Plain English Summary

Background and study aims
Hip fractures are breaks or cracks at the top of the thigh bone (femur) next to the hip joint. They often happen due to a fall, particularly in the elderly as they may fall more often due to medical conditions, poor eyesight or mobility issues. Hip fractures need to be treated by surgery and the affected bone is typically replaced by an artificial hip (arthroplasty). Afterwards, physiotherapy plays a very important part of a patients recovery, helping them to regain their mobility and independence. The physiotherapy program includes exercises that activate muscle groups around the hip and knee joints in order to maximize strength and flexibility of the limb. How well the hip abductors (the muscles that lift the thigh out to the side) work is vital for the proper functioning of the hip joint, as well as overall functional ability of the patient. Here, we want to find out whether and how strengthening of the hip abductor muscles helps patients to recover from a partial hip replacement (hemiarthroplasty) after a hip fracture.

Who can participate?
Adults aged 70–85 undergoing hemiarthroplasty after a hip fracture in the 1st Orthopaedic Department of the “KAT” General Hospital of Attica, Greece.

What does the study involve?
Participants are allocated into one of two groups. Those in group 1 (control group) follow the classical physiotherapeutic protocol. Those in group 2 (research group) follow a modified physiotherapeutic protocol with a focus on strengthening hip abductor muscles. Hip abductor muscle strength and overall functional ability are assessed at 3 months and again at 6 months after surgery.

What are the possible benefits and risks of participating?
Participants are treated by a standardized physiotherapy protocol regardless the modifications to be performed. Given the study’s hypothesis, all patients follow a better or equivalent to the classical rehabilitation program. Information obtained from this study may benefit patients undergoing hemiarthroplasty after a hip fracture in the future. Participation in this study does not increase the likelihood of possible complications after surgery.

Where is the study run from?
1. Laboratory for Research of the Musculoskeletal System (LRMS) of the Faculty of Medicine, School of Health Sciences, National and Kapodistrian University of Athens (Greece)
2. 1st Orthopaedic Department of the “KAT” General Hospital of Attica (Greece)

Study information

Scientific title

The effect of modified physiotherapy intervention in postoperative abductors muscles efficiency and functional ability of hip-fractured patients.


Study hypothesis

The proposed modified physiotherapy intervention may contribute to faster and level best functional recovery compared with the classical postoperative physiotherapy protocol.

Drug names

Primary outcome measure

Difference in postoperative functional status according to strengthening of hip abductor muscles. This is measured 60 days (3 months) after surgery in Newton (N) with a reliable electronic dynamometer.

Secondary outcome measures

1. At the day of hospital admission evaluation of the prefracture functional status using self-reported measure.
2. Evaluation of postoperative hip abductor muscles strength and functional status using both self-reported (using a questionnaire) and physical performance (Timed Up & Go Test) measures and an objective measure of abductors muscles strength using an electronic dynamometer(3rd and 6th month after surgery)
