If your knee hurts when you go up the stairs, you’re experiencing a very common symptom that can signal a few underlying knee problems. Climbing stairs places significant stress on the front of your knee, especially the kneecap (patella) and the cartilage beneath it. This pain is often a sign that something isn’t functioning optimally in your knee joint.
Common Causes of Knee Pain When Going Up Stairs
1. Patellar Malalignment
Pain in the front of the knee, often called patellar pain, is one of the most frequent reasons for discomfort while climbing stairs. The kneecap slides in a groove on the thigh bone, and if it’s out of alignment, you might feel pain, swelling, or even hear grinding sounds. This pain can be dull and achy or sharp, and it tends to worsen with activities that require bending or straightening the knee, such as stair climbing, squatting, or lunging.
2. Knee Chondromalacia (Patellar chondromalacia)
Chondromalacia patella is the softening and breakdown (early arthritis) of the cartilage under the kneecap. When this cartilage deteriorates, the knee can feel achy, swollen, or stiff, and you may notice grinding or popping sensations. Pain from chondromalacia is often worse when you climb stairs or hills, or after sitting for long periods with your knee bent. This condition can affect anyone, but it’s particularly common in women, athletes, and people who have recently increased their activity level.
3. Knee Arthritis
Osteoarthritis and other forms of arthritis can cause pain and swelling, especially during activities that put pressure on the knee, such as stair climbing. Arthritis results from thinning or damage to the cartilage that protects your bones and it can develop gradually over time or after an injury. If you notice pain, swelling, and stiffness that worsens with activity, arthritis may be the cause.
4. Patellar Tendinitis
Patellar tendinitis can be caused by running, jumping or sometimes even seemingly benign activities such as hiking. This condition involves degeneration and/or inflammation of the attachment of the patellar tendon to the patella and is often painful with jumping or stair climbing. If the pain is right under your kneecap and worse with sports this may be the problem.
What Should You Do?
If you experience knee pain when going up the stairs, try to avoid activities that aggravate your symptoms. Rest, ice, and over-the-counter anti-inflammatory medications are all easily accessible and can help you manage pain and swelling. Physical therapy is often very effective for people who have knee pain going up the stairs. Strengthening the quadriceps, hamstrings, and hip muscles are all ways you can help stabilize your knee and relieve pressure on the kneecap. Sometimes, lifestyle changes or modifications to your exercise routine are enough to manage the pain.
However, if your pain is persistent, severe, or accompanied by swelling, instability, or a history of injury, it’s important to consult an orthopaedic expert. Early diagnosis and treatment can prevent further damage and help you return to the activities you enjoy, whether that’s a walk in the park or a triathlon.
