Introduction
The tendons behind both knees usually refer to the tendons in the popliteal fossa. Soreness and fatigue in these tendons may result from physiological factors or pathological conditions, such as calcium deficiency or ligament strain, which require prompt treatment. Besides these causes, it could also be due to a popliteal cyst. Regardless of the specific cause, some local damage is likely to occur; therefore, timely medical attention is necessary.
The tendons behind both knees usually refer to the tendons in the popliteal area. Soreness and fatigue in these tendons may result from physiological factors, or they could be caused by pathological conditions such as calcium deficiency or ligament injury, which require prompt treatment. Specific causes are as follows:
1. Physiological Factors
If you've engaged in intense exercise or heavy physical labor, lactic acid can accumulate in muscles throughout the body, leading to soreness. This discomfort can be relieved through adequate rest and local massage.
2. Pathological Factors
1) Calcium Deficiency
Calcium is an essential nutrient required for maintaining normal nerve and muscle function. A deficiency in calcium may lead to excessive nerve excitability, causing muscle cramps, generalized weakness, and pain. Treatment may include taking medications such as compound calcium gluconate oral solution, calcium acetate tablets, or calcium carbonate D3 granules, under a doctor's guidance.
2) Ligament Injury
Ligament injuries in the knee can occur when external forces during physical activity or labor push joint movement beyond its normal range, resulting in symptoms such as swelling, pain, and joint deformity. Medications like ibuprofen sustained-release capsules, diclofenac sodium sustained-release tablets, or acetaminophen sustained-release tablets may be taken as prescribed. In more severe cases, arthroscopic minimally invasive surgery may be recommended.
Besides the above causes, other possible reasons include rheumatoid arthritis, gout, or popliteal cysts. Regardless of the cause, these conditions can cause localized damage; therefore, timely medical consultation is crucial to avoid delaying optimal treatment.
