Overview
Brief Summary
Rationale of the study is to evaluate through a prospective randomized controlled study if a modified direct superior posterolateral approach (sperimental approach) to the hip articulation which entirely spares i.e. avoids the sacrifice of the fascia lata might elicit a better outcome in terms of gait, balance, strengths recovery, clinical performance, patient reported outcome measurement (Short Form-12(SF-12); Hip disability and Osteoarthritis Outcome Score (HOOS)) and overall recovery time in patients undergoing TotalHipArthroplasty with the aid of dedicated, modified instrumentation in order to properly access this modified route.
The investigators expect an improvement on selected gait analysis parameters in sperimental approach in order of 2% of range of motion (ROM) recorded 1 month after surgery. Based on this assumption sample size calculation will be conducted.
Detailed Description
Rationale of the study is to evaluate through a prospective randomized controlled study if a modified direct superior approach (experimental approach) to the hip articulation which entirely spares i.e. avoids the sacrifice of the fascia lata (posterolateral approach) might elicit a better outcome in terms of gait, balance,strenghts recovery, clinical performance, patient reported outcome measurements and overall recovery time in patients undergoing TotalHipArthroplasty with the aid of dedicated, modified instrumentation in order to properly access this modified route.Two patients groups will randomly be allocated in one of the two group with a computer generated 1:1 randomization table.Total number of subjects participating in the study:50.
