Arthroscopy and Arthroplasty
Total Knee Replacement
Knee replacement, or knee arthroplasty, is a surgical procedure to replace the weight-bearing surfaces of the knee joint to relieve pain and disability. It is most commonly performed for osteoarthritis, and also for other knee diseases such as arthritis and psoriatic arthritis. Various types of arthritis may affect the knee joint. Osteoarthritis, a degenerative joint disease that affects mostly middle-aged and older adults, may cause the breakdown of joint cartilage and adjacent bone in the knees. Rheumatoid arthritis, which causes inflammation of the synovial membrane and results in excessive synovial fluid, can lead to pain and stiffness.
Anatomy of the knee
The knee consists of the following:
- This is the shin bone or larger bone of the lower leg.
- This is the thighbone or upper leg bone.
- This is the kneecap.
- A type of tissue that covers the surface of a bone at a joint. Cartilage helps reduce the friction of movement within a joint.
- Synovial membrane: A tissue that lines the joint and seals it into a joint capsule. The synovial membrane secretes synovial fluid (a clear, sticky fluid) around the joint to lubricate it.
- A type of tough, elastic connective tissue that surrounds the joint to give support and limits the joint’s movement.
- A type of tough connective tissue that connects muscles to bones and helps to control movement of the joint.
- A curved part of cartilage in the knees and other joints that acts as a shock absorber, increases contact area, and deepens the knee joint.
There are four basic steps to a knee replacement procedure.
- Prepare the bone: The damaged cartilage surfaces at the ends of the femur and tibia are removed along with a small amount of underlying bone.
- Position the metal implants: The removed cartilage and bone is replaced with metal components that recreate the surface of the joint. These metal parts may be cemented or “press-fit” into the bone.
- Resurface the patella: The undersurface of the patella (kneecap) is cut and resurfaced with a plastic button. Some surgeons do not resurface the patella, depending upon the case.
- Insert a spacer: A medical-grade plastic spacer is inserted between the metal components to create a smooth gliding surface.
Two major types of Knee Replacement Surgeries
TKR (Total Knee Replacement)
- The surgery involves the replacement of both sides of the knee joint. It is the most common procedure.
- Surgery lasts between one and three hours.
- Experts say that the implant will last from 15 to 20 years.
- Despite having much less pain and better mobility, there will be scar tissue, which means there will always be some difficulty in moving and bending the knees.
PKR (Partial Knee Replacement)
- This surgery is done when only one side of the knee joint is replaced. Hence, it does not last as long as a total replacement. Less bone is removed, so the incision is smaller.
- PKR is suitable for around one in four people with osteoarthritis. Post-operative rehabilitation is simpler, there is less blood loss, lower risk of infection and blood clots. PKR in general includes a shorter hospital stay and recovery period.
- PKR often results in more natural movement in the knee. Most PKR patients are able to get up and about after their their operation more rapidly than TKR ones.
Our orthopedic trauma surgeons specialize in the treatment of:
- Fractures of the arms, legs and joints
- Reconstruction of the hip and pelvis
- Complex cases of deformity or limb lengthening
- Complications as a result of fracture, such as mal-union (healed fracture deformities) and non-union (unhealed fractures)
- Poly-trauma patients with orthopedic injuries
Orthopedic specialists treat people of all ages, including:
- newborns and children with deformities – such as congenital dislocation of the hip, club foot and scoliosis
- young people who need joint preserving surgery – such as arthroscopic surgery or osteotomy.
- older people with irreversible degenerative joint problems
Some of the most common operations orthopedic surgeons carry out include:
- Repairing Fractured Bones – for more information, you can read about:
– Broken Arm or Wrist
– Broken Ankle
– Broken Collarbone
– Broken Hip
– Broken Leg
– Broken Ribs
