Introduction

After surgery for patellar fracture, knee flexion can be exercised through methods such as assisted bending with external force, supported squatting, self-applied pressure for bending, flexion and extension exercises, and walking. If any physical discomfort occurs, it is recommended to seek medical attention promptly. In daily life, it is advisable to consume more foods rich in protein, multiple vitamins, minerals, and other nutrients to supplement the body's energy needs and help maintain overall health.

In general, after patellar fracture surgery, knee flexion can be exercised through methods such as externally assisted bending, supported squatting, self-pressure bending, flexion-extension exercises, and walking. If any physical discomfort occurs, it is recommended to seek medical attention promptly. Specific analysis is as follows:

1. Externally Assisted Bending

Prolonged inactivity may lead to joint stiffness. Flexion exercises with external assistance can help improve blood circulation around the knee joint, increase oxygen and nutrient supply, and promote cellular repair and regeneration.

2. Supported Squatting

After patellar fracture surgery, muscles and soft tissues surrounding the knee may develop adhesions, leading to joint stiffness and limited mobility. Supported squatting effectively stretches the muscles and soft tissues around the joint, helping prevent and reduce adhesions, thereby promoting recovery of joint function.

3. Self-Pressure Bending

Once the fracture site has stabilized and casts or braces have been removed, patients may perform self-pressure bending under a doctor's guidance. Appropriate pressure can stimulate blood flow to the fracture area, promoting bone tissue growth and healing. Therefore, self-pressure bending can be used after patellar fracture surgery to exercise knee flexion.

4. Flexion-Extension Exercises

Flexion-extension exercises are crucial for restoring knee flexion after patellar fracture surgery, as callus formation during the healing process may cause joint stiffness. These exercises enhance joint range of motion and flexibility, help restore muscle strength and endurance, and prevent muscle atrophy and joint stiffness.

5. Walking

If the fracture site has stabilized and the doctor determines that mild activity is appropriate, walking can be used to exercise knee flexion. During walking, the muscles surrounding the knee joint are engaged, which helps strengthen muscles and improve joint stability.

In daily life, it is recommended to consume foods rich in protein, vitamins, minerals, and other nutrients—such as eggs, lean meat, tomatoes, apples, etc.—to provide necessary energy and support overall health.

What are the causes of knee pain when bending?

The knee may refer to the knee joint. Pain during knee flexion could be caused by factors such as prolonged posture maintenance, environmental irritation, arthritis, meniscus injury, or synovitis. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Patients are advised to drink plenty of warm water and consume nutrient-rich foods such as eggs and milk in moderation.

Can genu valgum at age 20 still be corrected?

In general, genu valgum at age 20 can be corrected. Mild cases can usually be corrected non-surgically, while moderate to severe cases may require surgical intervention. To maintain knee joint health and support correction of genu valgum, it is recommended to avoid prolonged knee flexion and standing on tiptoes in daily activities, and to wear comfortable shoes that reduce stress on the knee joints. Additionally, consistent and appropriate lower limb exercises should be performed to strengthen muscle strength.
