In-hospital length of stay (LOS) and discharge dispositions following arthroplasty could act as surrogate measures for improvement in patient pathways, and have major cost saving implications for healthcare providers. With the ever-growing adoption of robotic technology in arthroplasty, it is imperative to evaluate its impact on LOS. The objectives of this study were to compare LOS and discharge dispositions following robotic arm-assisted total knee arthroplasty (RO TKA) and unicompartmental arthroplasty (RO UKA) versus conventional technique (CO TKA and UKA). This large-scale, single-institution study included patients of any age undergoing primary TKA (n = 1,375) or UKA (n = 337) for any cause between May 2019 and January 2023. Data extracted included patient demographics, LOS, need for post anaesthesia care unit (PACU) admission, anaesthesia type, readmission within 30 days, and discharge dispositions. Univariate and multivariate logistic regression models were also employed to identify factors and patient characteristics related to delayed discharge.Aims
Methods
This study aimed to investigate time-dependent gene expression
of injured human anterior cruciate ligament (ACL), and to evaluate
the histological changes of the ACL remnant in terms of cellular
characterisation. Injured human ACL tissues were harvested from 105 patients undergoing
primary ACL reconstruction and divided into four phases based on
the period from injury to surgery. Phase I was <
three weeks,
phase II was three to eight weeks, phase III was eight to 20 weeks,
and phase IV was ≥ 21 weeks. Gene expressions of these tissues were
analysed in each phase by quantitative real-time polymerase chain
reaction using selected markers (collagen types 1 and 3, biglycan,
decorin, α-smooth muscle actin, IL-6, TGF-β1, MMP-1, MMP-2 and TIMP-1).
Immunohistochemical staining was also performed using primary antibodies
against CD68, CD55, Stat3 and phosphorylated-Stat3 (P-Stat3). Objectives
