The difficulty in eradicating established biofilms often necessitates complete suture removal, which can be invasive and disruptive to the healing process.

Suture knot security is another area of concern, especially in dynamic tissue environments. Over time, the knots in polypropylene sutures may loosen or slip, compromising wound closure. This is particularly problematic in areas subject to constant movement or tension, such as in orthopedic or cardiovascular applications.

The interaction between polypropylene sutures and surrounding tissues over extended periods can lead to tissue erosion or suture extrusion. This is especially challenging in delicate tissues or in areas where the suture is close to the skin surface. Such complications can necessitate additional medical interventions and negatively impact patient comfort and satisfaction.

Environmental factors, such as exposure to UV radiation or certain chemicals used in medical settings, can potentially accelerate the degradation of polypropylene sutures. This poses challenges in maintaining suture integrity in various clinical scenarios, particularly in long-term implantation or in exposed wound closures.

Lastly, the difficulty in accurately predicting the long-term behavior of polypropylene sutures in diverse physiological environments remains a significant challenge. Individual patient factors, such as metabolism, immune response, and tissue characteristics, can greatly influence suture longevity, making standardized predictions and recommendations challenging for healthcare providers.

The exploration of polypropylene suture material longevity in healthcare is currently in a mature stage of industry development, with a significant market size due to its widespread use in medical procedures. The global suture market, including polypropylene materials, is estimated to be worth billions of dollars.
