What Is Zimmer’s Natural-Knee Durasol All-Poly Patella?
The AU-Poly (all-polyethylene) patellar components are made of machined, compression molded with ultra-high molecular weight polyethylene powder. It is intended for cemented use only. It has three grooved pegs and cement pockets on the cemented side which are designed to enhance cement fixation, and designed to provide conforming contact during normal and high flexion activities.
Of all the Zimmer components that have faced structural problems and have been recalled, the Natural-Knee Durasul All-Poly Patella was the least publicized. This device was recalled in January 2012 citing an increased risk of fracture, which could lead to complete device failure. When this recall was announced, over 100,000 devices had been implanted in patients.
What Are Complications Of Zimmer’s Natural-Knee Durasol All-Poly Patella?
According to the FDA, serious complications may be associated with any total knee joint replacement procedure. These complications include, but are not limited to:
- Loosening of the prosthetic knee components
- Dislocation and/or joint instability
- Malalignment of the prosthetic knee components
- Bone fracture
- Nerve damage
- Excessive wear secondary to damage of mating wear surfaces and/or debris that can initiate osteolysis which may result in loosening of the implant
FDA Releases Warning About All-Poly Patella
The FDA states that the patient should avoid notching, scratching, or striking the device. Improper preoperative or intraoperative implant handling or damagecan lead to crevice corrosion, fretting, fatigue fracture and/or excessive wear.
You should avoid excessive physical activities, such as impact sports (running, jogging, football, etc.) or activities that place too much stress on the knee joint (downhill skiing, mountain climbing, singles tennis, etc.). These activities significantly increase the chance of complications and/or failure of the knee components (such as breakage, excessive wear or dislocation). Your chances of success with this knee increase if you limit your activity.
Avoid trauma to your knee and weight gain as these could cause premature failure of the implant by loosening, fracture and/or wear. Loosening of the implants can result in increased production of wear particles, as well as damage to the bone making successful revision surgery more difficult.
