Dual mobility total hip arthroplasty in osteonecrosis of femoral head: Is it suitable for Indian population?
European Journal of Molecular & Clinical Medicine,
2022, Volume 9, Issue 2, Pages 929-934
Background &Aim: Dual Mobility Total Hip Arthroplasty (DMTHA) is a reasonable
treatment option for osteonecrosis of femoral head (ONFH), especially in active young
patients who are at an increased risk of dislocation post-surgery. Moreover, lifestyle a
religious habits of Indian patients require extreme flexion and rotation, making DMTHA a
lucrative treatment option. The aim of our study is to evaluate the short-term results of
DMTHR for ONFH in the Indian population and their ability to resume their daily activities
after the surgery.
Material and Method: The study is a retrospective analysis of 23 DMTHA in 17 patients
who underwent DMTHA for ONFH between March 2018 to March 2020 and with a
minimum follow-up of one year. Patients were evaluated clinically using Harris Hip Score
(HHS) and Patient-Reported Outcome Measures (PROMs), such as the ability to squat and sit
cross-legged. Radiological evaluation was performed to detect implant migration, loosening,
periprosthetic osteolysis, or heterotrophic ossification.
Result: In our study, the mean age of patient was 36.7±9.1 years. The mean pre-operative
HHS scores of 53.8±15.4 improved to 97.0±4.2 at one year post-surgery. 94.1% patients in
our study could squat and sit cross-legged at a mean duration of 3.2 months post-surgery.
Conclusions: The use of DMTHA in Indian patients with ONFH showed good early clinical
and functional results without major complications, and simultaneously meeting their high
functional and cultural requirements
