The Revolutionary Breakthrough of Microprocessor Controlled Knees


 Michael Goldwin Glenolden, PA, resident, holds master's degrees in prosthetics and orthotics from Newington Certificate Program. As a certified prosthetist and orthotist for Hanger Clinic in Philadephia, Michael Goldwin Glenolden, PA, fits and designs artificial limbs for patients. Additionally, he remains interested in cutting-edge technologies, such as microprocessor control knees and feet.


MPKs, or microprocessor knees, are high-tech prosthetic knee joints that improve mobility and functionality for individuals with limb loss or difference. Equipped with sensors and microprocessors, MPK gathers data on knee movements and timing and automatically adjusts itself to provide greater flexibility and prevent falls in case of stumbles.


A critical distinction between MPKs and mechanical prosthetic knees is the operation mechanism. MPKs use computers and sensors to adapt to users' walking patterns. Conversely, mechanical knees rely on tools like hydraulics, friction, or pneumatics, which utilize fluids, surface interaction, and compressed air or gas to control movement or support artificial limbs. MPKs are especially helpful for those with bilateral leg loss, as they can adjust seamlessly, enhancing user safety.


Prospective users of MPKs should understand that these artificial knees tend to be heavier than other prosthetic knee options. Additionally, they require regular monitoring and recharging of their power source. Thus, individuals should research their options.

Addressing Metal Hypersensitivity from Prosthetics

Michael Godwin

A certified prosthetist orthotist in Glenolden, PA, Michael Godwin has served in various roles at different organizations, including as a machinist for the Army National Guard and as a CPO clinician and practice manager at Advantage O and P, for his two-decade career. He currently serves at Hanger Clinic in Philadelphia, where he fits and designs artificial limbs and braces for people. Michael Godwin of Glenolden, PA, is committed to staying current with new prosthetic technology and design.

Prostheses that are made of metals may trigger a condition called metal hypersensitivity. For this reason, doctors may recommend hypersensitivity tests for patients looking to have implants. Only 10 to 15 percent of the population is vulnerable to metal hypersensitivity. Signs and symptoms of metal hypersensitivity include swelling, pain, rashes, chronic fatigue, and chronic inflammation.

Metal hypersensitivity stems from allergic reactions to metals such as nickel, cobalt, and chromium. If you develop one or more signs and symptoms after implant surgery, you should report the symptoms to your doctor, who may order laboratory tests for metal allergy. If they find that your prosthesis is the cause of these signs and symptoms, your doctor can recommend replacing the device with a non-metal version. In situations where replacement is not feasible, oral medications and topical treatments can help manage the symptoms.
