This review summarises the current evidence on returning to sport after knee replacement, including both total knee replacement (TKR) and partial knee replacement (UKR).

Key points

  • Most patients can return to sport after knee replacement
  • Low-impact activities are safe and recommended
  • Return to sport usually begins between 3 and 6 months
  • Partial knee replacement (UKR) has higher return-to-sport rates than total knee replacement (TKR)
  • High-impact sports are generally discouraged
  • Recovery and return depend on patient factors such as age, fitness, and motivation

Why is this important?

Many patients considering knee replacement want to know whether they can stay active afterwards.

Traditionally, surgeons advised avoiding sport. However, more recent evidence suggests that returning to activity is not only possible, but beneficial for overall health and quality of life.

What does recovery look like?

Recovery follows a gradual progression:

  • First 3 months: focus on regaining movement, strength, and balance
  • 3 to 6 months: return to light sporting activity
  • Beyond 6 months: progression to more demanding activities depending on confidence and function

Return to sport should always be gradual and guided by your surgeon and physiotherapist.

Total vs partial knee replacement

Partial knee replacement (UKR)

  • Higher return-to-sport rates, up to around 75% to 100%
  • Faster recovery, often by around 3 months
  • Better functional performance in sport

Total knee replacement (TKR)

  • Return-to-sport rates vary widely, around 36% to 89%
  • Slightly slower recovery
  • Excellent outcomes for pain relief and daily function

Which sports are recommended?

Sports are generally grouped into three categories:

Recommended (low impact)

  • Walking
  • Cycling
  • Swimming
  • Golf

These are encouraged for all patients.

Allowed with experience (moderate impact)

  • Hiking
  • Skiing
  • Doubles tennis
  • Gym-based exercise

These may be appropriate if you have previous experience and good control.

Generally discouraged (high impact)

  • Running
  • Football
  • Basketball
  • Singles tennis

These place higher stress on the implant and may increase the risk of wear over time.

What affects your return to sport?

Several factors influence recovery:

  • Age: younger patients often return more easily
  • Pre-injury activity level: active patients are more likely to return
  • Motivation: a key driver of recovery
  • Weight: higher body weight may affect outcomes
  • Rehabilitation: structured physiotherapy is essential

What does this mean for you?

Most patients can return to an active lifestyle after knee replacement.

Key things to understand:

  • Activity is encouraged and beneficial for overall health
  • Low-impact sport is safe and recommended
  • Higher-impact sport may be possible in selected cases, but should be approached with caution

The goal of knee replacement is not just pain relief, but helping you return to an active and enjoyable lifestyle.

Key considerations

  • Return to sport typically starts at 3 to 6 months
  • Full recovery continues beyond this
  • Activity should be built up gradually
  • Treatment and advice should be tailored to your goals and lifestyle
