“…A modified Helen-Hayes marker set was used for testing. This marker set has been previously used when testing patients with ankle [12][13][14][15], hip [16][17][18][19], and knee OA [20,21], as well as healthy control subjects [22]. Each subject was asked to stand within the capture volume to record a static standing trial.…”

“…More recently, prosthetic hip reaction forces (hrf, —also called hip contact forces—hcf) can be computed in silico for biomechanical analyses after THR, which would be difficult to perform in vivo . In this context, symmetry indices are often used as outcome measures since an increase in symmetry leads to a more equally distributed load scenario in the artificial hip joint . Therefore, symmetry of the hrf estimates how much the specific surgical approach influences the opposite (untreated) side.…”

The hip reaction angles (hra-orientation of hrf) estimate if critical edge (or rim) loading occurs during a certain motion.…”

Influence of minimally invasive total hip replacement on hip reaction forces and their orientations

Minimally invasive surgery (MIS) is becoming increasingly popular. Supporters claim that the main advantages of MIS total hip replacement (THR) are less pain and a faster rehabilitation and recovery. Critics claim that safety and efficacy of MIS are yet to be determined. We focused on a biomechanical comparison between surgical standard and MIS approaches for THR during the early recovery of patients. A validated, parameterized musculoskeletal model was set to perform a squat of a 50th percentile healthy European male. A bilateral motion was chosen to investigate effects on the contralateral side. Surgical approaches were simulated by excluding the incised muscles from the computations. Resulting hip reaction forces and their symmetry and orientation were analyzed. MIS THR seemed less influential on the symmetry index of hip reaction forces between the operated and nonoperated leg when compared to the standard lateral approach. Hip reaction forces at peak loads of the standard transgluteal approach were 24% higher on the contralateral side when compared to MIS approaches. Our results suggest that MIS THR contributes to a greater symmetry of hip reaction forces in absolute value as well as force-orientation following THR.

“…Gait analysis can be used to objectify clinical impressions and results of differences in isolated kinematics or kinetics at specific time-points during the gait cycle are commonly reported [41][42][43]. The current study is the first to investigate the global effect of total hip replacement surgery on gait pattern changes at several postoperative assessment time-points by using the The current trend is that patients undergoing total hip arthroplasty for osteoarthritis become younger and more active [44].…”

“…In a study by Queen et al [41], HRA patients demonstrated improved hip extension and higher limb loading when compared with LHA patient's at 18-months. HRA patients also demonstrated greater improvements in hip kinematics, indicating more normative joint loading, compared with 28 mm THA at 3-months [45].…”
