about us

Aging is Moving...Forward™

More than 1 in 2 adults in the US report joint problems. Health systems are tackling this volume of patients by accelerating outpatient procedures and same day discharge of patients to their home. Clinicians need visibility into patients at home. Patients need help to adhere to their care plan at home. This is the problem Plethy is solving.

Joint health leads to a better quality of life and the ability to perform normal activities of daily living (ADL) – at home, at work, or at leisure. Joint health is also critical for managing chronic conditions.

As we all grow older and live longer, the costs of joint care will only increase, further adding to the burden on society. Joint health gives us independence to follow all the paths life may take us, or to forge our own path.

Plethy is a digital health solutions company based in Silicon Valley focused on delivering joint care at home. Our mission is to improve outcomes and reduce costs through increased patient engagement.

Fun Fact

The word Plethy comes from an ancient Indo-European word that gave us plethora and plenty — denoting abundance. In medicine, plethysmograph is key to measuring volume changes (“fullness”) from circulation.

We at Plethy aspire for an abundance of health and good Qi (“circulation”) for everyone.
