Getting Back in the Water: Total Hip and Knee Replacements and Water Sports

Total hip and knee replacements (arthroplasty) have transformed life for millions dealing with severe arthritis, injury-related damage, or chronic joint pain. Modern implants and surgical techniques allow many patients to return to an active lifestyle, including low-impact water sports that were once painful or impossible. Swimming, water aerobics, kayaking, paddleboarding, and even cautious scuba diving or surfing can become realistic goals again—often with less stress on the new joint than land-based activities.

Why Water Sports Are Often Ideal After Joint Replacement

Water’s natural properties make it one of the most joint-friendly environments for recovery and long-term activity:

•  Buoyancy reduces body weight on the hip or knee by up to 90% (depending on water depth), easing pain and allowing earlier movement.

•  Hydrostatic pressure helps decrease swelling and improves circulation.

•  Water resistance provides gentle strengthening without the pounding of running or jumping.

Studies and orthopedic guidelines consistently rank swimming and aquatic exercises among the safest and most beneficial activities post-surgery. Low-impact water pursuits help maintain cardiovascular fitness, rebuild muscle (especially around the replaced joint), improve range of motion, and boost overall well-being without accelerating implant wear as much as high-impact sports.

Many patients report returning to or even starting water-based hobbies after replacement. Patient surveys show high satisfaction with activities like swimming and cycling, which often see increased participation post-surgery compared to pre-op levels for some individuals.

Typical Recovery Timeline for Returning to Water

Recovery varies by individual factors like age, overall health, pre-surgery fitness, and whether it’s a hip or knee replacement. Knee recovery generally takes a bit longer (6–10 weeks for basic mobility vs. 4–6 weeks for hip).

•  Early phase (incision healing): Most surgeons recommend waiting until the surgical wound is fully healed and closed—typically 4–6 weeks—before submerging in a pool, ocean, or other water. This minimizes infection risk. Some allow showering earlier with precautions, but full submersion usually requires clearance.

•  Aquatic therapy/rehab start: Once cleared (often around 4–6 weeks), many begin supervised or gentle pool exercises. This can include water walking, light kicking, or range-of-motion work. Aquatic physical therapy often leads to faster functional gains, reduced pain/swelling, and better strength (e.g., hip abductors) compared to land-only PT in the early stages.

•  Swimming and basic water activities: Generally safe once the incision heals. Start with gentle laps using a pull buoy or limited kicking, open turns (avoid flip turns initially for knee patients), and avoid breaststroke for the first 2–3 months until coordination and range of motion improve.

•  More dynamic water sports (kayaking, paddleboarding, light surfing): Often possible by 3–6 months for low-to-moderate intensity, assuming good progress in PT and surgeon approval. Full confidence may take up to a year.

•  Scuba diving: Feasible for many after clearance, but start gradually in controlled environments (pool to open water). Consider dive medicine consultation for decompression risks and joint loading.

By 6 months, a large percentage of patients (often 70–80%+ in studies) return to pre-surgery recreational activities, with low-impact options like swimming showing strong retention or increases.

Recommended Water Sports and Modifications

Highly recommended (low-impact):

•  Swimming and water aerobics

•  Water walking/jogging

•  Pool-based cycling motions or flutter kicks

•  Gentle kayaking or canoeing (once strength and balance return)

Moderate caution:

•  Stand-up paddleboarding or recreational surfing (focus on balance and avoid big waves initially)

•  Light scuba or snorkeling

Generally avoid or approach with high caution:

•  High-impact or contact elements (e.g., aggressive water polo, cliff jumping). These increase risks of dislocation, implant loosening, or fracture over time.

For hip replacements, avoid extreme positions that could risk dislocation early on. For knees, focus on controlled movements to protect range of motion. Always prioritize proper technique and listen to your body—stop if you feel sharp pain.

Local Expertise: Dr. Dustin Hambright and Returning to Water Sports

In the Charleston, South Carolina area, many patients turn to fellowship-trained hip and knee replacement specialist Dr. Dustin Hambright (of South Carolina Sports Medicine & Orthopaedic Center and affiliated with Novant Health and Trident Health) for their procedures. Dr. Hambright emphasizes advanced techniques—including robotic-assisted and minimally invasive approaches—to help patients recover faster and get back to the activities they love. He frequently addresses questions about post-op water activities, noting that once the incision is fully healed (typically 4–6 weeks), aquatic therapy and swimming can play a key role in building strength, mobility, and confidence with minimal joint stress. His patients often share stories of returning to pool exercises, kayaking in local waterways, or enjoying Lowcountry beaches and lakes pain-free after surgery, thanks to personalized recovery plans that incorporate water-based rehab when appropriate.

Important Precautions and Tips

•  Always consult your surgeon and physical therapist before returning to any water activity. Individual factors (implant type, surgical approach, bone quality) matter.

•  Start slow: Begin in shallow or chest-deep water, progress gradually, and incorporate PT-recommended exercises (e.g., water squats, hip curls, underwater walking).

•  Warm water (around 92–95°F for therapy) can relax muscles and ease stiffness.

•  Use aids like noodles, fins (cautiously), or kickboards as needed.

•  Monitor for swelling, instability, or unusual pain—report it promptly.

•  Maintain a healthy weight and continue strengthening exercises on land as well for balanced recovery.

•  Pre-surgery (“prehab”) aquatic therapy can make post-op recovery smoother by building strength and familiarity with water movement.

Joint replacements aren’t a fountain of youth, but they often restore the ability to enjoy life again—including refreshing days on the water. Many patients say activities like swimming or kayaking feel liberating after years of pain-limited mobility.

If you’re preparing for or recovering from hip or knee replacement and love water sports, discuss your goals early with your doctor—many active patients successfully return to the pool, lake, or ocean and never look back. Stay consistent with rehab, be patient, and enjoy the journey back to movement!
