Hydrotherapy for Hip Pain: Water Exercises for Osteoarthritis, Bursitis, and Hip Replacement Recovery
Why Hip Pain Responds Well to Water
The hip is a weight-bearing ball-and-socket joint that endures 3–5 times body weight during walking and up to 8 times body weight on stairs. When arthritis, bursitis, or surgical recovery makes the hip painful, every daily activity becomes a battle. Water reduces these forces dramatically — chest-deep immersion cuts hip loading by up to 80%.
Three water properties combine to create an ideal hip rehabilitation environment:
- Buoyancy: Reduces compressive load on the hip joint, allowing pain-free range of motion and weight-bearing exercise
- Warm water: Relaxes the powerful muscles around the hip (glutes, hip flexors, adductors) that often spasm and guard when the joint is painful
- Multi-directional resistance: Water resists movement in all directions, strengthening the hip stabilisers (gluteus medius, deep rotators) that are critical for walking, balance, and stair climbing
Condition-Specific Protocols
Hip Osteoarthritis
Clinical guidelines (OARSI, EULAR, NICE) recommend aquatic exercise as a core treatment for hip OA. A 2021 systematic review found significant improvements in pain, stiffness, and physical function with 8–12 weeks of aquatic therapy.
Focus: Maintaining hip range of motion, strengthening glutes and quads, reducing stiffness
Temperature: 33–36°C
Frequency: 3× per week, 30–40 minutes
Duration: Ongoing management (OA is chronic)
For broader arthritis-specific strategies, see our arthritis hydrotherapy guide.
Hip Bursitis (Trochanteric Bursitis)
Greater trochanteric bursitis causes pain on the outside of the hip, especially when lying on the affected side, climbing stairs, or walking. Water exercise allows hip strengthening (particularly gluteus medius, whose weakness contributes to bursitis) without the repetitive impact loading that aggravates the bursa.
Focus: Gluteus medius strengthening, iliotibial band stretching, gait correction
Temperature: 33–35°C
Caution: Avoid exercises that compress the lateral hip against hard surfaces (sideline pool wall exercises)
Total Hip Replacement (THR)
Aquatic therapy post-THR typically begins at 4–6 weeks (once the incision has fully healed). Water provides an ideal early rehab environment because patients can practise walking with near-normal gait patterns without the fall risk and joint loading of land-based walking.
Focus: Gait normalisation, hip flexion/extension range, quad and glute strengthening, balance retraining
Temperature: 33–35°C
Precautions: Follow surgeon-specific movement restrictions (anterior vs. posterior approach has different precautions regarding flexion, adduction, and rotation)
See: Our post-surgical recovery guide for general principles.
Hip Labral Tears
Whether managed conservatively or post-arthroscopy, labral tears benefit from aquatic therapy. Water allows strengthening of the hip stabilisers that support the labrum without the compressive forces and impingement positions that worsen the tear.
Focus: Deep hip rotator strengthening, core stability, controlled range of motion
Caution: Avoid deep hip flexion combined with internal rotation (impingement position) unless cleared
8 Aquatic Exercises for Hip Pain
Perform in chest-deep warm water (33–36°C).
1. Pool Walking (Forward, Backward, Sideways)
Walk in chest-deep water for 5–10 minutes. Include forward, backward, and sideways walking. Sideways walking specifically targets the gluteus medius — the most important muscle for hip stability. Focus on equal stride length with both legs.
2. Standing Hip Flexion
Hold the pool edge. Lift one knee toward the chest (as high as comfortable). Hold 3 seconds. Lower slowly. 10–15 repetitions per leg. Strengthens the hip flexors while buoyancy reduces hip joint compression.
3. Standing Hip Extension
Hold the pool edge. Extend one leg backward (keeping it straight). Hold 3 seconds. Return. 10–15 repetitions per leg. Targets the gluteus maximus — essential for walking, stair climbing, and rising from chairs.
4. Standing Hip Abduction
Hold the pool edge. Lift one leg sideways away from the body. Hold 3 seconds. Lower slowly. 10–15 repetitions per leg. This is the single most important exercise for hip bursitis, hip OA, and post-THR — strengthening the gluteus medius that controls pelvic stability during walking.
5. Standing Hip Circles
Hold the pool edge. Lift one leg slightly and make slow circles — 10 clockwise, 10 anticlockwise per leg. This mobilises the hip joint through its full range, improving synovial fluid circulation and joint flexibility.
6. Water Squats (Partial)
Stand in chest-deep water, feet shoulder-width apart. Lower into a comfortable squat (quarter to half depth depending on your hip tolerance). Rise slowly. 10–15 repetitions. Strengthens the entire lower limb chain while buoyancy reduces hip loading by 60–80%.
7. Water Lunges
In chest-deep water, take a large step forward into a lunge position. Lower gently, then push back to standing. 8–10 per leg. Builds hip-specific strength in a functional movement pattern. Buoyancy makes lunges achievable for people who can’t lunge on land.
8. Supine Flutter Kicks
Float on your back (using a pool noodle for support if needed). Perform gentle flutter kicks from the hip (not the knee). 30 seconds of kicking, 30 seconds of rest, repeat 3–4 times. Strengthens hip flexors and extensors with zero joint compression.

Home Hydrotherapy for Hip Pain
- Warm bath hip soak: Immerse the hip in warm water (37–39°C) for 15–20 minutes. While soaking, gently move the hip through its range — flexion/extension, circles, crossing the ankle over the opposite knee for external rotation stretch. Our bath therapy guide covers detailed protocols.
- Morning routine: A 5-minute warm shower directed at the hip before the first steps of the day reduces morning stiffness significantly.
- Contrast therapy: Warm water (3 min) → cold pack (1 min), repeat 3–4 cycles on the lateral hip. Effective for bursitis inflammation. See our contrast therapy guide.
Frequently Asked Questions
Is hydrotherapy good for hip pain?
Yes — aquatic therapy is recommended in clinical guidelines for hip osteoarthritis and is widely used for hip bursitis, labral tears, and post-surgical rehabilitation. Water reduces hip joint loading by up to 80%, allows pain-free exercise, and provides multi-directional resistance for strengthening the hip stabiliser muscles that protect the joint.
How soon after hip replacement can I do hydrotherapy?
Typically 4–6 weeks post-surgery, once the surgical incision has fully healed with no drainage. Some surgeons allow earlier return (3 weeks) with waterproof wound dressings. Always get specific clearance from your surgeon. Early aquatic therapy post-THR is associated with faster return to normal gait and improved range of motion compared to land-only rehabilitation.
What exercises should I do in water for hip arthritis?
The most important exercises are: pool walking (especially sideways walking for gluteus medius), standing hip abduction, hip flexion/extension, water squats, and hip circles. These maintain joint mobility and strengthen the muscles that support the arthritic hip. Start gently and progress based on pain response — if the hip aches for more than 2 hours after a session, you did too much.
Is swimming good for hip replacement recovery?
Swimming is excellent once cleared by your surgeon (typically 6–8 weeks for general swimming, earlier for water walking). Freestyle and backstroke are generally well-tolerated. Breaststroke should be introduced cautiously — the whip kick involves hip abduction and rotation that may need to be modified depending on your surgical approach (anterior vs. posterior). Always start with water walking and progress to swimming gradually.
Does warm water help hip bursitis?
Warm water (33–36°C) helps hip bursitis by relaxing the muscles around the hip (reducing compressive forces on the bursa), improving blood flow to aid healing, and enabling pain-free strengthening exercises. Contrast therapy (alternating warm and cold) may be particularly effective for reducing the chronic inflammation characteristic of bursitis.
