Arthroscopic Removal of Loose Glenoid Component in Anatomic Total Shoulder Arthroplasty.

Aseptic glenoid component loosening after anatomic total shoulder arthroplasty remains an important cause of late clinical failure and revision surgery. We present here the surgical technique of all-arthroscopic removal and glenoid bone grafting. Arthroscopic removal of a loose glenoid component and bone grafting of the glenoid defect without dermal allograft preserves glenoid bone stock and obviates the need for multiple suture anchors to hold the graft in place.

Return to Sports in Patients Aged 50 Years or Younger After Robotic-Assisted Patellofemoral Arthroplasty: A 10-Year Experience Reporting High Clinical Benefits and High Patient Satisfaction With Return to an Active Lifestyle.

Background: Limited data are available on return to sports and patient psychometric ratings of success after patellofemoral arthroplasty (PFA) in younger patients with high expectations to return to an active lifestyle.

Purpose/hypothesis: The purpose of this article was to determine the role of PFA and its success in meeting patient expectations regarding the return to low-impact recreational sports and an active lifestyle in younger, active patients. It was hypothesized that PFA would allow younger patients to return to low-impact sports and an active lifestyle and achieve high patient psychometric ratings.

Arthroscopic Repair of Retracted Large and Massive Rotator Cuff Tears With and Without Augmentation With a Bio-Inductive Collagen Implant Reveals Substantial and Comparable Clinical Improvement.

Purpose: To compare clinical and imaging results after repair of retracted large and massive full-thickness rotator cuff tears, including revision repairs, with and without augmentation with a bio-inductive collagen implant.

Methods: The study group comprised 24 patients (17 male subjects) with retracted 2 or 3 tendon rotator cuff tears undergoing arthroscopic repair followed by onlay augmentation with a bio-inductive collagen implant. The control group comprised 24 patients (19 male subjects) matched by tear size undergoing repair without augmentation.

Total shoulder arthroplasty in patients aged 80 years and older: a systematic review.

Background: Elderly patients and their surgeons may eschew shoulder arthroplasty due to concerns over patient safety and longevity. The purpose of this study was to review the current literature evaluating the clinical and radiographic outcomes of shoulder arthroplasty performed in patients 80 years and older.

Methods: A literature search of the Embase, PubMed, Medline, and Cochrane databases was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

Conjoining Trees for the Provision of Living Architecture in Future Cities: A Long-Term Inosculation Study.

Faced with the environmental challenges posed by climate change, architects are creating nature-based solutions for urban areas, such as transforming living trees into artificial architectural structures. In this study, we have analyzed stem pairs of five tree species conjoined for more than eight years by measuring the stem diameters below and above the resulting inosculation and by calculating the respective diameter ratio. Our statistical analyses reveal that × and stems do not differ significantly in diameter below inosculation.
