“…Consistent with the literature, by 16 weeks postsurgery, patients undergoing THA had an increase in gait velocity and stride length compared with before surgery (Table 4) [3,5,23,24,30,38,43,47]. We observed no major differences between patients and control subjects at 16 weeks postsurgery for these variables, suggesting improved range of motion and/or hip muscle strength after surgery and more efficient leg progression during gait [32].…”

Hip osteoarthritis leads to chronic pain and deteriorated joint function, which affect weightbearing and balance during gait. THA effectively restores hip function but it is not known whether THA restores balance during gait. We hypothesized patients would have greater frontal plane and smaller sagittal plane center of mass-center of pressure inclination angles preoperatively compared with control subjects, and THA would improve these inclination angles by 16 weeks postsurgery. Compared with control subjects, we observed greater frontal plane inclination angles and smaller sagittal plane angles preoperatively, indicating gait imbalance. These inclination angles were improved postoperatively, providing better balance control. Despite improvement, patients differed in frontal and sagittal plane inclination angles compared with control subjects. This suggests residual deficits in dynamic balance control in patients undergoing THA before and up to 4 months after surgery.

“…and shorter stride length than various control subjects up to 4 years [24,38,43] and even 10 years [3]. Trunk pitch (forward-backward) and roll (side-to-side) have been used to reflect balance control of patients undergoing THA during gait [26].…”

“…This was assumed to be a result of increased magnitude and duration of functional loading of the nonamputated extremity during day-to-day activities. Similarly, Loizeau et al (24) examined 4 postoperative patients who had undergone unilateral THR for end-stage OA and noted the presence of "mechanical dysfunction" based on altered energy absorbed or generated in the large joints of the nonoperated limb (24).…”

Objective. Subjects with unilateral end-stage hip osteoarthritis (OA) who undergo total hip replacement (THR) preferentially require subsequent replacement of the contralateral knee compared with the ipsilateral knee. We investigated whether this nonrandom, preferential evolution of lower extremity OA from the hip to the contralateral knee joint may be related to asymmetries in dynamic joint loading at the knees, particularly the peak external knee adduction moment, which has been associated with the progression of knee OA.Methods. Gait analysis was performed on 50 subjects who were preoperative for unilateral THR. Twenty-two of these subjects were reevaluated postoperatively 10-23 months after undergoing successful THR. At each analysis, dynamic joint loads in the contralateral knee were compared with those in the ipsilateral knee.Results. Prior to THR, the peak external knee adduction moment and peak medial compartment load were significantly higher in the contralateral knee. This asymmetry persisted after THR.Conclusion. Subjects with unilateral end-stage hip OA preferentially require subsequent replacement of the contralateral knee, as compared with the ipsilateral knee. Among patients with unilateral end-stage hip OA, the contralateral knee is subjected to higher dynamic joint loads than is the ipsilateral knee, and this asymmetric loading persists long after subjects have undergone successful THR. Biomechanical factors appear to be involved in the multiarticular evolution of OA of the lower extremities.

“…Isometric hip strength plays an important role in gait by contributing to trunk control and stability [16][17]. In a study of 15 THA subjects who were an average of 23 months post-THA, Sicard-Rosenbaum et al reported isometric muscle weakness of the quadriceps, abductors, and extensors as well as significantly decreased gait speed in THA subjects compared with age-and sex-matched control subjects [29].…”

“…Daubney and Culham examined lower-extremity muscle force and balance and found that isometric hip extensor strength was significantly lower in individuals who reported more falls [14]. Hip abductor weakness is also a major contributor to falls in older adults [15], and the importance of hip abductor strength in maintaining balance during gait is well established [16][17][18]. Increased hip flexion moment is associated with increased total hip joint force during stair climbing [19].…”

Abstract-We compared differences in isometric strength between older adults who have undergone elective unilateral total hip arthroplasty (THA) and completed rehabilitation with a population of community-dwelling older adults who have not had THA. The study was a cross-sectional design, and 22 unilateral THA subjects and 38 community-dwelling older adults participated. THA subjects received on average 13 outpatient or home-based physical therapy sessions before evaluation. THA subjects were evaluated 4 to 5 months postsurgery. We assessed isometric muscle strength by measuring peak hip torque per body weight with a robotic dynamometer during abduction, flexion, and extension. No significant performance differences were observed between operated and nonoperated hips of THA subjects. THA subject operated and nonoperated hips generated significantly less peak torque per body weight during flexion (p = 0.03) compared with community-dwelling older adult hips (THA subject operated hips = 6.96 ft-lb/lb, THA subject nonoperated hips = 8.26 ft-lb/lb, communitydwelling older adult hips = 11.56 ft-lb/lb). No significant differences were observed between THA subjects and community-dwelling older adults during hip extension (p = 0.55) or abduction (p = 0.17). At 4 to 5 months postsurgery, THA subjects were not at the same level of biomechanical performance as community-dwelling older adults. Significant strength deficits were found in THA subject operated versus nonoperated hips during isometric flexion. Additional or modified physical therapy that targets the hip flexors is recommended after THA.
