A Randomized Controlled Trial Comparing "Early" Versus "Late" Periosteal Patch Attachment to Knee Chondral Defects in Autologous Chondrocyte Implantation.

Objective: Traditional autologous chondrocyte implantation (ACI) involves arthroscopically harvesting a cartilage biopsy (stage 1), followed by arthrotomy 3 to 4 weeks later to apply a periosteal patch and implant culture-expanded chondrocytes underneath (stage 2). This study aimed to determine if patch application during stage 1 rather than stage 2 improved clinical outcome.

Design: A randomized controlled trial was conducted from 1998 to 2001.

The impact of adjuvant antibiotic hydrogel application on the primary stability of uncemented hip stems.

Objectives: To assess the effect of adjuvant antibiotic-loaded hydrogel application on the primary stability of implanted uncemented hip stems.

Design: Biomechanical study.

Setting: An electro-mechanic material test system (#5866, Instron, Norwood, MA, USA) equipped with a 10-kN load cell was used.

Viscosupplementation with High Molecular Weight Hyaluronic Acid for Hip Osteoarthritis: a Systematic Review and Meta-Analysis of Randomised Control Trials of the Efficacy on Pain, Functional Disability, and the Occurrence of Adverse Events.

Purpose Of The Study: Hip osteoarthritis (OA) has a prevalence of around 6.4% and is the second most commonly affected joint. This review aims to assess the clinical outcomes of intra-articular high molecular weight hyaluronic acid (HMWHA) in the management of hip osteoarthritis.

The incidence and risk factors for abnormal postoperative blood tests following primary total joint replacement.

Aims: We aim to evaluate the usefulness of postoperative blood tests by investigating the incidence of abnormal results following total joint replacement (TJR), as well as identifying preoperative risk factors for abnormal blood test results postoperatively, especially pertaining to anaemia and acute kidney injury (AKI).

Methods: This is a retrospective cohort study of patients who had elective TJR between January and December 2019 at a tertiary centre. Data gathered included age at time of surgery, sex, BMI, American Society of Anesthesiologists (ASA) grade, preoperative and postoperative laboratory test results, haemoglobin (Hgb), white blood count (WBC), haematocrit (Hct), platelets (Plts), sodium (Na), potassium (K), creatinine (Cr), estimated glomerular filtration rate (eGFR), and Ferritin (ug/l).

Trochleoplasty for severe trochlear dysplasia significantly improves the quality of life of patients with symptomatic patellar instability.

Background: Trochleoplasty is a recognized surgical technique to address severe trochlear dysplasia. The clinical and radiological outcomes of trochleoplasty surgery in trochlear dysplasia have been well reported. There is a paucity in literature regarding the correlation between trochleoplasty and quality of life (QoL).
