National data show a dramatic shift of TKA from inpatient to ambulatory surgery centers, with ASC volumes projected to exceed 2.1 million cases annually by 2040.
Preoperative frailty (higher Clinical Frailty Scale) independently predicted lateral compartment osteoarthritis progression and worse functional scores after medial UKA over a mean 70-month follow-up, aiding patient counseling.
In this long-term cohort study, preoperative psychiatric comorbidity was linked to higher failure rates, worse survivorship, and inferior patient-reported outcomes after hip arthroscopy for FAIS at 10 years.
In 370 PS-TKA patients followed over 4 years, changes in posterior tibial slope did not meaningfully affect functional outcomes, though increased slope modestly improved flexion; preoperative function was the strongest outcome predictor.
Patients with generalized ligamentous laxity undergoing hip arthroscopy for FAI had comparable long-term outcomes to matched controls, but those with very high Beighton scores (8-9) recovered more slowly with more early pain.
Among 179 hip-spine syndrome patients, those undergoing hip and spine surgery within one year of each other showed greater ODI improvement than those with longer intervals, suggesting benefit to shorter surgical spacing.
Medicare data show cementless TKA use rose sharply from 2016-2022, but Hispanic and dual-eligible (lower socioeconomic) patients had modestly lower odds of receiving this newer technique.
Preoperative CT-based quadriceps muscle phenotyping in knee OA patients identified three distinct muscle profiles that predicted differing functional recovery trajectories after TKA, supporting phenotype-guided rehabilitation.
Multicenter study found dysphagia is common after anterior cervical surgery (highest with corpectomy, lowest with disc arthroplasty), with baseline dysphagia, comorbidities, and female sex predicting persistence at 1 year.
A propensity-matched cohort study found technology-assisted primary THA had modestly higher index and 90-day episode-of-care costs than manual THA, with only slightly shorter hospital stays.
A history of GI bleeding before hip or knee arthroplasty was linked to higher 90-day medical complications and increased 2-year risk of mechanical loosening/revision (THA) or PJI/revision (TKA).
In symmetrically aligned bilateral TKA patients, coronal spinal imbalance strongly predicted which knee patients preferred, despite similar overall clinical improvement between groups.
In patients with anterior knee pain after non-resurfaced TKA, secondary patellar resurfacing improved outcome scores, and a novel GC radiographic index showed good discriminative accuracy for predicting AKP.
In 888 knee arthroplasties, roughly two-thirds of patients could not kneel or squat at one year, with higher BMI, lower preoperative ROM, poor kneeling confidence, older age, and female sex predicting inability.
In a UK cohort of 476,620 arthroplasties, VTE rates fell over time for hip and knee (but not clearly due to NICE guidelines), while a 2018 guideline update was linked to a 9% VTE reduction after shoulder arthroplasty.
Surgeons can improve healthy aging and reduce hospital returns by prescribing strength/balance training, screening for malnutrition, and leading bone health optimization.
In cadaveric TKA testing, lateral femoral joint-line distalization progressively increased LCL strain, with distalization beyond about 4 mm crossing a threshold linked to ligament microinjury and potential postoperative instability/dissatisfaction.
Pregnancy, Sexuality, and Total Hip Arthroplasty: Experiences of Women Younger than 45 Years.
In young women who underwent THA, most subsequent pregnancies and vaginal deliveries were safe, and nearly half reported improved sexual satisfaction post-surgery due to reduced pain and better mobility.
Diabetes is Associated with an Increased Risk of Arthrofibrosis Following Total Knee Arthroplasty.
In a large propensity-matched cohort, higher preoperative HbA1c levels were associated with progressively greater odds of early arthrofibrosis requiring MUA or lysis of adhesions within three months after TKA, highlighting the value of glycemic optimization.
Pyrocarbon Hemiarthroplasty Via Lateral Approach for the Treatment of PIP Osteoarthritis.
A lateral-approach pyrocarbon PIP hemiarthroplasty technique in 8 fingers produced good pain relief, improved range of motion, and better DASH scores for PIP osteoarthritis.
In a large national cohort of TKA patients over 75, dementia strongly predicted postoperative delirium and altered which other risk factors (falls, anemia, ASA class) mattered, suggesting a role for preoperative cognitive screening.
Swiss registry data on over 32,000 women ≥70 undergoing uncemented THA showed collared stems reduced periprosthetic fracture revision risk by roughly 92% compared to collarless designs.
A preoperative CTA-based algorithm with selective endovascular intervention (balloon catheters or arterial coiling) safely mitigated vascular injury risk during revision THA in patients with intra-pelvic implant migration.
Alignment Strategies in Total Knee Arthroplasty and How to Effectively Achieve Them.
Reviews and compares mechanical, anatomic, kinematic, and functional alignment strategies in TKA, showing similar outcomes overall while offering practical technical guidance for achieving each approach.
Metaphyseal Fixation in Revision Total Knee Arthroplasty.
This review highlights how modern porous metaphyseal cones and sleeves are increasingly used alongside allografts to manage bone defects and achieve durable fixation in revision TKA.
Limited evidence suggests air travel timing after THA/TKA doesn't clearly affect VTE risk, but long flights (>4 hours) warrant stronger prophylaxis and possible airline medical clearance.
Should Surgical Drains Be Used After Routine Primary Total Knee or Total Hip Arthroplasty?
An expert panel strongly recommends against routine use of surgical drains after primary total knee or hip arthroplasty.
Leg Length Discrepancy in Total Hip Arthroplasty: Not All Discrepancies Are Created Equal.
This update reviews leg length discrepancy after total hip arthroplasty, highlighting newer technologies to improve limb length control and how to distinguish true from perceived discrepancies in complex cases.
The current role of CT in total knee arthroplasty.
This review highlights how CT-based 3D imaging and navigation improve preoperative planning and intraoperative precision in TKA, though clinical outcome benefits still need further study.
This review outlines an algorithmic approach using serum and synovial markers for diagnosing periprosthetic joint infection across hip, knee, and shoulder, noting shoulder-specific criteria are still lacking.
Reviews emerging weight-loss options—including lifestyle changes, bariatric surgery, and GLP-1 agonists—to help arthroplasty surgeons guide preoperative weight optimization discussions with obese patients.
A review of implant cost-containment strategies finds price capitation and bundled payment models reduce total joint arthroplasty implant costs while shifting surgeons toward premium implants, raising physician autonomy concerns.
This narrative review synthesizes evidence-based decision-making factors—age, vascularity, displacement, and fixation versus arthroplasty choices—for managing femoral neck fractures.
