How effective is physiotherapy for knee osteoarthritis?

Knee osteoarthritis can cause pain, stiffness and reduced confidence with stairs, walking or standing. Physiotherapy does not reverse joint changes, but it can improve how the joint is supported and used. A plan may include quadriceps and hip strengthening, range-of-motion exercises, balance practice, pacing and advice about walking aids or activity choices. The right amount of challenge matters: some temporary muscle tiredness is expected, while a lasting increase in joint pain or swelling means the load needs review.

Begin with exercises that fit your current ability and practise them regularly. Break demanding tasks into manageable periods, vary sitting and walking, and choose lower-impact activities when the knee is irritable. Keep a simple record of stiffness, walking tolerance and recovery after exercise. A physiotherapist can progress resistance, balance and functional practice as control improves. Weight, footwear, medication and other health conditions may also be relevant to the overall plan.

Seek prompt care for a hot, red knee with fever, a sudden major swelling, a new deformity or an inability to bear weight. Arrange review when pain changes suddenly, the knee repeatedly gives way or locks, or symptoms keep limiting sleep and basic activities. These signs deserve assessment rather than being assumed to be ordinary osteoarthritis symptoms.

Which exercises suit my current knee symptoms? How should I respond if pain rises after exercise? Would a walking aid, brace or change in activity help, and what other treatments should be considered alongside physiotherapy?
