Total hip arthroplasty using a posterior minimally invasive approach – results after six years

Abstract

ObjectiveTo evaluate the medium-term clinical–functional results (minimum follow-up of six years) from total uncemented hip arthroplasty performed by means of a posterior minimally invasive access, in comparison with the traditional right lateral access.MethodsIn a comparative prospective study, 224 adult patients underwent elective total hip arthroplasty due to a diagnosis of primary or secondary osteoarthrosis. A group of 103 patients with posterior minimally invasive access was compared with a group of 121 patients with the traditional right lateral access. The mean length of follow-up among the patients of this sample was 7.2 years. We evaluated the clinical–functional and radiographic results and occurrences of loosening, along with any complications that occurred, with a minimum follow-up of six years.ResultsThe clinical–functional analyses before the surgical procedure and six years afterwards were similar in the two groups (p = 0.88 and p = 0.55). One patient in the minimally invasive group underwent revision of the acetabular component and two patients in the control group underwent the same procedure (p = 0.46). The Trendelenburg clinical test, which showed weakness of the hip abductor musculature, was present in five patients operated using the traditional lateral route and absent in all those who underwent the minimally invasive procedure (p = 0.06). There was no difference regarding the radiographic parameters obtained, either in acetabular or in femoral positioning (p = 0.32 and p = 0.58).ConclusionsThe medium-term clinical and radiographic results and the complication rates were similar between the patients who underwent total hip arthroplasty by means of the posterior minimally invasive access and those with the traditional lateral access.

Evaluation of Acute Pain in Patients Undergoing Total Hip Arthroplasty: A Cohort Study

“…Regarding the age variable, the majority of the sample was middle‐aged, which agrees with previous studies (da Silva et al., ; Vicente, Miyahara, Luzo, Gurgel, & Croci, ). This relatively low mean age may have a positive effect on recovery, as well as on complications inherent to arthroplasty wear and tear, given the theoretically greater physical activity of these patients (Vicente et al., ).…”

Total hip arthroplasty complications in patients with or without controlled diabetes mellitus during hospitalization

“…The literature is divergent as to the most operated side in THA; in some studies, the involvement of the left or right side was similar 22, 23. In turn, in some studies the most operated side was the right, 69.2% and 55.6% respectively 24, 25.…”

Which approach of total hip arthroplasty is the best efficacy and least complication?

“…Most studies were from USA, Europe and China. The numbers of included studies were thirteen PA vs DAA[ 53 , 54 , 56 - 58 , 69 , 75 , 84 , 85 , 87 , 88 , 94 , 96 ], thirteen LA vs DAA[ 55 , 59 , 61 , 67 , 71 , 74 , 76 , 77 , 79 , 81 , 82 , 86 , 97 ], seven PA vs LA[ 63 , 65 , 83 , 90 - 92 , 95 ], one PA vs two-incision[ 60 ], one PA vs LA vs two-incision[ 72 ], three LMIS vs LA[ 66 , 70 , 80 ], seven DSA/SuperPath vs PA[ 18 , 19 , 64 , 68 , 73 , 78 , 93 ] and two DSA/SuperPath vs LA[ 62 , 89 ]. The mean age was 51 to 76 years, BMI 21-31 kg/m 2 , 13%-65% male and 20%-100% had hip osteoarthritis (Table 2 ).…”
