Early Total Hip Arthroplasty is a Cost-Effective Treatment for Severe Radiographic Slipped Capital Femoral Epiphysis Over an Individual's Lifetime. J Arthroplasty 2022; 38:798-805. [PMID: 36470363 DOI: 10.1016/j.arth.2022.11.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2022] [Revised: 10/30/2022] [Accepted: 11/28/2022] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Slipped capital femoral epiphysis (SCFE) causes degenerative changes warranting total hip arthroplasty (THA) in approximately 50% of patients by age 60 years. For severe SCFE, a reorienting intertrochanteric osteotomy (ITO) following in situ pinning (ISP) can decrease impingement with hip flexion, but by altering proximal femoral geometry, complicates subsequent conversion THA. We hypothesized that increasing implant survivorship would affect the most cost-effective treatment strategy (ISP followed by ITO [ISP + ITO] with later THA versus ISP alone [ISPa] with earlier THA) over a patient's lifetime. METHODS A state-transition Markov model was constructed to analyze the cost-effectiveness of either ISPa or ISP + ITO over a 60-year time horizon for children who have severe, stable SCFE. Transition probabilities associated with implant and native hip survivorship, state utilities, and costs were derived from the literature. Sensitivity analyses assessed the model robustness. Incremental cost-effectiveness ratios (ICERs) were compared to a societal willingness to pay (WTP) of $100,000 per quality-adjusted life year (QALY). RESULTS Over a 60-year horizon, ISPa was costlier ($291,836) than ISP + ITO ($75,227) but achieved overall better outcomes (51.4 QALYs ISPa versus 48.7 QALYs ISP + ITO), rendering ISPa cost-effective with an ICER of $80,980/QALY. Implant survivorship and time horizon were sensitive variables. CONCLUSION Based upon current implant performance, ISPa with subsequent earlier THA is cost-effective when considering an individual's life expectancy and thereby deserves consideration in patients who have severe SCFE. Without clear level 1 clinical data, our economic model considers a difficult problem, while providing families and clinicians with a framework for understanding treatment options. LEVEL OF EVIDENCE Economic and decision analysis, Level III.

[PMID: 35942332 PMCID: PMC9356201 DOI: 10.1016/j.jor.2022.07.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2022] [Revised: 06/13/2022] [Accepted: 07/12/2022] [Indexed: 10/17/2022] Open
Abstract
Background Modified anatomy of dysplastic hips, bone defects and previous operations make THA (total hip arthroplasty) in patients with hip dysplasia a technically challenging procedure. Methods One hundred and ten patients (mean 49.2 years of age, range 19-76, female:103, male:7) underwent 122 subsequent hip arthroplasties from 2012 to 2019. These patients were reviewed at least two years after THA. Plain radiography was used to determine Crowe classification of the affected hips. Fifty-three patients had an operation in childhood before THA was done (mean 47.0 years of age, standard deviation 8.3, range 19-62) and formed the "operated group". Among these patients, there were Chiari pelvic osteotomies, periacetabular osteotomies, femoral osteotomies, greater trochanter distalizations and soft tissue operations. Fifty-seven were not operated in childhood (mean 52.3 years of age, standard deviation 10.9, range 19-76) and formed the "non operated group". The functional status of the patients was assessed with the Oxford Hip Score (OHS). Results 122 total hip arthroplasties were performed using uncemented femoral and acetabular components. There were 13 major complications identified. Ten were in the "operated group", of which 5 needed revision surgery. Only 3 were in the "non operated group", with no need for revision. Aseptic loosenings of the femoral component were seen in the patients that had femoral osteotomy done in childhood. Acetabular component migration and intrapelvic migration occurred due to the initial malposition and lack of osteointegration, thus requiring early revision after just 6 months. Other major complications were peroneal palsy, deep periprosthetic infection, severe trochanteritis and intraoperative femoral fracture. OHS was significantly higher in the "non operated group" 42.3 (10-48), opposed to 39.1 (10-48) in the "operated group" (p 0.017). Conclusion Corrective osteotomies in childhood are a risk factor for complications and lower medium-term survivorship of the THA in hip dysplasia patients.

