Introduction: Historically, cementless patellar implants were fraught with issues of fixation and polyethylene wear. However, contemporary cementless patellar implants incorporate modern technologies for implant design and offer the potential for improved biological fixation and longevity. As such, an evaluation of the performance of modern cementless patellae is needed.

Article Synopsis
  • The study aimed to compare the Modular Dual Mobility (MDM) hip system and large femoral heads (LFHs) in revision total hip arthroplasties (THAs), focusing on risks like dislocation and metal-related complications.
  • Researchers analyzed 299 revision THAs and found that the MDM group had a significantly lower rate of re-revision for dislocation (99% survival) compared to the LFH group (91% survival), with increased risks for LFH patients.
  • Overall, THAs utilizing the MDM construct demonstrated a safer profile, particularly in reducing re-revisions related to dislocation and had no reported issues with metallosis or corrosion.

Article Synopsis
  • The study evaluated the reliability and accuracy of noninvasive hemoglobin (nHgb) monitoring compared to invasive serum hemoglobin (iHgb) tests in patients undergoing outpatient total joint arthroplasty (TJA).
  • The results showed that while both nHgb and iHgb values were similar post-surgery, the nHgb method had a significant advantage in terms of patient comfort and satisfaction, with 97% preferring it over the invasive method.
  • Additionally, the nHgb test effectively predicted low hemoglobin levels, suggesting it could be a viable alternative for monitoring in outpatient settings.

Article Synopsis
  • - The study investigates demographics and treatment outcomes of patients with periprosthetic joint infections (PJIs) in the hip and knee, highlighting that these infections are often under-reported and can be confused with culture contamination.
  • - A total of 35 PJIs were reviewed from January 2005 to December 2018, with findings indicating that about half were treated with chronic antibiotic suppression, while others underwent two-stage exchange arthroplasty; over two years, 94% remained free from revision.
  • - The results showed that PJIs typically exhibited laboratory characteristics similar to traditional organisms, and infections cultured more rapidly than expected; both chronic antibiotic treatment and surgical options had low failure rates at mid-term follow-up.

Aging is a major risk factor for osteoarthritis (OA), but the specific mechanisms connecting aging and OA remain unclear. Although chondrocytes rarely divide in adult articular cartilage, they undergo replicative senescence in vitro, offering a model to study aging-related changes under controlled conditions. OA cartilage was obtained from an 80-year-old male and a 72-year-old female, while normal cartilage was sourced from a 26-year-old male.
