Ankle swelling four months after hip replacement

Fluid from the operated area can track down the leg, and reduced movement or altered walking can slow its return. At this stage, the pattern and trajectory matter: swelling that is gradually diminishing differs from swelling that appears suddenly or is accompanied by pain, heat or illness.

Post-operative tissue healing, muscle weakness, longer periods on your feet and changes in gait can contribute. Vein or lymphatic drainage problems, a blood clot, infection, heart or kidney conditions, and some medicines can also cause lower-leg swelling. An examination helps separate these possibilities.

Swelling related to activity may be greater later in the day and ease after elevation. A clot can present with one-sided leg swelling, calf pain, warmth or colour change. Infection around a replacement may present with increasing hip pain, wound redness or drainage, fever or feeling unwell.

Continue the walking and strengthening plan provided by your surgical or physiotherapy team, pacing activity so symptoms settle between sessions. Elevate the lower leg during rest and use comfortable ankle pumps if these are permitted. Record when swelling appears, whether it affects one or both sides, and what makes it better.

Do not restart leftover blood thinners or change prescribed medicines on your own. Before using compression, confirm that the wound is healed and that your clinician considers it suitable for your circulation and current symptoms.

Request prompt assessment for sudden or increasing one-sided swelling, a painful or tender calf, new warmth or discolouration, worsening hip pain, wound leakage, spreading redness, fever or chills. These features require evaluation for a clot or infection rather than observation at home.

Call emergency services for sudden breathing difficulty, chest pain, coughing blood, fainting or severe weakness. For swelling without red flags, contact the surgical team or primary care clinician if it is not continuing to improve, limits rehabilitation or has returned after previously settling.

Ask whether the swelling fits your expected recovery, whether your gait or activity plan needs adjustment, and whether tests for a clot or other medical cause are indicated. Confirm how to use elevation or compression and which changes should prompt contact with the surgical team.
