To survey high-volume hip arthroscopists regarding their current indications for labral reconstruction, graft preference and technique. In May 2018, a cross-sectional based survey was conducted on high-volume hip arthroscopists. A high-volume surgeon was defined as an orthopaedist who had case experience ranging from 50 to 5000 hip arthroscopies performed annually. The survey included their current indications for labral reconstruction, graft preference and technique. Twelve high-volume surgeons successfully completed the questionnaire. The mean arthroscopic procedures performed by the surgeons annually was 188.7 (range 60–350). Four surgeons (33.3%) performed <5 labral reconstruction cases per year, three (25.0%) 5–10 cases per year, two (16.7%) 11–15 cases per year and three (25.0%) over 20 cases per year. Of the 12 surgeons, 11 (91.6%) would reconstruct in certain primary settings and 100% would reconstruct in revision settings. In the primary setting, the main indications for reconstruction were poor quality labral tissue, calcified labrum and hypoplastic labrum. None of the surgeons recommended labral reconstruction for reparable labral tears in primary cases. In primary cases of irreparable labra, 58.3% of the surgeons favoured reconstruction over debridement. In revisions, 100% of the surgeon favoured reconstruction over debridement; 91.7% chose an allograft option versus an autograft alternative. Amongst high-volume arthroscopists, labral reconstruction was considered a valuable technique to restore labral function. Labral reconstruction was more often advocated in revision than in primary settings. Allograft was the preferred choice for reconstruction. Excision of the labral tissue prior to reconstruction was favoured over augmentation. Fewer surgeons performed circumferential reconstruction than segmental reconstruction.
Background:
Total hip arthroplasty (THA) is the benchmark surgical treatment of advanced and symptomatic hip osteoarthritis. Preliminary evidence suggests that the robotic arm-assisted (RAA) technology yields more accurate and reproducible acetabular cup placement, which may improve survival rate and clinical results, but economic considerations are less well-defined. The purpose of this study was to compare the cost effectiveness of the RAA THA with manual THA (mTHA) modalities, considering direct medical costs and utilities from a payer's perspective.
Methods:
A Markov model was constructed to analyze two potential interventions for hip osteoarthritis and degenerative joint disorder: RAA THA and mTHA. Potential outcomes of THA were categorized into the transition states: infection, dislocation, no major complications, or revision. Cumulative costs and utilities were assessed using a cycle length of 1 year over a time horizon of 5 years.
Results:
RAA THA cohort was cost effective relative to mTHA cohort for cumulative Medicare and cumulative private payer insurance costs over the 5-year period. RAA THA cost saving had an average differential of $945 for Medicare and $1,810 for private insurance relative to mTHA while generating slightly more utility (0.04 quality-adjusted life year). The preferred treatment was sensitive to the utilities generated by successful RAA THA and mTHA. Microsimulations indicated that RAA THA was cost effective in 99.4% of cases.
Conclusions:
In the Medicare and private payer scenarios, RAA THA is more cost effective than conventional mTHA when considering direct medical costs from a payer's perspective.
