Frame knee in TB hip joint in children is:
- a. premature closure of distal femoral physis due to cast for more than a year
- b. knee stiffness due to plaster
- c. knee stiffness due to muscle fibrosis
- d. knee stiffness due to knee infection.
The answer is (c), knee stiffness due to muscle fibrosis.
Frame knee is a complication of tuberculosis (TB) of the hip joint in children. It is characterized by stiffness and contracture of the knee joint. The exact mechanism of frame knee is not fully understood, but it is thought to be due to a combination of factors, including:
- Muscle fibrosis:
The muscles around the knee joint can become fibrotic due to prolonged inflammation and disuse.
- Capsular contracture:
The capsule of the knee joint can become contracted due to prolonged inflammation and disuse.
- Articular changes:
The articular surfaces of the knee joint can become damaged due to TB infection.
Frame knee can be a difficult condition to treat. Treatment typically involves a combination of physical therapy, occupational therapy, and splinting. In some cases, surgery may be necessary to release the contracture and improve the range of motion in the knee joint.
other options:
The other options are not as likely to cause frame knee:
- (a) Premature closure of the distal femoral physis due to cast for more than a year is more likely to cause growth problems in the leg.
- (b) Knee stiffness due to plaster is more likely to be temporary and resolve once the plaster is removed.
- (d) Knee stiffness due to knee infection is more likely to be caused by a bacterial infection, such as septic arthritis.
