Bio-synthetic Union for Long Term Stifle Stability
Immune Mediated Prostheses Encasement Provides Fortification and Durability of the Repair
Like all extracapsular surgical procedures, NAHAH’s MFLS surgical services benefit from the immune system’s reaction to the implanted prostheses referred to as Foreign Body Reaction (FBR) that strengthens and fortifies the repair. In time, immune-mediated encasement of the implanted nylon prostheses forms a bio-synthetic union. Ultimately, the body’s own tissues will provide a substantial portion of the surgical repair’s strength and structural integrity. Utilizing implant materials that have a high combined material strength and allowing for a high factor of safety provides the early strength of the surgical repair. With healing and time, the bio-synthetic union encasing the implanted materials gets stronger and provides fortification for the long-term strength and durability of the surgical repair.
NAHAH’s MFLS surgical services stabilize and reinforce the original anatomy of the stifle and the immune system’s response to implanted materials incrementally encases the implanted synthetic prostheses in scar tissue (collagen) fortifying the repair by forming a bio-synthetic union over time. The surgery essentially amounts to surgically implanting two nylon prostheses (each comprised of multiple nylon filaments) that form the framework or scaffolding on which the body gradually builds a new “collagen ligament” that grows stronger with healing over time.
Cadaver studies (studies on deceased patients having previously had nylon implants) have demonstrated this immune-mediated encasement and fortification of surgically implanted nylon prostheses. When pathologists looked under a microscope, they saw that these nylon implants had become encased in scar tissue over time. Similarly, if a patient has an embedded foreign body (such as a splinter), the immune system attempts to isolate the foreign body by walling it off with scar tissue In NAHAH’s MFLS surgical services, the two implanted nylon prostheses provoke an immune-mediated encasement of the prostheses (encasement in scar tissue), which incrementally proliferates and grows stronger with time. Scar tissue is made of collagen, as are ligaments and tendons made of collagen (they are slightly different forms of collagen). Ultimately, the structural integrity of the surgical repair benefits from this immune-mediated encasement and fortification during the healing process, and the surgical repair grows stronger over the months following surgery forming this bio-synthetic union.
