Hospital disinfection protocols follow strict guidelines from the CDC and OSHA to remove bioburden and stop the spread of infections. Key cleaning, disinfection, and sterilization rules set out how hospitals must process medical instruments to keep patients safe.
Surgical instruments are classified as critical items because they enter sterile tissue and bloodstream. Critical items require sterilization, not just disinfection. Hospitals must verify exposure times, temperatures, and chemical concentrations for every sterilization cycle, and they must keep the operating room itself sterile throughout a procedure.
Surgical instruments or operating environments that aren’t properly sterilized can introduce dangerous pathogens directly into a patient’s body. The result can be severe infection, additional surgery, and life-threatening complications.
In this case, our client developed a deep infection in her new knee joint after a total knee replacement. The infection led to multiple additional surgeries, months of treatment, and permanent changes to her life that proper infection control would have prevented. The Townsley Law Firm represented her and recovered a settlement of over $550,000.
A Routine Knee Replacement Became a Deep Joint Infection
Our client came to an orthopedic surgeon with right knee pain and was diagnosed with severe varus hypertrophic arthritis. She had already had a successful replacement of her other knee. After medications, cortisone injections, bracing, physical therapy, and weight loss all failed to relieve her pain, she chose a total knee replacement.
She did everything asked of her. She followed her surgeon’s pre-operative instructions exactly, showering with antiseptic chlorhexidine wash for three days before surgery and again the morning of the procedure. The surgery went as planned, her hospital stay was uneventful, and she went home the next day.
Less than four weeks later, at her post-operative appointment, she reported increased pain, swelling, redness, and drainage from the incision. She was admitted immediately for urgent debridement surgery. Her surgeon found “gross purulence within the deep joint capsule,” and cultures taken during surgery identified Citrobacter koseri.
The day after that surgery, her surgeon documented that the hospital was investigating the source of her infection in connection with the sterility of the operating room. Our client had prepared carefully for surgery. The infection came from the environment the hospital was responsible for keeping sterile
The Hospital’s Real Failure Was Not Training Its Staff on the Change
A hospital that fails to train its staff on sterilization and fails to enforce its own policies commits an institutional failure, and that failure was the breach at the heart of this case.
Hospitals write sterilization policies for a reason. Those policies only protect patients if the hospital trains every member of its staff to follow them, verifies that they are followed, and enforces them when they are not. Sterile technique is not something staff can be expected to pick up on their own.
Here, the hospital failed to properly train its staff. It also failed to follow its own policies and procedures for maintaining a sterile environment in the operating room, and it did not enforce the sterilization process. This was less a story about one careless person and more a story about a system that did not do its job.
Infection control depends on the whole chain working, and the hospital broke the link it was responsible for. That institutional failure is what allowed an infection to reach a surgical patient who had done everything right.
How a Surgical Infection Harms a Joint Replacement Patient
A deep joint infection after a knee replacement is a serious complication that often requires additional surgery and prolonged treatment. Our client endured all of it.
When bacteria reach the deep joint capsule around a new prosthesis, they can establish an infection that the body and antibiotics alone struggle to clear, in part because bacteria can adhere to the implant. That is why her first corrective surgery required cleaning the joint down to the bone, replacing the plastic liner of the implant, and placing antibiotic beads.
That surgery was not enough. She was transferred to a specialty orthopedic hospital, where a revision surgeon replaced both components of her new knee, removed infected joint lining, placed an antibiotic delivery device, and applied a wound vacuum. Over the next seven months she needed prolonged oral and IV antibiotics through a PICC line, extended physical therapy, two knee manipulations, and a second full revision of the knee, all under general anesthesia.
The harm did not end when the infection cleared up. She lives with constant stabbing, throbbing knee pain despite prescription pain medication, and she continues physical therapy for stiffness and limited range of motion. She has great difficulty sitting, standing, or walking for long periods. She lost the supervisory job she held at the time of surgery and was forced to resign. She developed major depression and remains under psychiatric care.
Each of those consequences traces back to a hospital that did not train its staff and did not enforce the sterile procedures its patients depend on.
