Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is an observational prospective study aimed to assess the lower limbs motor and functional recovery in patients who underwent to unilateral THA respect to simultaneous bilateral THA, in early postoperative phase.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Introduction: Total hip arthroplasty (THA) represents a successful treatment for several hip joint pathologies. In case of bilateral hip joint involvement, the advancements in surgical techniques have made the development of bilateral THA surgery possible through one-stage procedure. This approach seems to be as safe as unilateral THA and safer than two-stage bilateral THA, but few studies considering functional outcomes in these patients without exploring outcomes linked to their motor and functional performance.

Objective: the aim of the study is to assess the lower limbs motor and functional recovery in patients who underwent to unilateral THA respect to simultaneous bilateral THA, in early postoperative phase.

Methods: 20 patients underwent to unilateral THA and 20 patients underwent to simultaneous bilateral THA will be recruited in the study. The partecipants will be aged from 40 to 65 years old, they will be undergone to primary THA for arthritis and the will be able to walk for 50 m without aids. Patients with severe dysplasia (Crowe III and IV), anchylosis, sub-anchylosis or surgical fusion of the coxophemoral joint, with traumatic event, or previous femoral and / or pelvic osteotomy, will be excluded from the study. Weight distribution and postural stability will be evaluated asking to participants to stay on two stabilometric platform with open eyes and closed eyes for 45 seconds. Gait analysis will be used to evaluate the spatio-temporal gait parametres and the ankle, knee, hip and pelvic kinematic. Pain during walking and patients' walking ability will be also evaluated throught Numeric Rating Scale (NRS) and Timed Up and Go test (TUG). Outcome measures will be collected the day before surgery, after three, seven and about forty days after surgery, except for gait analysis and Time Up and Go tests, which will not be recorded after three days.

Statistical analysis: normality and homogeneity of demographic variables and outcome measures at the baseline will be verified. Intergroup and intra-group post-intervention differences related to outcome measures will be investigated through ANOVA for repeated measurements including post hoc analysis.
