Ever Wonder Why Your Knees Creak?
Maybe you’ve heard someone say, “My knees aren’t what they used to be,” or noticed a strange popping sound when you stand up. Most of us don’t think much about what’s happening inside our joints—until they start giving us trouble. But did you know that a big part of your joint comfort comes down to a thin, flexible tissue called cartilage?
Cartilage is one of those things you don’t miss until it’s gone. But with a little know-how, you can keep yours in good shape for years to come.
What Exactly Does Cartilage Do?
Think of cartilage as the cushion or shock absorber in your joints. Imagine your joints are like the hinges on a door—without a soft pad, the metal would grind and wear out quickly. Cartilage acts as that pad, letting your bones move smoothly against each other without pain or damage.
There are actually a few types of cartilage in your body, but when we talk about your knees, hips, or shoulders, we’re usually talking about articular cartilage—the tough, rubbery layer that covers the ends of your bones. Without it, even simple movements like walking or typing could feel stiff and painful.
Cartilage doesn’t have its own blood supply, which makes it slow to heal if it gets damaged. That’s why protecting it is so important.
3 Cartilage Problems You Shouldn’t Ignore
- Osteoarthritis (Wear-and-Tear Damage): This is the most common cartilage problem. Over time, or from repeated strain, the cartilage in your joints can break down. When that cushion gets thin or rough, your bones start to rub together, causing pain, swelling, and stiffness. If ignored, it can make everyday tasks—like climbing stairs or opening jars—much harder.
- Cartilage Tears: Sudden injuries, like twisting your knee during sports or a fall, can cause the cartilage to tear. These tears can cause sharp pain, swelling, and even a feeling like your joint is “catching” or locking up. Left untreated, tears can lead to chronic pain and early arthritis.
- Inflammation (Chondromalacia): Sometimes, the cartilage softens and becomes inflamed, especially under the kneecap. This is common in young athletes or people who overuse their joints. It leads to aching pain, grinding sensations, and may make it tough to kneel or squat. If you keep pushing through the pain, the damage can get worse and harder to fix.
Cartilage Health: Separating Myths from Facts
- Myth: “Once cartilage is damaged, there’s nothing you can do.”
Truth: While cartilage doesn’t heal as quickly as other tissues, you can slow down damage, reduce pain, and sometimes even help it repair with the right care. The earlier you take action, the better your chances. - Myth: “Only older people need to worry about cartilage.”
Truth: Young people, especially athletes or anyone with repetitive joint stress, can have cartilage problems too. Starting healthy habits early can protect your joints for life.
6 Simple Ways to Protect Your Cartilage Starting Today
- Keep Moving, But Mix It Up: Gentle, low-impact exercise—like swimming, biking, or walking—keeps your joints flexible and healthy. Movement helps deliver nutrients to your cartilage, which it needs since it doesn’t get direct blood flow. Try 30 minutes a day, most days of the week, but switch up your activities to avoid overusing the same joints.
- Maintain a Healthy Weight: Every extra pound puts more pressure on your knees and hips, speeding up cartilage wear. Shedding even a small amount of weight takes a big load off your joints. Aim for gradual, steady weight loss through a mix of healthy eating and activity.
- Strengthen the Muscles Around Your Joints: Strong muscles act like shock absorbers, taking stress off your cartilage. Focus on exercises that build muscle in your legs, hips, and core. Try simple bodyweight moves like squats or wall sits 2-3 times a week.
- Stretch Regularly: Flexible muscles keep your joints moving smoothly and prevent strain on the cartilage. Gentle stretching after your workout, or even during TV commercials, can help. Hold each stretch for 20-30 seconds.
- Protect Yourself from Injury: Use proper form when you exercise or lift. Wear the right shoes and safety gear. Avoid “weekend warrior” overload—trying to cram a week’s worth of activity into one day can set you up for cartilage tears.
- Eat for Joint Health: Foods rich in vitamin C (like oranges and bell peppers), omega-3s (like salmon and walnuts), and antioxidants support cartilage repair and reduce inflammation. Add a colorful variety of fruits, veggies, and healthy fats to your meals every day.
Warning Signs It’s Time to Talk to a Doctor
- Persistent Joint Pain or Swelling: If your joint pain or swelling lasts more than a week or keeps coming back, it could be a sign of cartilage damage that needs medical attention. Waiting too long can let the problem get worse.
- Joint “Locking” or Giving Out: If your knee or another joint suddenly locks in place, catches, or feels unstable, it may be due to a cartilage tear. This can lead to more serious injuries if ignored.
- Difficulty Moving or Loss of Motion: Struggling to fully bend or straighten a joint is a red flag. Early treatment can often prevent long-term stiffness or disability.
