Does knee osteoarthritis cause difficulty walking?

Knee osteoarthritis changes how the joint moves and bears load. Discomfort may be worse when you first stand, walk uphill, use stairs, or walk for a long time. Stiffness can shorten your stride, while swelling may make the knee feel tight. These changes can cause you to shift weight onto the other leg, which may affect balance and tire the muscles around the hip and thigh.

Difficulty walking has many possible causes, so the symptom alone does not establish its cause. A clinician can consider your pain pattern, knee movement, strength, balance, previous injuries, and other health conditions.

Keep moving within a tolerable level rather than stopping all activity. Short, frequent walks on level ground may be easier than one long walk. A physiotherapist can prescribe exercises to strengthen the thigh and hip muscles, improve knee movement, and practise safer walking. Supportive footwear and a walking aid may help some people when fitted and used correctly.

Plan rests before your knee becomes very tired. If an activity clearly increases symptoms, reduce its duration or intensity and build back gradually. A healthcare professional can discuss pain-relief options that fit your medical history.

Arrange an assessment if walking difficulty is persistent, worsening, limiting work or daily activities, or causing repeated near-falls. Seek urgent care after a significant injury if you cannot put weight through the leg, the knee looks deformed, or it becomes suddenly very swollen. Urgent assessment is also appropriate with fever, marked redness or warmth, or severe pain that develops quickly.

Ask what may be limiting your walking, which exercises are suitable, whether a cane or other aid would improve safety, and how to pace stairs and longer outings. You can also ask how to tell expected activity soreness from a symptom that needs review.
