The knee joint is the most complicated joint of the body. It consists of three components junction of three bones: the patella (knee cap), distal femoral condyles(thigh bone) and the proximal tibial plateau (leg bone). The ends are covered with articular cartilage- an elastic material that allows the knee to move freely. If damaged, the cartilage cannot repair itself.
Post traumatic Arthritis
Pain in Deformed Knee
Osteoarthritis most commonly referred to as the wear and tear of the joint usually affects the elderly and middle age to elderly people.
In osteoarthritis the cartilage between the joint breaks down.
Previous traumatic joint injury/overuse of joints
Pain in and around the joint
Difficulty in squatting and sitting crossed leg
Difficulty in negotiating stairs
Deformities of the joint
Inability to walk for long distances
Decreased movement of the joint
History and clinical examination
Standing X rays of the knee joint
Some patients may knee CT Scan/ MRI
The surgical treatment becomes an option in severe cases and the medical treatment fails.
Medical treatment includes
Surgical Indications are
When the medical treatment fails to relieve the pain
There is severe deformity of the joint so much so that it affects the daily activities of the patient
There is instability of the knee joint
There is decreased range of motion of the joint
Knee replacement surgery is a procedure that decreases the pain and improves the quality of life. During total joint replacement surgery, the worn-out surfaces of the joint are removed/shaved off and replaced with implants. The femoral(thigh bone) and tibial(leg bone) component is made up of a metal alloy that covers the end of these bones. The insert/spacer that is put between the two metal components serves as a cushion, a smooth gliding surface between the two.
The patella (knee cap) is resurfaced with a special polyethylene.
The surgeon will supervise the knee rehabilitation programme, which usually begins 24-hours after the surgery.
Isometric quadriceps exercises are started 24 hours after the surgery
The patient is allowed bed side sitting 24 hours after the surgery
The patient is made to stand on the next day of surgery
The patient is made to walk with the help of walker 48 hours after the surgery.
Knee bending exercises are started 48 hours after the surgery
Patient walk with the aid of walker up to 6 weeks
After 6 weeks walker is replaced with stick for next 6 weeks
Patient walks unaided after 3 months
The knee physiotherapy is continued for 6 months after the surgery.
