How to Shower Safely After Knee Surgery

Navigating the first few weeks after knee surgery presents many challenges, and one of the most significant is safely managing personal hygiene. The first shower is often viewed as a major milestone in recovery, offering a return to normalcy and promoting better mental well-being. However, this task also carries a risk of injury from falls and potential surgical site infection from moisture. Success in safely showering depends entirely on meticulous preparation and strict adherence to the specific instructions provided by your surgical team. Careful planning transforms the bathroom from a hazardous area into a safe space for healing.

Clearance and Essential Preparation

The timing of your first shower is determined by your surgeon, depending on the type of incision closure and dressing used. Patients with staples, sutures, or non-waterproof dressings typically wait 10 to 14 days, until the wound is fully closed. If you are discharged with a sealed, waterproof dressing—often a transparent, flexible barrier—you may be cleared to shower as early as 48 hours post-operation. It is necessary to receive explicit clearance before the surgical site is exposed to any water.

Preparing the environment is important to prevent slips and falls, which are common in the early post-operative period. Installing temporary or permanent grab bars near the shower entrance and acquiring a shower chair or bench are mandatory safety precautions. A handheld shower nozzle is necessary, allowing you to direct the water spray away from the operated knee and wash while seated. Placing a non-slip mat both inside and immediately outside the shower area provides a stable surface for your weight-bearing foot.

Waterproofing the Surgical Site

Protecting the incision from water prevents bacterial contamination and subsequent infection. Even with a factory-applied waterproof dressing, some surgeons recommend adding an extra layer of protection for the first few showers. One effective method involves using a large, transparent, waterproof adhesive dressing that completely covers the original bandage and extends at least an inch beyond all edges.

Alternatively, you can use household plastic wrap, secured with waterproof tape above and below the knee. The goal is to create a tight seal that prevents water from migrating underneath the dressing. When showering, keep the water temperature warm, not hot, and avoid directing the pressurized spray directly onto the protected area. Once safely out of the shower, gently remove the outer waterproof layer to inspect the original dressing for signs of moisture penetration.

Techniques for Safe Entry and Exit

Transferring into the shower requires a specific sequence of movements to maintain balance and protect the operated knee. If using a walker or crutches, position your non-operated, or “good,” leg closest to the shower opening. The rule of thumb for safe transfer is “up with the good, down with the bad,” applying to both stepping up and stepping down. You should lead the movement into the shower with your non-operated leg, followed by the operated leg, using the grab bars for maximum support.

Once inside, sit immediately on the shower chair, extending your operated leg slightly forward to avoid excessive bending. Use the handheld shower nozzle to wash while seated, ensuring you do not need to twist, turn, or over-reach for soap or shampoo. When exiting, reverse the process, leading with the operated (“bad”) leg, and using safety equipment to support your body weight as you stand. This technique minimizes strain and maintains stability on the slippery surface.

Aftercare and Incision Inspection

Once dried off outside the shower, address any moisture around the surgical site. Use a clean, dry towel to gently pat the surrounding skin dry; never rub the area, as friction can irritate the incision or compromise the seal. Next, remove the outer waterproof cover (if used) and inspect the primary surgical dressing for dampness or peeling at the edges.

If the primary dressing appears dry and intact, no further action is needed until your next scheduled dressing change. If you notice moisture, seepage, or a loosening of the dressing, contact your surgeon for guidance on whether it needs immediate changing. Routinely inspect the skin around the incision for signs of complication, such as increased redness, warmth extending beyond the incision line, or thick, discolored drainage. A persistent fever above 101.5 degrees Fahrenheit also warrants an immediate call to your surgical team, as these signs may indicate a developing infection.
