Swelling After Joint Replacement: What's Normal?

Swelling is one of the most common — and most misunderstood — parts of joint replacement recovery. The good news is that swelling is completely normal. It's the body's natural response to surgery and can continue for several weeks as tissues heal.

In the early days, swelling often peaks around the knee or hip and can extend into the lower leg or ankle. This is expected and usually improves with rest, elevation and ice. Walking too far, standing for long periods or sitting without moving can all increase swelling during the first weeks.

The most effective ways to manage swelling include regular icing, elevating the leg higher than the heart and performing gentle ankle and foot exercises to stimulate circulation. Compression stockings may also be recommended.

Most patients see significant improvement in swelling by six weeks, although mild swelling can continue for several months — especially after a busy or active day. This does not mean anything is wrong.

However, new or severe swelling accompanied by redness, heat, or sudden sharp pain should be assessed promptly, as these could indicate complications.

Understanding what's normal helps you stay calm, confident and focused on recovery. Swelling is part of the process — and it gets better.
