Most people can get into a pool within a few weeks of rotator cuff surgery, but only to walk and move gently in the water. Actual swimming comes much later, usually from about 4 months, and only once your surgeon clears it.
The wounds come first. Don’t get in until they’re fully closed and dry, with no scabs or gaps, and your surgeon has said so. That’s rarely before 2 to 3 weeks.
The strokes come back in a set order:
- Kicking only, from about 10 to 12 weeks
- Breaststroke, from about 4 months
- Freestyle and backstroke, from about 4 to 5 months
- Butterfly LAST, from about 5 to 6 months or later
Your surgeon’s protocol comes first. A large tear or a repair in weaker tissue often means waiting longer at every step. For the overall timeline, see rotator cuff surgery recovery week by week.
When can I get in the pool?
- Not until the wounds have healed: soaking an open wound raises the risk of infection. The MedlinePlus shoulder surgery discharge advice is clear: no bath, hot tub or pool until your surgeon says it’s OK
- Showers are different: you can usually shower sooner with the wounds covered. Ask what your team prefers
- Hot tubs wait longer: they’re warm, shared and harder to keep clean. Check with your surgeon even after you’re allowed in a pool
The first weeks in the water
Some rehab programs use the pool from as early as 2 to 6 weeks after surgery, once the wounds have closed. Water takes the weight of the arm, so gentle movement can feel easier than on land. This is exercise in water, not swimming.
- Walking in water: chest-deep walking forward, backward and sideways is good for general fitness while the shoulder heals. Let the operated arm rest by your side
- Gentle arm movement: only the movements your physio has given you, at the range your surgeon allows. The rules on land still apply in the pool
- Leg work: hold the side with your good arm and kick, or do knee lifts and squats in the water
- Getting in and out: use the steps or a ramp. Don’t push up on the edge or haul yourself up a ladder with the operated arm. Wet floors are slippery, and a fall onto that arm is the last thing you need
Which stroke first, and why
The order follows how far each stroke takes your arm overhead and how much force it asks of the repaired tendon.
- Kicking (about 10 to 12 weeks): legs only. Kick on your back with your arms by your sides, or hold a float against your chest. Don’t stretch both arms out in front on a kickboard until you’re allowed to lift the arm that high
- Breaststroke (about 16 to 18 weeks): usually first because the arms stay under the water and in front of you, with no overhead reach. Keep the pull short and narrow
- Freestyle (about 18 to 22 weeks): the arm goes overhead and turns inward on every stroke, which works the cuff hard. Start with a few lengths, not a full session
- Backstroke (about 18 to 22 weeks): the arm reaches right back behind your head, a position that stretches the front of the shoulder. After a repair, it comes back less often than freestyle or breaststroke
- Butterfly (about 22 to 26 weeks or later): both arms overhead at once, with no body roll to share the load. It’s the most demanding stroke on the shoulder
Walking in the pool comes in weeks. Swimming comes in months. Butterfly comes last.
How to change your stroke
- Shorten the reach: don’t stretch the arm as far forward or as far back as you used to. Full reach comes last
- Roll your body in freestyle: rotating from the hips takes strain off the shoulder. A flat, arms-only stroke loads the cuff more
- Breathe to both sides if you can. Always breathing to one side makes one shoulder do extra work
- Keep your hands in front of your shoulders in breaststroke, and don’t sweep wide
- Enter the water just outside your head in backstroke, not directly behind it
- Fins help, paddles don’t: fins let your legs do more of the work. Hand paddles and pull buoys load the shoulder, so leave them until you’re back to full strength
- Mix strokes and rest: short sets with rests beat long continuous lengths of one stroke
How long until I’m back to normal swimming?
Longer than most swimmers expect.
In one group of middle-aged and older swimmers, almost everyone got back in the water, typically around 8 months after surgery. But only about half got back to their full previous level, and that took about a YEAR. Freestyle came back for nearly all of them. Butterfly came back for fewer than half.
The people who did best had good lifting movement back first. Your land exercises are what get you back in the pool. See exercises after rotator cuff surgery.
How pain should behave
- During the swim: a mild ache or tiredness in the shoulder is normal
- Afterwards: it should settle within about 30 minutes. If it doesn’t, swim less next time
- The next morning: you should feel no worse than before the swim. If you do, drop back a step
- Pinching at the top of the stroke: shorten the reach or go back to breaststroke for a while
- Stiffness getting worse rather than better with swimming is worth mentioning to your physio. See stiff shoulder after surgery
Call your surgeon today if
- A wound becomes red, hot, swollen or starts leaking after you’ve been in the water
- You feel unwell or feverish
- You felt a pop during a stroke and suddenly can’t lift the arm, though someone else can still lift it for you
- You have new numbness or weakness in the arm
Go to the emergency department if
- You have chest pain, sudden breathlessness or cough up blood
Mention it at your next appointment if
- Pain after swimming lasts into the next day, again and again
- One stroke still pinches after several weeks of easing back
- You’re unsure which strokes you’re allowed yet
Getting in the pool is about the wound. Getting back to swimming is about the tendon.