J Hip Preserv Surg 2022; 9:197-205. [PMID: 35992024 PMCID: PMC9389913 DOI: 10.1093/jhps/hnac035] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2022] [Revised: 04/19/2022] [Accepted: 07/27/2022] [Indexed: 11/14/2022] Open
Abstract
The purpose of this study was to evaluate the outcomes of total hip arthroplasty (THA) following less invasive hip-preserving procedures (LIHPs) and present a critical overview of the literature to aid in better result interpretation. The search time was from the establishment of the database to September 2021, and the outcome indicators were extracted and analyzed by Cochrane Collaboration Review Manager software (RevMan version 5.4). Finally, 10 articles were included in this meta-analysis by searching Chinese databases and English databases. Three of them were published in Chinese, and the remaining studies were published in English. LIHP was further divided into the tantalum rod implantation group and the non-tantalum rod implantation group. The results showed that prior tantalum rod implantation increased the difficulty of conversion to THA, which was reflected mainly in the longer operative time [weighted mean difference (WMD) = 24.50, 95% confidence interval (CI) = 14.09–34.91, P < 0.00001] and greater intraoperative blood loss (WMD = 114.74, 95% CI = 33.52–195.96, P = 0.006), while no significant difference was found between the non-tantalum rod implantation group and the control group. Simultaneously, easier intraoperative fracture [odds ratio (OR) = 5.88, 95% CI = 0.93–37.05, P = 0.06] and stem malalignment (OR = 4.17, 95% CI = 1.18–14.71, P = 0.03) in the LIHP group tended to be observed than in the control THA group. However, there was no significant difference in cup anteversion and inclination angle, ectopic ossification, postoperative Harris Hip Score and survivorship between the LIHP group and the control group. Although LIHP increased the difficulty of the conversion to THA, it does not detrimentally affect the clinical results of subsequent THA in the mid-term follow-up.

Total hip arthroplasty after rotational acetabular osteotomy for developmental dysplasia of the hip: a retrospective observational study. BMC Musculoskelet Disord 2022; 23:646. [PMID: 35794611 PMCID: PMC9258082 DOI: 10.1186/s12891-022-05597-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2022] [Accepted: 06/28/2022] [Indexed: 11/10/2022] Open
Abstract
Background Total hip arthroplasty after osteotomy is more technically challenging than primary total hip arthroplasty, especially concerning cup placement. This is attributed to bone morphological abnormalities caused by acetabular bone loss and osteophyte formation. This study aimed to investigate the clinical and radiological outcomes of total hip arthroplasty after rotational acetabular osteotomy compared with those of primary total hip arthroplasty, focusing mainly on acetabular deformity and cup position. Methods The study included 22 hips that had undergone rotational acetabular osteotomy and 22 hips in an age- and sex-matched control group of patients who underwent total hip arthroplasties between 2005 and 2020. We analyzed cup abduction and anteversion; lateral, anterior, and posterior cup center–edge angle; hip joint center position; femoral anteversion angle; and presence of acetabular defect using postoperative radiography and computed tomography. Operative results and clinical evaluations were also analyzed. Results The clinical evaluation showed that the postoperative flexion range of motion was lower in total hip arthroplasty after rotational acetabular osteotomy than in primary total hip arthroplasty, although no significant difference was noted in the postoperative total Japanese Orthopedic Association hip score. The operative time was significantly longer in the rotational acetabular osteotomy group than in the control group, but there was no significant difference in blood loss. The lateral cup center–edge angle was significantly higher and the posterior cup center–edge angle was significantly lower in the total hip arthroplasty after rotational acetabular osteotomy, suggesting a posterior bone defect existed in the acetabulum. In total hip arthroplasty after rotational acetabular osteotomy, the hip joint center was located significantly superior and lateral to the primary total hip arthroplasty. Conclusions In total hip arthroplasty after rotational acetabular osteotomy, the cup tended to be placed in the superior and lateral positions, where there was more bone volume. The deformity of the acetabulum and the high hip center should be considered for treatment success because they may cause cup instability, limited range of motion, and impingement.

