients who are above 60 years of age & lived a sedentary lifestyle. However, nowadays younger & more active patients are also increasingly being considered for partial knee replacement surgery.
Partial Knee Replacement Success Rates & Recovery
Success rates of partial knee replacement surgery procedure largely depend upon how well patients follow instructions given by orthopedists regarding aftercare. However, patients can start moving the knee on the day after undergoing surgery. Moreover, knee function should rapidly return with less pain than it would have been after total knee replacement surgery. Partial knee replacement surgery patients will also have to work with physical therapists in order to mobilize the knee while they are still in the hospital & subsequently for 2 – 4 weeks of time following discharge. Discharge from the hospital usually occurs after 1 – 2 days following surgery. Patients will however also require medications to guard them against formation of blood clots while they are in the hospital & then perhaps for a period of time following discharge. Most partial knee replacement surgery patients are usually back, to full activity in about 30 days of time. Jogging or running or impact exercises are normally not recommended simply because partial knee replacement surgery typically includes a bearing surface which can wear-off.
Risks & Complications Involved with Partial Knee Replacement Surgery
Risks & complications which are associated with partial knee replacement surgery procedure include infection at surgical site, formation of blood clots & injuries to nerves or blood vessels. Although these complications are rare, some patients may experience stiffness within the knee joint. Late complications of partial knee replacement include infection, failure, dislocation or loosening of the prosthesis along with continued pain.
