Adenosine, lidocaine, and Mg2+ (ALM) therapy exerts differential immuno-inflammatory responses in males and females early after anterior cruciate ligament (ACL) reconstruction (ACLR). Our aim was to investigate sex-specific effects of ALM therapy on joint tissue repair and recovery 28 days after surgery. Male (n = 21) and female (n = 21) adult Sprague-Dawley rats were randomly divided into ALM or Saline control treatment groups. Three days after ACL rupture, animals underwent ACLR. An ALM or saline intravenous infusion was commenced prior to skin incision, and continued for one hour. An intra-articular bolus of ALM or saline was also administered prior to skin closure. Animals were monitored to 28 days, and joint function, pain, inflammatory markers, histopathology, and tissue repair markers were assessed.Aims
Methods
To identify the early functional outcomes, survivorship and complications associated with the Corin Uniglide Unicompartmental Knee Replacement (UKRs) from an independent centre. A prospective consecutive case series of sixty Uniglide UKRs was carried out in fifty-one patients between January 2006 and March 2009. The data collected included:
Primary outcome measures: Pre- and post-operative American Knee Society Score (AKSS), Oxford Knee Scores (OKS), WOMAC Survivorship Secondary outcome measures: X-ray error scores assessing component position Complications No cases were lost to follow-up. Mean follow-up time was 19 months (12 to 36months) and mean age was 66 years (39 to 78 years). Kaplan-Meier Survivorship showed 95% survival at 3 years (CI:6.4). All functional outcomes showed significant improvement p <0.05. There were two revisions within the first year, which were the main complications, secondary to aseptic tibial loosening and collapse of the posteromedial tibia. The x-ray error score identified the most common error as the femoral flexion/extension angle followed by the anterior/posterior fit.Purpose of Study
Methods and Results
The traditional use of pneumatic tourniquets and reinfusion drains in total knee replacement (TKR) has recently been challenged and the aim of our study was to compare the outcomes of three different blood management techniques in primary TKR. We prospectively conducted a study of 87 patients with mean age of 71 (44-91) years old. They were randomised into three groups: Group A: 29 patients without the use of tourniquet and reinfusion drain, Group B: 27 patients without the use of tourniquet and reinfusion drain but application of intraoperative cell salvage system and Group C: 31 patients with the use of tourniquet and reinfusion drain. All groups were well matched and all patients were reassessed at the 2nd postoperative day.Purpose
Methods
This study aimed to evaluate the association between the sagittal alignment of the femoral component in total knee arthroplasty (TKA) and new Knee Society Score (2011KSS), under the hypothesis that outliers such as the excessive extended or flexed femoral component were related to worse clinical outcomes. A group of 156 knees (134 F:22 M) in 133 patients with a mean age 75.8 years (SD 6.4) who underwent TKA with the cruciate-substituting Bi-Surface Knee prosthesis were retrospectively enrolled. On lateral radiographs, γ angle (the angle between the distal femoral axis and the line perpendicular to the distal rear surface of the femoral component) was measured, and the patients were divided into four groups according to the γ angle. The 2011KSSs among groups were compared using the Kruskal-Wallis test. A secondary regression analysis was used to investigate the association between the 2011KSS and γ angle.Aims
