What Should I Be Doing 2 Weeks After Knee Replacement?

Two weeks after a total knee replacement is still early recovery. You may be more independent than you were in the first few days, but swelling, stiffness, disturbed sleep and the need for a walking aid can all still be completely normal.
The goal at two weeks is not to prove how much you can do. It is to build a reliable daily routine that improves movement, walking and strength without repeatedly overwhelming the knee.
What is typical at the two-week stage?
By around two weeks, pain at rest is often improving and swelling may be beginning to plateau or slowly reduce. The knee can still feel warm, heavy or tight, particularly later in the day.
Many people are moving around the house more independently and may be starting short outdoor walks. Some are beginning to reduce from two crutches to one, but others still need both. Neither is automatically a problem.
How much should you be walking?
There is no single correct distance. The better question is whether walking is becoming more confident and controlled.
Short, regular walks are generally preferable to one ambitious walk that causes a major increase in swelling afterwards. Build duration gradually and keep the walking aid you need to maintain a good pattern.
Should you still be using crutches?
Possibly. Around week two, many patients start discussing progression from two crutches to one. The decision should depend on strength, balance and gait quality rather than simply reaching day 14.
If removing a crutch causes a clear limp, shorter steps or loss of confidence, it may be too soon to remove that support.
What range of movement should you have?
The handbook uses approximately 100-110 degrees of active knee bend with full extension as a broad aim by the end of week two. These are not pass-or-fail numbers.
Swelling, pain and pre-operative stiffness all affect range. The important pattern is that movement is gradually improving rather than the knee becoming progressively stiffer.

Which exercises become important now?
Early activation work still matters, but week two is also when functional strengthening begins to become more prominent. Exercises may include sit-to-stands, mini squats, standing calf raises, standing hip abduction and standing hip extension, alongside knee mobility work.
Quality matters more than forcing repetitions. Sharp joint pain is different from normal muscular effort.
Should you still use ice and elevation?
Yes, if they are helping. The guide recommends using ice for around 15-20 minutes after exercise or increased activity as needed, with a cloth between the skin and cold pack. Elevation can remain particularly useful in the evening when swelling has accumulated through the day.
Avoid routinely resting with a pillow directly underneath the knee, because keeping the knee in a bent position for long periods can work against restoring extension.
What everyday activities are reasonable?
Light household tasks may begin as comfort allows. The emphasis should still be on pacing rather than trying to return immediately to your normal workload.
If you spend an hour doing housework and the knee becomes dramatically more painful or swollen for the rest of the day, that was probably too much for your current capacity.
What should you not worry about at two weeks?
A degree of swelling, warmth, bruising, stiffness and disrupted sleep can still be normal. Progress often looks uneven from day to day.
Judge recovery over several days rather than by one difficult afternoon.
What should make you contact your team?
A wound that is not closing, increasing rather than reducing swelling, worsening redness or discharge, rapidly increasing pain, fever, or a gait that remains very unsteady despite your aid should be discussed with the appropriate healthcare team.
When should you seek further advice?
Recovery is rarely a perfectly straight line, but new or rapidly worsening symptoms should not simply be pushed through. Contact your surgical team, GP or physiotherapist if pain, swelling, movement or function is moving in the wrong direction rather than gradually improving. Seek urgent medical attention for symptoms such as sudden breathlessness or chest pain, marked one-sided calf swelling, a hot increasingly red joint with fever, sudden loss of function, or other symptoms your surgical team has told you require urgent review.
