Understanding Cracking Knees

Cracking Knees

In orthopedic medicine and sports medicine, the cracking of the knees is called crepitus, which means air is moving in the joint. When the joint is bent, the air bubbles burst, causing a cracking or popping sound. It can also be felt in other joints like the shoulder, elbow, or neck.

People may experience crepitus at any age, but it becomes more common as they age – an era where the bone cartilage starts to weaken and become prone to wear and tear.

Causes of Cracking Knees

Most instances of crepitus are harmless; if the popping or cracking sound comes with pain, it may signify a health problem. Crepitus is sometimes a symptom of the following conditions:

  • Osteoarthritis (OA) – Osteoarthritis is the most common form of arthritis that wastes away the cartilage of the joints, especially in older adults. When the bones rub and grind, it causes pain and stiffness, making mobility difficult. OA mostly happens in the knees.
  • Patellofemoral pain syndrome (PFPS) – PFS causes crepitus and pain behind the kneecap (patella), especially when bending, kneeling, or squatting. It's often due to overuse, misalignment, or imbalance in the muscles supporting the knee and is more common among women than in men.
  • Baker’s cyst - This condition happens when fluid builds up behind the knee, causing a bulge to form. It comes with a tight pain that worsens with activity or when fully straightening or bending the knees. 
  • Tendonitis - Tendonitis is the inflammation of the tendons in the elbows, shoulders, hips, and knees. Tendonitis in the knee is fairly more common than the others and is often a result of repetitive motions that put too much stress on the tendons connecting the patella and shin. 
  • Torn cartilage - Cartilage damage is another probable cause of painful crepitus. The cartilage can be torn as a result of various injuries.

The Role of Vitamins in Joint Health

How Vitamins Can Help

Nutrients and minerals work various roles in the body and ensure optimal function. Not having enough or a lack of certain vitamins may lead to nutrient deficiencies that make one prone to conditions and health problems.

For the joints, mobility becomes strained and less flexible because the synovial fluid inside the synovial joints decreases, making the cartilage thinner and the ligaments shrink. However, dieting or taking supplements with these vitamins can help ensure proper mobility and joint health.

Key Vitamins and Their Functions

These vitamins are best known for their properties that help keep the joints mobile and flexible:

  • Vitamin D – Vitamin D is a nutrient that helps build and maintain healthy bones by regulating the production of phosphate and calcium. It has anti-inflammatory and antioxidant properties potentially reducing the likelihood of cracking sounds due to improved bone and joint integrity.
  • Vitamin C – Vitamin C is essential for preventing inflammatory arthritis and maintaining healthy joints with osteoarthritis. It aids in collagen production, which can enhance the strength and elasticity of joints, potentially lessening cracking.
  • Vitamin E – Vitamin E has high antioxidant properties that protect cells from free radicals in the body. The same properties help combat oxidative stress in the joints, which can contribute to joint discomfort.
  • Vitamin K – Vitamin K is important for the healthy functioning of proteins in cartilage and bone. It acts as an anti-inflammatory agent, which may help it in preventing the onset of osteoarthritis.
  • Glucosamine – A natural compound found in the cartilage, the use of glucosamine in joint-related supplements is mainly based on its anti-inflammatory properties that promote cartilage repair, reduce joint discomfort, and may alleviate joint cracking by maintaining the cushioning properties of joints.
  • Chondroitin: A compound commonly paired with glucosamine, chondroitin helps protect the cartilage in joints by slowing down deterioration, mitigating inflammatory effects, and providing pain relief.  Which could reduce joint cracking by keeping cartilage healthy and intact
  • Omega-3 Fatty Acids (Fish Oil) – Omega-3s are essential fats that offer several health benefits, particularly their antioxidant and anti-inflammatory properties, which may reduce joint stiffness and cracking by improving joint lubrication.
  • Calcium – Calcium is primordial for bone health and formation and can help prevent bone-related health problems like inflammation that might compromise knee joint function.
  • Magnesium – Magnesium is an essential mineral critical to many bodily functions, including bone integrity and muscle function. This mineral helps maintain overall musculoskeletal health and prevents inflammatory conditions. Supports muscle function around joints, potentially reducing cracking by ensuring smoother joint movement.
  • Zinc – Zinc is a nutrient that helps your immune system and is essential for the anti-inflammatory processes. It also stimulates collagen synthesis and improves overall joint health.
  • MSM (Methylsulfonylmethane) –  MSM is a sulfur-rich compound (organosulfur) found in plants, animals, and humans. Often used in joint health supplements, MSM can help reduce inflammation and promote joint comfort and better mobility.
  • Hyaluronic Acid – Hyaluronic acid helps promote cell and tissue growth, ensuring joint cartilage and bone growth and development. It also keeps joints lubricated and maintains joint mobility and comfort.
  • Turmeric – Turmeric is a spice with several health benefits, such as pain relief, lower blood pressure, stronger gut health, and anti-inflammatory properties. Its anti-inflammatory abilities are particularly helpful with people with knee osteoarthritis symptoms and have yielded optimal results.
  • Boswellia Serrata - Boswellia is an ancient herbal extract used as frankincense. It may effectively treat inflammatory conditions like osteoarthritis and rheumatoid arthritis and works as an effective analgesic, protecting joint cartilage from damage and degradation.
  • Collagen – Collagen is a protein made up of amino acids found in the bones, muscles, and blood. It’s mainly responsible for maintaining healthy joints and the integrity of the cartilage. It also provides structural support to the extracellular space of connective tissues.
  • Bromelain – Bromelain is a combination of proteolytic enzyme extracts derived from the stem and fruit of pineapples. It helps treat inflammation and has been commonly used as a pain relief agent for muscular, arthritic, and perineal pain.

