Why Knee Surgery Recovery Is So Hard for Women Under 60

The Paradox of the Efficient Body: Pathophysiological, Biomechanical, and Endocrinological Determinants of Compromised Knee Flexion Following Total Knee Arthroplasty in Women Under 60

Intuitively, chronologically younger patients with “efficient body mechanics” should achieve superior recovery. However, the physiological vigor defining a young, healthy female patient translates into a highly reactive immune and inflammatory response to the architectural trauma of a total joint arthroplasty. This biological efficiency acts as a catalyst for rapid soft tissue contracture. Furthermore, this demographic faces a unique convergence of physiological variables: perimenopausal endocrinological shifts, uniquely female biomechanical alignments (a wider Q angle), and a high susceptibility to amplified central sensitization to pain.