Does prior core decompression have detrimental effect on subsequent total hip arthroplasty for osteonecrosis of the femoral head: A systematic review and meta-analysis. Orthop Traumatol Surg Res 2020; 106:1553-1560. [PMID: 33189665 DOI: 10.1016/j.otsr.2020.07.004] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2019] [Revised: 07/23/2020] [Accepted: 07/31/2020] [Indexed: 02/03/2023]
Abstract
BACKGROUND Core decompression (CD) is effective in relieving pain and delaying the progression to total hip arthroplasty (THA) for osteonecrosis of the femoral head (ONFH). However, the influence of CD on subsequent THA has not yet been established. Therefore, we performed this systematic review to answer: does prior CD have detrimental effect on subsequent THA for ONFH, especially with regards to survivorship and functional results, as well as perioperative and postoperative complications. PATIENTS AND METHODS After registration on PROSPERO (CRD42019118861), literature published up to and including November 2018 was searched in the PubMed, Embase and Cochrane library databases with predetermined terms. Comparative studies on the clinical outcomes between conversion to THA with prior CD (the Prior CD group) and primary THA (the Control group) for ONFH were included. The outcomes of interest included survivorship free from revision, the postoperative functional performance, perioperative and postoperative complications. Data was extracted systematically and a meta-analysis was performed. RESULTS Overall, 5 retrospective cohort studies with 110 hips were identified for the Prior CD group and 237 hips were identified for inclusion in the Control group. All of the studies were of high quality in terms of the Newcastle-Ottawa Scale. No difference in the rate of revision between the two groups (2/42 (4.8%) vs. 4/160 (2.5%); RR=1.92; 95% CI=0.34 to 10.75; p=0.46) was detected after a minimum two-year follow-up. The mean postoperative Harris Hip Score was similar between the two groups in all 5 studies. The two groups experienced similar blood loss (Mean difference=12.17ml; 95% CI= -15.28 to 39.61ml; p=0.38). Moreover, intraoperative fracture was increased in the Prior CD group, though this did not reach statistical significance (3/31 (9.7%) vs. 0/55 (0.0%); RR=7.05; 95% CI=0.82 to 60.78; p=0.08). Similarly, osteolysis or radiolucent lines were more likely to occur in the Prior CD group without statistical significance (9/81 (11.1%) vs. 6/200 (3.0%); RR=3.14, 95% CI=0.98 to 10.06; p=0.05). DISCUSSION The present evidence indicated that prior CD does not detrimentally affect the survivorship nor hip scores of subsequent THA. Attention should be paid, however, to the potential for intraoperative fracture, postoperative osteolysis or radiolucent lines. LEVEL OF EVIDENCE III; systematic review and meta-analysis of level III retrospective comparative studies.

J Arthroplasty 2020; 35:3638-3643. [PMID: 32674940 DOI: 10.1016/j.arth.2020.06.047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2020] [Revised: 06/05/2020] [Accepted: 06/16/2020] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Controversy exists whether previous pelvic osteotomies have negative effects on total hip arthroplasty (THA). This study evaluates the implant survival and patient-reported outcomes of THA after previous Chiari pelvic osteotomy (CPO). METHODS Data on 301 THAs after CPO were collected through clinical and radiological follow-up examinations and telephone interviews. The Kaplan-Meier survivorship analysis depicts implant survival. RESULTS Of this consecutive series of 1536 CPOs, follow-up was completed in 405 patients with 504 CPOs after a mean time of 36 years (±8; range, 22-54 years). At follow-up, 301 hips (60%) had already undergone THA. The overall survival of THA with revision as an end point after 10, 20, and 25 years was 93%, 76%, and 68%, respectively. The revision rate was 12%. The average period between THA and revision surgery was 9.6 years (±6.1; 4 months-25.4 years). The patient's age at revision was 57.9 years (±10; 33.2-78.5 years). Aseptic loosening was the most common of the known reasons for revision surgery. CONCLUSION This retrospective study supports the hypothesis that prior CPO does not compromise the prerequisites for successful THA at a later stage. Survival rates of the implanted prosthesis are comparable to primary implanted hips, as overall survival was 93% after 10 years.
