Multivariate linear regression was used to determine HGS as a predictor of activities of daily living (ADL) and instrumental activities of daily living (IADL) in both groups: patients post hip replacement due to osteoarthritis and patients post hip replacement due to a fracture.Results: Analysis showed that pre-rehab HGS in the osteoarthritis group predicts improved activities of daily living after rehabilitation (ADL, OR = 1.098; CI 95% 1.052– 1.147 and IADL, OR = 1.182; CI 95% 1.103– 1.267) and 6 months after (ADL, OR = 1.191; CI 95% 1.066– 1.329 and IADL, OR = 1.096; CI 95% 1.012– 1.186). In the fracture group, HGS predicts the ADL (OR = 1.081; CI 95% 1.015– 1.152) after rehabilitation, and IADL after rehabilitation (OR = 1.122; CI 95% 1.046– 1.205) and 6 months after (OR = 1.090; 95% CI 1.021– 1.64).Conclusion: HGS in patients after hip replacement surgery predicts functional independence in basic and complex activities of daily living. This can allow the identification of osteoarthritis patients with low hand grip - who can be considered as patients with a higher risk of an unsatisfying outcome of surgery. These patients should undergo pre-rehabilitation and should be monitored, and/or supported in terms of rehabilitation after discharge.Keywords: hand grip strength, endoprosthesis, hip replacement, osteoarthritis, hip fracture