Scientific Evidence and Studies

Many studies have backed the efficiency of certain vitamins in reversing joint-related health problems. One study showed that glucosamine can help relieve pain caused by aging-induced osteoarthritis in the joints, while chondroitin helps protect the cartilage in joints.

One trial showed that long-term intake of omega-3 fatty acids enhances anabolic sensitivity to amino acids and hastens recovery from injuries, which can benefit athletes who are prone to injuries that affect the joints. Additional research also shows that MSM can help reduce joint pain and swelling, improve function in people with osteoarthritis, and help prevent cartilage degeneration. 

Magnesium intake was also found to be beneficial in preventing the incidence of knee osteoarthritis. Studies also found that consistent intake of vitamin D-rich foods or supplements benefitted joint health and helped produce calcium. 

Injecting hyaluronic acid into knees affected with osteoarthritis symptoms also helped provide pain relief. A study involving the combination of hyaluronic acid and collagen showed that the two substances produced a synergistic effect and helped improve bone density.

Supplements vs. Natural Sources

While joint supplements may be faster absorbed by the body and or be made to be more highly bioavailable than whole foods, they aren’t meant to substitute for a healthy diet, given that they don’t have all the nutrients present in a full meal and should only act as a supplement – only serving principally to meet nutritional deficiencies.

However in some cases, getting the joint-beneficial nutrients may sometimes not be enough through dietary sources alone. It’s best to combine a proper diet and a healthy supplementation regimen to satisfy your nutritional needs and achieve a good slate of health.

Additional Tips for Healthy Joints


Regular, low-impact exercises like brisk walking, cycling, swimming, and activities like yoga can greatly benefit in maintaining optimal knee health and strength. Leg day exercises like squats and lunges can help knee bending problems by increasing muscular strength and decreasing pressure.

Quit Smoking

Excessive alcohol consumption and smoking cause factors like oxidant stress and cartilage degradation, which all contribute to knee pain and ultimately increase the risk of developing osteoarthritis. Ultimately, it would be better to gradually cut these unhealthy habits to reduce health risks and improve overall health.

Get A Massage

Massages can help improve circulation, reduce pain, and promote relaxation to reduce pain and stress in the knees. It also helps break up scar tissue and improves joint mobility.

Get Enough Rest

Ample rest, both during the day and at night, can help the joints recover from physical stress.
