Abstract EN
Objective.
To compare center of mass (COM) compensation in the frontal and sagittal plane during gait in patients with large diameter head total hip arthroplasty (LDH-THA) and hip resurfacing (HR).
Design.
Observational study.
Setting.
Outpatient biomechanical laboratory.
Participants.
Two groups of 12 patients with LDH-THA and HR recruited from a larger randomized study and 11 healthy controls.
Interventions.
Not applicable.
Main Outcome Measures.
To compare the distance between the hip prosthetic joint center (HPJC) and the COM.
The ratio (RHPJC-COM) and the variability (CVHPJC-COM) were compared between groups.
Hip flexor, abductor, and adductor muscle strength was also correlated between groups while radiographic measurements were correlated with the outcome measures.
Results.
In the frontal plane, HR shows less variability than healthy controls at push-off and toe-off and RHPJC-COM is correlated with the muscle strength ratios (FRABD) at heel contact, maximal weight acceptance, and mid stance.
In the sagittal plane, LDH-THA has a higher RHPJC-COM than healthy controls at push-off, and CVHPJC-COM is significantly correlated with FRFLEX.
Conclusions.
One year after surgery, both groups of patients, LDH-THA and HR, demonstrate minor compensations at some specific instant of the gait cycle, in both frontal and sagittal planes.
However, their locomotion pattern is similar to the healthy controls.
