Total Knee Replacement(tkr) Treatment Doctors in Noida

Total knee replacement (TKR), is a surgical technique performed for the knee joint to replace the damaged joint with a prosthetic implant, eliminating structural and functional deficits and realigning the soft tissues. TKR helps to return to normal biomechanics, increases muscle balance, improves the joint range of motion, and decreases pain, it also helps to improve functionality thus improving the quality of life. The time for recovery and the intensity of treatment depends upon surgical technique and the patient’s condition.

· Total knee replacement or bi-compartmental knee replacement.

· Uni- compartmental (partial) knee replacement

· Kneecap replacement (patellofemoral arthroplasty)

· Complex or revision knee replacement.

Fixation Method used for TKR

1: Cemented

· Used for older or sedentary patients.

2: Porous ingrowth

Theoretically, porous ingrowth fixation should not deteriorate with time, unlike cemented fixation, and is thus the ideal choice for younger or more active candidates.

3: Hybrid technique

· Non-cemented ingrowth femoral and patellar component with a cemented tibial component.

· Frequently used because of failure to achieve fixation with some of the original porous–coated tibial components.

Disabling knee pain with functional impairment and significant bony changes and failed conservative measures are the indications for TKR, these causes may include:

· Rheumatoid arthritis

· Disabling osteoarthritis

· Knee injury

· Knee deformity

· Gout

· Hemophilia

· Pain and loss of cartilage.

Pathology of TKR

Total knee replacement is also known as knee arthroplasty, it is the reconstruction surgery of the arthritic or the damaged knee joint. End of the bone is capped by the metal or plastic material. This surgery is done in patients suffering from severe arthritis or knee injury. The joint cartilage and also the surrounded bone of the knee are damaged. There is inflammation of the synovial membrane and increased synovial fluid, this leads to stiffness and severe pain.

X-RAYS

· X-rays help to determine the extent of joint damaged.

MRI

· MRI helps to determine the bone, muscular or ligamentous damage.

Medication

Bupivacaine, Tylenol, Oxycontin, Toradol (should be taken only if prescribed by the doctor).

The physiotherapist uses the following techniques and modalities for regaining the functionality of the knee joint.

Cryotherapy:

Cryotherapy in combination with PROM exercises, elevation, and massage or compression wrapping is used to decrease edema, developed due to inactivity or loss of voluntary movements.

Thermotherapy:

Thermotherapy can be used in combination with ROM exercises (twice daily) with sustained stretching technique (20 – 30minutes).

Nmes:

Neuromuscular stimulations facilitate voluntary motor control and muscle strength.

Laser:

Cold laser is an effective treatment used for reducing pain thus increase joint range of motion.

Ultrasound:

Ultrasound is decreases pain, increases range of motion, and decreases inflammation.
