tem is associated with better high-end function compared to standard implants.
We found that medial pivot system in primary total knee arthroplasty provide overall mid-term survivorship comparable to other standard implasnts. In addition, medial pivot system is associated with better high-end function compared to standard implants.The purpose of this study was to retrospectively assess patients treated with modular, non-cemented, tapered, fluted, distal fixation stems. We included patients with 24 months mínimum follow-up. Diagnosis that led to revisions were described. The radiographic analysis was made with preoperative, immediate postoperative and last control postoperative X-rays. Sixty-seven patients met inclusion criteria. We observed 59,7% (n=40) Osteointegration, 34,3% of Stable Fibrosis and 5,97% Unstable fibrosis. Stress Shielding was registered with 10,44% and Subsidence was observed in 34,3% of the patients. Modular, fluted, tapered, distal fixation stems have an excellent survival rates.
To evaluate the available evidence for the utility of Erector Spinae Plane blocks (ESPB) after Lumbar surgery.

Databases were searched until December 20, 2020. ESPB was utilized as a MesH term and terms such as lumbar spinal stenosis, spondylolisthesis, decompression and lumbar spine surgery.

Studies demonstrate that ESPB are consistently found to be a safe and effective method of analgesia after lumbar surgery, with limited adverse effects.

ESPB appear to be an effective method to relieve pain after lumbar surgery. More RCTs will be needed to further investigate the clinical effectiveness of this intervention.

This is a retrospective follow-up study of twelve patients who underwent CVOCA implantation from 2013 to 2015 by a single surgeon for a International Cartilage Repair Society (ICRS) grade 3 or 4 chondral defect. Patient-reported outcome (PRO) measurements and MRI were obtained 2-years postoperatively. Collected PRO measures included International Knee Documentation Committee (IKDC) form; Visual Analog Scale (VAS) pain score; Veterans RAND 12-Item Health Survey (VR-12); Knee Injury and Osteoarthritis Outcome Score (KOOS); and Western Ontario McMaster Universities Osteoarthritis Index (WOMAC). Patients completed a standard return to work and sports/recreation survey. A blinded, fellowship-trained musculoskeletal radiologist independently evaluated each MRI to determine the Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score. Mean follow-up was 2.1 years (2.0-2.3). There were 6 women and 6 men with a mean age of 46.2 ± 11.9 years. Mean PRO scores were IKDC 72.6 ± 17.4; VAS 2.9 ± 2.8; WOMAC 84.2 ± 15.1; KOOS- Pain 83.8 ± 18.5, Symptoms 77.6 ± 16.0, ADL 88.0 ± 16.9, Sports/Rec 67.7 ± 33.3, QOL 54.8 ± 24.2; and VR-12 PCS 45.0 ± 8.5 and MCS 51.1 ± 9.5. The mean MOCART score was 59.5 ± 12.9. To our knowledge, this is the largest study to report clinical and MRI outcomes of CVOCA implantation in the knee. With positive functional outcomes and lack of failures at 2-year follow-up, CVOCA is a promising treatment option for focal chondral defects in the knee.

The aim of our study was to evaluate whether an association exists between body mass index (BMI) category and post-operative opioid requirements among primary total joint arthroplasty (TJA) patients.

We retrospectively reviewed all primary unilateral total hip and total knee arthroplasty (THA/TKA, respectively) cases performed over a two-year period. We evaluated whether a relationship exists between five BMI categories (≤24.9, 25-29.9, 30-34.9, 35-39.9, ≥40) and morphine milligram equivalent (MME) use for total in-hospital, daily in-hospital, and total during six weeks post-discharge. Secondary outcomes included relationship with length of stay, discharge location, opioid refill rate, and pre-operative opioid usage.

For all patients undergoing primary TJA, increasing BMI resulted in an incremental increase in post-operative total in-hospital MME use for each successive BMI category when compared to those with BMI ≤24.9 (p<0.05). This association held true for the THA subset. Within the cohort as a whole, higher categories of BMI were associated with increased length of stay (35-39.9, ≥40), higher odds of needing a refill (30-34.9, 35-39.9, ≥40), and higher odds of discharging to a rehab facility (25-29.9, ≥40) (p<0.05). There was an increasing proportion of pre-operative opioid use as BMI category increased (p<0.0001).

BMI category is associated with increased in-hospital opioid requirements among primary TJA patients. Such findings are an important step to better understanding pain control expectations and can help facilitate development of opioid reduction strategies.

In doing so, we are often exposed to hazards that have the potential to not only compromise our health, but also our ability to deliver the best possible healthcare. Occupational hazards specific to the field of orthopaedics include infectious organisms, radiation, surgical smoke, chemicals, hazardous noise, musculoskeletal injury, and psychosocial stressors. Daidzein cost Even though orthopaedic surgeons acknowledge the risk, most lack in-depth knowledge of the associated long-term harm associated with these hazards and ways of reducing risk of exposure. Orthopaedic surgeons should increase awareness, follow established guidelines, and integrate preventative measures to create the safest possible work environment. It is our hope that by improving our own health, we will be better equipped to address the health concerns of those we serve-our patients.
