Stacked-Cone Constructs for Extensive Tibial and/or Femoral Bone Loss in Complex Primary and Revision TKA: A Multicenter Analysis of 84 Cases

Jun 24, 2026

This study investigates the 5-year outcomes of stacked metaphyseal cone constructs used to manage extensive tibial and/or femoral bone loss during complex primary or revision total knee arthroplasty (TKA). The authors found that while the constructs demonstrated a high survivorship rate free from aseptic loosening (91.7%), all-cause reoperations and revisions were relatively common, highlighting the challenges associated with this patient population.

Shaping Modern Practice in South Korea: A Centennial Review of Orthopaedics at Severance Hospital and Yonsei University College of Medicine

Jun 23, 2026

This review aims to commemorate and analyze the historical evolution of orthopaedic practice at Severance Hospital and Yonsei University College of Medicine over the past century. It highlights key milestones, including the establishment of modern orthopaedics in Korea, the founding of the independent Department of Orthopaedic Surgery, and the department's contributions to clinical excellence and academic research within the field.

Alarmingly High Rates of Complications and Refracture Among Patients with Early Periprosthetic Femoral Fracture Within 30 Days After THA

Jun 17, 2026

This study aims to compare the outcomes of patients who experience periprosthetic femoral fractures within 30 days after total hip arthroplasty (THA) to those who sustain fractures at later time points. The findings reveal that early fractures are associated with significantly higher rates of complications, refracture, and reoperation within two years, highlighting the need for targeted prevention and intervention strategies for these patients.

Minimal and Substantial Improvement Thresholds for Oxford Scores Following Primary Hip and Knee Replacement Based on Patient Satisfaction

Jun 17, 2026

The authors aimed to determine whether the Oxford Hip Score (OHS) and Oxford Knee Score (OKS) can effectively predict patient satisfaction following primary hip and knee replacements, and to establish thresholds for minimal clinically important difference (MCID) and substantial clinical benefit (SCB) to inform value-based healthcare policies. They identified specific postoperative score thresholds for both the OHS and OKS that could guide decision-making in clinical practice. The study found that preoperative scores were not reliable predictors of satisfaction, highlighting the importance of postoperative assessments.

The Variable Axis Knee Prosthesis: A Legacy of Dr. David G. Murray

Jun 17, 2026

This paper explores the legacy and impact of Dr. David G. Murray's Variable Axis knee prosthesis, which was developed in the early 1970s as the first unconstrained cruciate-substituting knee prosthesis. The authors aim to highlight the innovative features of this prosthesis, including its unique design and modular components, and its influence on subsequent knee prosthetic designs despite its eventual replacement by Total Condylar-type designs.

Twenty-Five Years of Global Private Investment in Pediatric Orthopaedic Start-ups

Jun 17, 2026

The authors investigate the trends and challenges associated with private investment in pediatric orthopaedic start-ups over the past 25 years, comparing these investments to those in adult orthopaedics. They find that while pediatric start-ups receive significantly less investment—only 10% of total orthopaedic funding—their ability to secure subsequent capital is comparable to that of adult-focused companies. This study highlights the need for increased financial support in pediatric orthopaedic innovation to improve care for children.

Heading Toward a Different Future: The Microbiome, Dysbiosis, Microbial Translocation, and Beyond

Jun 17, 2026

This paper explores the emerging concept of the gut-joint axis, investigating how dysbiosis and microbial translocation from the gut may contribute to joint diseases. The authors aim to understand the mechanisms linking gut health to these conditions and propose that future research should focus on developing therapeutic strategies to restore gut barrier integrity and microbiota diversity. They emphasize the need for advanced research methodologies, such as next-generation sequencing, to facilitate this understanding.

Predictors of Loss to Long-Term Follow-up After Shoulder Surgery

Jun 16, 2026

The authors aimed to identify factors influencing loss to follow-up after shoulder surgery, hypothesizing that older patients would have higher follow-up rates while those undergoing instability surgery would have lower rates. Their analysis of 1,028 patients revealed that older age, undergoing arthroplasty, and being insured by Medicare were associated with higher follow-up completion, while younger age and missing preoperative pain scores predicted loss to follow-up. The findings suggest a need for targeted strategies to enhance follow-up rates among younger patients and those with specific insurance types.

Incisional Infiltration of Liposomal Bupivacaine in Geriatric Hip Fracture Surgery: A Randomized Parallel-Group Trial

Jun 16, 2026

The authors aimed to determine whether local incisional infiltration of liposomal bupivacaine (LB) provides clinically relevant analgesic benefits in geriatric patients undergoing hip fracture surgery compared to standard multimodal analgesia without LB. Although the primary outcome of resting pain at 48 hours postoperatively did not show significant differences between groups, several secondary outcomes indicated improved pain management and sleep quality in the LB group. Ultimately, the findings do not support the routine use of LB in this surgical context, highlighting the need for further research.

The Effect of Bariatric Surgery on Complication Risk Following Total Hip Arthroplasty in Patients with Morbid Obesity

Jun 16, 2026

This study aimed to evaluate the impact of prior bariatric surgery on the risk of surgical complications following total hip arthroplasty (THA) in patients with morbid obesity. The findings revealed that patients who had undergone bariatric surgery experienced a higher risk of major complications, particularly periprosthetic joint infections, and did not benefit from reduced revision risk or lower readmission rates. Consequently, the authors suggest that delaying THA for bariatric surgery may not be justified, highlighting the need for alternative obesity management strategies.
