Summary

Reducing waste from hip and knee replacement surgeries can save money and help the environment. A study found that a significant portion of operating room waste from total hip arthroplasties (THAs) and total knee arthroplasties (TKAs) is recyclable.

Area of Science:

Orthopedic Surgery
Environmental Science
Waste Management

Background:

Total hip arthroplasties (THAs) and total knee arthroplasties (TKAs) generate substantial operating room waste.
Current waste processing is costly and has environmental implications.
Opportunities exist to reduce waste and improve sustainability in orthopedic procedures.

Purpose of the Study:

To quantify the amount and types of waste generated during primary THAs and TKAs.
To identify potentially recyclable materials within the surgical waste stream.
To inform the development of more effective waste management strategies in orthopedic surgery.

Main Methods:

Prospective identification of 20 consecutive patients undergoing primary THA or TKA.

Waste (excluding liquids) was collected and sorted during each procedure.

Waste composition was analyzed to determine the proportion of recyclable materials.

Main Results:

Average waste per THA was 30.0 lb; per TKA was 33.2 lb.
Approximately 22.8% of THA waste and 22.0% of TKA waste was potentially recyclable paper or plastic.
Significant volumes of clean, recyclable materials are discarded as contaminated waste.

Conclusions:

Implementing targeted recycling programs for clean operating room waste can reduce disposal costs.
Orthopedic surgery waste management can be optimized by focusing on recycling initiatives.
Reducing contaminated waste processing is key to decreasing hospital overhead and environmental impact.
