Proximal femoral fractures are associated with increased mortality in older adults and may contribute to loss of functional independence, resulting in a higher risk of long-term institutionalization. The SIOT 2021 guidelines emphasize that management of older patients with proximal femoral fracture (FPF) requires a multidisciplinary approach, ideally integrated across all phases of care, including rehabilitation and secondary prevention at the community level, according to a continuity-of-care model that incorporates the implementation of Fracture Liaison Services.

Multiple clinical, social, and environmental factors influence fall risk. Falls are also associated with psychological consequences. Age-related reductions in muscle strength contribute to progressive functional decline, increased morbidity and mortality related to falls, reduced quality of life, depression, and hospitalization.

Sarcopenia is characterized by both quantitative and qualitative reductions in muscle tissue, including progressive replacement of contractile tissue with fibrous and adipose tissue. The European Working Group on Sarcopenia in Older People (EWGSOP), in its updated consensus (EWGSOP2), identifies low muscle strength as the primary parameter of sarcopenia, accompanied by a significant and generalized reduction in muscle mass.

A use-case model dedicated to patients with sarcopenia describes typical demographic and social characteristics, associated comorbidities, and specific care needs, with the aim of identifying the most appropriate management pathways.

This study adopts a person-centered approach to design, validate, and implement an integrated strategy for fall prevention, taking into account the multiple determinants of fall risk and related adverse health outcomes.

Inclusion Criteria

Age ≥ 65 years at the time of enrollment

Radiographically confirmed knee osteoarthritis or hip osteoarthritis classified as Kellgren-Lawrence grade 2 or 3

Clinical indication for structured rehabilitation therapy

Diagnosis of sarcopenia according to European Working Group on Sarcopenia in Older People 2 (EWGSOP2) criteria, defined as:

Low muscle strength (handgrip strength < 27 kg in men or < 16 kg in women, or chair stand test > 15 seconds for 5 rises), and

Reduced muscle mass confirmed by a validated assessment method (e.g., dual-energy X-ray absorptiometry [DXA] or bioelectrical impedance analysis [BIA]) according to established cut-off values

Exclusion Criteria

Absolute contraindication to rehabilitation therapy as determined by the treating physician

Hemodynamic instability, including uncontrolled arrhythmias, symptomatic hypotension, or acute coronary syndrome within the previous 3 months

Unstable fractures

Severe open wounds or lacerated-contused injuries requiring surgical management

Severe cognitive impairment preventing participation in rehabilitation activities (e.g., Mini-Mental State Examination score < 18)

elderly>65 years with higher fall risk
