Mortality rates reported by the National Joint Registry for England
and Wales (NJR) were higher following cemented total knee replacement
(TKR) compared with uncemented procedures. The aim of this study
is to examine and compare the effects of cemented and uncemented
TKR on the activation of selected markers of inflammation, endothelium,
and coagulation, and on the activation of selected cytokines involved
in the various aspects of the systemic response following surgery. This was a single centre, prospective, case-control study. Following
enrolment, blood samples were taken pre-operatively, and further
samples were collected at day one and day seven post-operatively.
One patient in the cemented group developed a deep-vein thrombosis
confirmed on ultrasonography and was excluded, leaving 19 patients

Methods
Single-shot adductor canal block (ACB) after total knee arthroplasty (TKA) for postoperative analgesia is a common modality. Patients can experience breakthrough pain when the effect of ACB wears off. Local anaesthetic infusion through an intra-articular catheter (IAC) can help manage breakthrough pain after TKA. We hypothesized that combined ACB with ropivacaine infusion through IAC is associated with better pain relief compared to ACB used alone. This study was a prospective double-blinded placebo-controlled randomized controlled trial to compare the efficacy of combined ACB+ IAC-ropivacaine infusion (study group, n = 68) versus single-shot ACB+ intra-articular normal saline placebo (control group, n = 66) after primary TKA. The primary outcome was assessment of pain, using the visual analogue scale (VAS) recorded at 6, 12, 24, and 48 hours after surgery. Secondary outcomes included active knee ROM 48 hours after surgery and additional requirement of analgesia for breakthrough pain.Aims
Methods
The goal of this study was to determine whether intra-articular
administration of the potentially anti-fibrotic agent decorin influences
the expression of genes involved in the fibrotic cascade, and ultimately
leads to less contracture, in an animal model. A total of 18 rabbits underwent an operation on their right knees
to form contractures. Six limbs in group 1 received four intra-articular
injections of decorin; six limbs in group 2 received four intra-articular
injections of bovine serum albumin (BSA) over eight days; six limbs
in group 3 received no injections. The contracted limbs of rabbits
in group 1 were biomechanically and genetically compared with the
contracted limbs of rabbits in groups 2 and 3, with the use of a
calibrated joint measuring device and custom microarray, respectively.Objectives
