Can a knee that has been dented from impact still be treated?

Joint flexibility is key to sitting cross-legged. Insufficient flexibility in the hip, knee, and ankle joints can restrict the range of leg movement, making it difficult to sit cross-legged comfortably. Prolonged lack of stretching and sedentary lifestyles can reduce the elasticity of ligaments surrounding the joints, further limiting mobility. This condition is particularly common among individuals who are physically inactive.

In general, ligament injuries can cause knee pain. Ligament damage is one of the common causes of knee pain. When ligaments around the knee joint are injured, pain of varying degrees usually occurs, often accompanied by symptoms such as swelling and limited mobility. Therefore, when experiencing knee pain and suspecting a ligamеnt injury, strenuous activities should be avoided, and medical attention should be sought promptly to determine the extent of the injury through appropriate examinations.

In general, the inability to bend the leg backward after knee surgery is often related to postoperative scar adhesions, muscle stiffness, limited joint range of motion, delayed rehabilitation exercises, and fear of pain. It can be improved through targeted rehabilitation training, physical interventions, and lifestyle adjustments. If there is no significant progress within 1–2 months after surgery, it is recommended to promptly consult the treating physician.

The synovium of joints can indeed develop hernia-like lesions, medically known as synovial hernias or synovial cysts. These lesions typically form when synovial tissue protrudes outward through a weak area in the joint capsule, and are commonly seen as popliteal cysts (Baker's cysts) behind the knee joint. Most cases are associated with joint degeneration, inflammation, or trauma, while a minority may occur secondary to systemic diseases such as rheumatoid arthritis.

In general, quadriceps tendon injuries can be self-assessed by observing local symptoms, testing knee joint movement, checking muscle strength, pressing on the tendon area, and comparing both sides, which helps to preliminarily determine the extent of injury. After self-assessment, it is recommended to avoid strenuous exercise, reduce weight-bearing on the knee joint, and avoid prolonged standing or walking.

Sudden pain in the right leg causing inability to walk may be caused by intense exercise, accidental sprain, lumbar disc herniation, lower extremity venous thrombosis, knee meniscus injury, or other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under a doctor's guidance. In daily life, pay attention to walking safety, avoid strenuous exercise and excessive fatigue, and wear appropriate protective gear during physical activities to protect the joints.

In general, the main causes of Achilles tendon pain two months after a knee injury include compensatory loading of the lower limb, excessive stretching of the Achilles tendon, tendinitis, retrocalcaneal bursitis, and partial Achilles tendon tear. If discomfort or symptoms occur, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. In daily life, after a knee injury, avoid bearing weight too early and walking prematurely; rehabilitation exercises should be carried out gradually and progressively.

In general, the main causes of discomfort in the right knee—often difficult to describe in terms of specific sensation—include overexertion, knee joint exposure to cold, knee synovitis, chondromalacia patellae, and meniscus injury. If discomfort occurs, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. In daily life, control exercise intensity to avoid overusing the knee joint, and pay attention to keeping the knee warm.
