defenition/description[edit | edit source]

In people with a flexion deformity one of them or both are reduced. It develops as a result of failure of knee flexors to lengthen in tandem with the bone, especially when there is inadequate physical therapy to provide active and passive mobilization of the affected joint.Cite error: Invalid <ref> tag; name cannot be a simple integer.
