General use of knee brace

- Dec 16, 2019-

Knee brace is a protective device that is assembled on the outside of the human body to limit abnormal activities through the action of force and maintain the stability of the joint to restore the load capacity of the limb. There are two types of knee braces: fixed braces and hinged braces.

(I) Purpose of use

1. Stability and support: By limiting abnormal mobility, maintaining joint stability to restore the load capacity of the limbs.

2. Fixation function: Promote healing of the affected area by fixing the damaged limb or joint.

3. Protective function: Through the protection of the injured limb, maintain the normal alignment relationship of the limb and ensure the normal function of the limb.

4. Load-bearing function: It can reduce the load of the injured limb and trunk, which is beneficial to the injury.

5.Inhibit muscle reflex spasms during standing and walking

6. Hinged braces can avoid knee flexion dysfunction caused by knee postoperative braking, and resolve the contradiction between rehabilitation exercise and joint braking.

(Two) indications

1. Patients with dislocation of the knee joint.

2. Patella dislocation patients.

3. Patients with knee collateral ligament injury and cruciate ligament injury.

4. Patients after knee meniscus suture.

5. Postoperative fixation of other fractures in the knee joint.

(3) Contraindications

1. Should not be used directly when the affected limb has open wounds, mild allergies, skin damage or ulcers.

2. It is forbidden to use in patients with malignant tumors and bleeding tendencies.

(D) complications

1. Pressure ulcer: It is related to the tight wearing of the brace and the incorrect wearing method.

2. Rash: Long-term direct contact with the skin is related.

(V) Evaluation points

1. Assess patient education level.

2. Assess the overall condition of the patient.

3. Assess the patient's terminal blood flow, bleeding, wound drainage.

4. Assess the patient's skin condition

5. Evaluate the brace and choose the appropriate size.

(6) Main points of the mission

1. Inform patients about the purpose of using knee braces

2. State the key procedures of the knee brace technique to the patient.

3. Demonstrate the wearing method of knee brace to patients

4. Inform the patient to choose the correct size brace to ensure the braking effect

5. Inform the patient that if the affected limb suffers from discomfort such as compression, pain, numbness, etc., inform the nurse in time for treatment.

6. Inform the patient that the angle of the hinge brace cannot be adjusted at will to avoid re-injury of the knee joint.

7. The wearing time of the brace should strictly follow the doctor's instructions, and can not be removed at will.

8. Inform the patient that the brace should be placed horizontally after removal, and compression is strictly prohibited to prevent compression deformation.

9. Inform the patient to check the brace frequently, if there are any open wires or cracks, they should be repaired in time.

10. Inform the patient of the hinged brace to remove the thread and cloth scraps left in the hinge part in time.

11. Inform the patient that if there is discomfort during the whole process of wearing the brace, communicate with the professional in a timely manner.

Key processes

1. Evaluate patients and knee braces

Key points: Check whether the chuck is at 0 ° with hinged braces; check the size and model of braces.

2. Inform patients of the purpose of using knee braces.

3. State the key procedures and methods of wearing the knee brace to the patient.

4. Demonstrate the wearing method of knee joint brace

5. The patient takes a bed or supine position (take supine as an example).

6. The operator straightens the affected limb and lifts it 10 ~ 20cm from the bed.

7. The operator raises the affected limb with one hand and puts the other hand into the knee brace.

8. Fix the restraint bands on the braces separately.

Important: The steel frame of the knee brace should be on both sides of the lower limb.

9. It is advisable that the restraint band is tight enough to fit two horizontal fingers.

Important: Properly secure the drainage bottle and drainage bag, do not discount or take it out. The drainage bottle or drainage bag is placed below the wound.

10. The knee brace is worn.

Important: Cotton clothing is placed in the brace to protect the skin, and the blood flow at the end of the affected limb is closely observed.

11. Ask patients if they feel comfortable.

Key tips

1. Strictly grasp the tightness when wearing the brace and make sure it is properly fixed. Avoid skin abrasion and compression.

2. Patients should pay close attention to the patient's main complaint and vital signs after getting out of bed wearing a brace.

3. When the brace is removed, remove the brace. The operator first lifts the affected limb, removes the brace, and then carefully lowers the patient. During the whole process of wearing and removing, the affected limbs should be kept in an upright position. Someone must protect them so that the affected limbs can maintain the biological line of force.

4. Strengthen protection for patients with weak limb strength and elderly and frail people.

5. In the early period after wearing the brace, attention should be paid to correct the patient's wrong standing and walking posture in time.

6. The affected limb should not bear weight while wearing the brace. Walking sticks should be used to assist walking.
