A Modified Under-Vastus Approach for Knee Arthroplasty with Anatomical Repair of Soft Tissue.

A Modified Under-Vastus Approach for Knee Arthroplasty with Anatomical Repair of Soft Tissue. Clin Orthop Surg. 2019 Dec;11(4):490-494 Authors: Hiranaka T, Tanaka T, Fujishiro T, Anjiki K, Nagata N, Kitazawa D, Kotoura K, Okamoto K Abstract The under-vastus approach (UVA) is a modification of the conventional subvastus approach for knee arthroplasty. Our modified UVA allows the muscles to be spared while offering good exposure of the operative field and facilitating anatomical repair of the capsule and fascia. A medial parapatellar incision is made and the vastus medialis fascia is incised along the same line. The muscle belly is not incised but detached from the surrounding fascia and retracted laterally. The suprapatellar pouch capsule is then laterally incised under the vastus muscles. The patella can then be easily retracted laterally and adequate exposure is possible. After the procedure, both capsule and fascia can be anatomically repaired. We use this approach for all primary arthroplasties in our practice. There has been no case in which an additional muscle incision was required, and there were no intraoperative complications. The modified UVA allows for excellent exposure of the operative field as well as muscle retention in both primary total and unicompartmental knee arthroplasties. PMID: 31788174 [PubMed - in process]

This study evaluates parathyroidectomy outcomes in elderly patients.MethodsPrimary hyperparathyroidism patients having parathyroidectomy as listed in the 2005 –2017 ACS-NSQIP database were separated by age: ≤60, 61–79 and ≥80. Outcomes included complications, 30-day mortality, return to the OR, operating times, and hospital length of stay (LOS). Multivariable logistic regression was used to compare patients 61–79 and ≥80 to those ≤60. Patien ts ≤60 and ≥80 were propensity score matched using gender, race, BMI, smoking status, steroid use, modified frailty index (mFI), ASA class, procedur...

It is now becoming routine to test for germline mutations in the BRCA1 and BRCA2 genes, which are responsible for a significant proportion of hereditary epithelial ovarian cancer and are established predictive biomarkers of potential benefit ...

oal Dooly In recent years, we have seen significant interest in the use of permanently deployed resident robotic vehicles for commercial inspection, maintenance and repair (IMR) activities. This paper presents a concept and demonstration, through offshore trials, of a low-cost, low-maintenance, navigational marker that can eliminate drift in vehicle INS solution when the vehicle is close to the IMR target. The subsea localisation marker system is fixed on location on the resident field asset and is used in on-vehicle machine vision algorithms for pose estimation and facilitation of a high-resolution world coordinate...

CONCLUSIONS Anterior cruciate ligament suture with the InternalBrace ligament augmentation judging from the results achieved by our group of patients brings very good clinical outcomes already at 6 months postoperatively. This method allows the athletes to return to full load soon. It maintains the kinematics and knee joint proprioception, and thus can potentially contribute to the prevention of post-traumatic arthritis. Strict application of indication criteria is a precondition to success. A longer follow up and evaluation of a larger number of patients will, however, be necessary to definitely confirm the success of thi...

Abstract PURPOSE: To determine the efficacy of norbixin-based poly(hydroxybutyrate) (PHB) membranes for Achilles tendon repair. METHODS: Thirty rats were submitted to total tenotomy surgery of the right Achilles tendon and divided into two groups (control and membrane; n = 15 each), which were further subdivided into three subgroups (days 7, 14, and 21; n = 5 each). Samples were analyzed histologically. RESULTS: Histological analysis showed a significant reduction in inflammatory infiltrates on days 7, 14 (p

Purpose of review Optic neuropathies refer to a collection of diseases in which retinal ganglion cells (RGCs), the specialized neuron of the retina whose axons make up the optic nerve, are selectively damaged. Blindness secondary to optic neuropathies is irreversible as RGCs do not have the capacity for self-renewal and have a limited capacity for self-repair. Numerous strategies are being developed to either prevent further RGC degeneration or replace the cells that have degenerated. In this review, we aim to discuss known limitations to regeneration in central nervous system (CNS), followed by a discussion of previous,...
