Factors influencing the outcomes of minimally invasive total hip arthroplasty: a systematic review

Abstract

Introduction The present systematic review investigated possible factors which may influence the surgical outcome of minimally invasive surgery for total hip arthroplasty (MIS THA). Methods In January 2022, the Embase, Google Scholar, PubMed, and Scopus databases were accessed. All the clinical trials investigating the clinical outcome of MIS THA were considered. Results Data from 9486 procedures were collected. Older age was moderately associated with greater Visual Analogue Scale (VAS) (P = 0.02) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) (P = 0.009) at last follow-up, and shorter surgical duration (P = 0.01). Greater body mass index (BMI) at baseline was moderately associated with greater cup anteversion (P = 0.0009), Oxford Hip Score (OHS) at last follow-up (P = 0.04), longer surgical duration (P = 0.04), increased leg length discrepancy (P = 0.02), and greater rate of infection (P = 0.04). Greater VAS at baseline was weakly associated with greater VAS at last follow-up (P < 0.0001), total estimated blood lost (P = 0.01), and lower value of Harris Hip Score (HHS) (P = 0.0005). Greater OHS at baseline was associated with greater post-operative VAS (P = 0.01). Greater WOMAC at baseline was associated with lower cup anteversion (P = 0.009) and greater VAS (P = 0.02). Greater HHS at baseline was associated with shorter hospitalisation (P = 0.001). Conclusion Older age and greater BMI may represent negative prognostic factors for MIS THA. The clinical outcome is strongly influenced by the preoperative status of patients.

Patient‐related Predictors for the Functional Outcome of SuperPATH Hemiarthroplasty versus Conventional Approach Hemiarthroplasty: A Systematic Review and Meta‐regression Analysis of Randomized Controlled Trials

“…A 2022 systematic review of 9486 THAs investigated possible factors that may influence the surgical outcome of minimally invasive THA. It found that older age and higher BMI may be negative prognostic factors for minimally invasive THA and that the clinical outcome is strongly influenced by patients' preoperative status 43 . A 2019 retrospective study of 116 patients found that return to work after hip and knee arthroplasty was not significantly influenced by the type of surgery or the physical demands of the job.…”

Patients returned to work between 5.9 and 7.7 weeks after hip/knee replacement.…”

Comparison of clinical outcomes of supercapsular percutaneously-assisted approach total hip arthroplasty versus conventional posterior approach for total hip arthroplasty in adults: a systematic review and meta-analysis

“…By observing the results reported, most studies reported a shorter length of hospital stay for SP, so we supposed that the analysis result was plausible and the effect of publication bias was small. There existed a strong publication bias in the outcomes of the time to start activity postoperatively and incision length, both of which could be influenced by differences in bone cement, differences in hip implants, and differences in the patient's underlying diseases, age, gender, and BMI to some extent [ 67 ]. For example, women had longer incision lengths than men; heavier patients had longer incision lengths than those with less weight; patients with more underlying diseases required a longer time to get out of bed.…”

Prognostic Factors for Postoperative Chronic Pain after Knee or Hip Replacement in Patients with Knee or Hip Osteoarthritis: An Umbrella Review

“…Another 19 were excluded because they focused on preoperative treatment or postintervention efficacy or effectiveness [13][14][15][16][17][18][19][20], did not report results about postoperative chronic pain [21][22][23][24][25], had no systematic review [26], overlooked preoperative risk factors [7], or investigated different surgical approaches [27][28][29][30]. Finally, a total of 18 reviews [31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48] were included in the umbrella (Figure 1).…”
