Temporospatial parameters of hip replacement patients ten years post-operatively

Abstract

While short-term outcome studies of patients following total hip arthroplasty (THA) have shown compromised walking ability, it is often assumed that temporospatial parameters will return to normal levels at long-term follow-up, especially for younger patients. Temporospatial parameters were determined for 149 THA patients selected arbitrarily from routine ten-year post-operative review clinics. Patients were divided into five age groups: 54-64, 65-69, 70-74, 75-79 and over 80 years. The parameters of speed, step length, stride length and cadence were measured. All age groups displayed significantly reduced velocity, step length and stride length compared to an age-matched normal group. There was no difference in most of the temporospatial parameters between the age groups. This study shows that even younger THA patients at long-term follow-up do not regain normal age-matched walking characteristics.Résumé Alors que les études présentant les patients ayant bénéficié d'une prothèse totale de hanche montrent une altération immédiate des possibilités de marche, il semble assuré que les paramètres temporospatiaux se normalisent après un long suivi, spécialement chez les patients jeunes. Ces paramètres temporospatiaux ont été déterminés chez 149 patients sélectionnés, de façon arbitraire et routinière après avoir été revus 10 ans après l'intervention chirurgicale. 10 ans après l'intervention, les patients ont été divisés en 5 groupes d'âge: 54-64, 65-69, 70-74, 75-79 et après 80 ans. Les différents paramètres de marche, vitesse, escalier, cadence, etc. ont été mesurés. Quel que soit l'âge, il y a une diminution significative de la rapidité, de la longueur du pas et de longueur de foulée comparés à un groupe témoin normal. Il n'y a pas la plupart du temps de différence, des paramètres temporospatiaux entre les différ-ents groupes d'âge. Cette étude montre que, même chez les patients jeunes, la mise en place d'une prothèse totale de hanche, ne permet pas, à long terme, de récupérer tous les paramètres normaux de la marche.

Comparison of total hip arthroplasty surgical approaches by Principal Component Analysis

“…Significant reductions occurred in THA patients compared to controls, confirming that the surgery does not completely restore normal gait, regardless of the adopted surgical approach (Bennett et al, 2009;Foucher et al, 2007;Lamontagne et al, 2011;Madsen et al, 2004;Martin et al, 2011;Meneghini et al, 2008;Queen et al, 2011). As expected, PCA was able to identify temporal differences from the CON group, such as the time delay in the patterns of ANT variables, not previously identified by traditional analyses.…”

“…Despite significant improvements in gait patterns, gait adaptations persist after total hip arthroplasty (THA) in both short and long term follow-up (Bennett et al, 2009;Foucher et al, 2007). The choice of surgery can influence postoperative gait; with this in mind, this study compares two different surgical approaches: the modified direct lateral approach (Mulliken et al, 1998) and the single-incision anterior approach (Matta et al, 2005).…”

Total hip replacement with a collarless polished cemented anatomic stem: clinical and gait analysis results at ten years follow-up

“…None had patients walking freely in a corridor (without cameras or specific walkways) as in our study. The observed decreases in cadence, stride length, speed and all ROM from five to ten years follow-up in our study are similar to those reported by Bennett et al [20,21]. However, THR patients in our study walked faster and with a greater stride length (Table 5).…”

“…Three studies analysed gait parameters of THR patients at a follow-up of at least ten years (Table 5) [9,20,21]. None had patients walking freely in a corridor (without cameras or specific walkways) as in our study.…”

“…Bennett et al [20,21] performed their gait analysis at one self-selected speed on a walkway with six cameras. Kyriazis and Rigas [9] used a conductive walkway.…”
