Activities and Sports After a Knee Replacement: What You Can Safely Do
Key takeaways
- Low-impact activities such as walking, cycling, swimming, and golf are encouraged after a knee replacement and help the implant last.
- High-impact, twisting sports like running, singles tennis, and football are usually discouraged because they wear the implant faster.
- Most people return to normal activities within about 3 months, with full recovery and confidence taking 6 to 12 months.
- Around 90 to 95% of knee replacements are still working at 10 years, and sensible activity choices help protect that.
- Always get the timing for your specific sport cleared by your own surgeon and physiotherapist before you start.

Low-impact activities such as walking, cycling, swimming, and golf are encouraged after a knee replacement, while high-impact, twisting sports like running and football are usually discouraged because they wear the implant faster. The aim is to stay active in ways that protect the joint, because sensible activity choices help your replacement last. Around 90 to 95% of knee replacements are still working at 10 years1, and most people return to normal activities within about 3 months2.
I was anxious that a new knee meant the end of doing things I enjoyed. It turned out to be the opposite, with one honest caveat: I had to trade the high-impact activities for low-impact ones. This guide, checked by a consultant orthopaedic surgeon, sets out which activities are encouraged, which to approach with care, and when you can return to each. For the bigger picture, start with our guide to knee replacement surgery.
Which activities are encouraged?
Low-impact activities that load the knee smoothly, without pounding or sharp twisting, are actively encouraged. They build the muscles that support the implant and keep the joint moving without accelerating wear. The American Academy of Orthopaedic Surgeons lists walking, swimming, cycling, golf, and dancing among the recommended options3.
Good choices include:
- Walking: the simplest and best. You will use walking aids for 2 to 6 weeks4, then build distance steadily.
- Swimming and water aerobics: the water takes the load off the joint.
- Cycling: a stationary bike early on, then gentle road or path cycling.
- Golf, bowls, and doubles tennis: low-impact and sociable.
- Dancing and gentle hiking: fine once strength and balance return.
The day I walked a full mile without a stick felt like a bigger milestone than leaving hospital had.
Which sports should you approach with care or avoid?
High-impact and twisting sports are usually discouraged because the repeated loading and rotation wear and loosen the implant sooner. A knee replacement is metal and plastic resurfacing all three compartments of the knee, and the plastic bearing wears faster under pounding. Versus Arthritis advises sticking to low-impact activity and avoiding high-impact sport to protect the joint5.
Sports usually discouraged or approached only with your surgeon’s agreement:
- Running and jogging: the repeated impact is the main concern.
- Singles tennis, squash, and badminton at pace: sharp stops and twists.
- Football, rugby, and basketball: contact plus twisting.
- Skiing on hard runs and downhill mountain biking: high impact and fall risk.
The honest reality is that about 1 in 5 people feel the knee is never quite normal2, and high-demand sport is more likely to expose that. If a sport matters deeply to you, ask your surgeon about your specific case rather than assuming.
When can you return to each activity?
Most low-impact activity can resume within the first weeks to 3 months, while higher-demand sport comes later, once strength and control return over 6 to 12 months. Recovery is individual, so these are typical guides rather than fixed dates, and your physiotherapist should clear each step.
| Activity | Typical earliest return |
|---|---|
| Walking with aids | From day of or day after surgery |
| Stationary cycling, swimming | Within the first few weeks |
| Golf (putting, then full swing) | Around 3 months |
| Driving | Usually around 6 weeks |
| Hiking, doubles tennis | Around 3 to 6 months |
Full recovery, with swelling settled and strength and confidence back, takes 6 to 12 months and sometimes longer2. For the week-by-week experience, see our knee replacement recovery timeline, and for the strength work that makes return to sport safe, our knee replacement exercises.
How activity choices affect how long the knee lasts
Choosing low-impact activity helps the implant reach its expected lifespan of 15 to 20 or more years. Registry data shows around 90 to 95% of knee replacements are still in place at 10 years1. High-impact loading is one of the factors that wears the plastic bearing and can shorten that, which is the main reason younger and more active patients are counselled carefully.

Common questions
Can you run after a knee replacement?
Running is generally discouraged after a knee replacement because the repeated high impact wears the implant faster and can loosen it over time. Most surgeons advise low-impact alternatives such as brisk walking, cycling, or using a cross-trainer instead. A small number of fit patients run with their surgeon's agreement, but it is not the standard advice. Around 90 to 95% of knee replacements are still in place at 10 years, and avoiding high-impact loading helps protect that.
When can I play golf after a knee replacement?
Many people return to golf around 3 months after surgery, often starting with putting and chipping before a full swing. Golf is one of the encouraged low-impact activities. Use a buggy at first rather than walking the full course, and let your surgeon and physiotherapist confirm you are ready, as recovery varies and full strength can take 6 to 12 months.
What sports should you avoid after a knee replacement?
High-impact and twisting sports are usually discouraged: running, singles tennis, squash, football, basketball, skiing on hard runs, and contact sports. These load and twist the implant, which can wear or loosen it sooner. Low-impact swaps such as swimming, cycling, doubles tennis, and golf give similar enjoyment with far less risk to the joint.
Can I kneel and garden after a knee replacement?
Kneeling is safe for the implant but is often uncomfortable, and about 1 in 5 people find the knee never feels completely normal, with kneeling a common difficulty. Gardening is fine once you are healed; use a kneeling pad or a long-handled tool, and rise through your stronger leg. Build up gradually rather than spending a whole day on your knees at first.
How long until I can return to normal activities?
Most people return to most normal activities within about 3 months, while full recovery, with swelling settled and strength and confidence back, takes 6 to 12 months and sometimes longer. Low-impact exercise can usually start within the first weeks under physiotherapy guidance; higher-demand sport comes later once strength and control return.
Is walking good after a knee replacement?
Yes. Walking is one of the best activities after a knee replacement: it is low-impact, builds the muscles that support the joint, and helps reduce stiffness and swelling. You will start with walking aids for 2 to 6 weeks, then build distance gradually. Most people walk comfortably without aids within several weeks, then keep increasing their range as confidence returns.
