Article Synopsis
- * Conducted as a double-blind, randomized controlled trial with 86 TKA patients, results showed that the DXM group experienced significantly less pain and fewer vomiting episodes compared to the placebo group, alongside improved mobility and muscle strength.
- * The findings concluded that a single preoperative dose of dexamethasone is safe and effective for managing pain post-TKA, with no reported wound complications during the follow-up period. *
Article Synopsis
- The study evaluated the outcomes of using low-cost hook plates made from titanium mini plates for fixing mallet fractures, aiming to prevent complications like extension lag and arthritis.
- In a case series of 17 patients, mainly males with an average age of 32.3, surgeries were performed with an average duration of about 37.65 minutes, and follow-up lasted around 11 months.
- Results showed varying degrees of success, with 35.3% of patients rated as excellent, while 35.29% experienced complications, indicating the technique provides stable fixation and allows early movement but has some risks.
Background: The aim of this magnetic resonance imaging (MRI) study was to investigate controversial sexual dimorphism of the posterior condylar offset of the femur (the offset) and the posterior slope of the tibia (the slope) in non-arthritic knees of Egyptian adults.
Methods: On 100 male and 100 female MRIs of non-arthritic knees, linear measurements of the distal part of the femur (the offset) and the angular measurements of the proximal part of the tibia (the slope) were performed and compared regarding sex and ethnicity. The intraclass correlation coefficient (ICC) was used to test the interrater agreement.
Purpose: To predict the most important preoperative factor affecting the patient satisfaction after total knee arthroplasty (TKA) in trial to improve patient counselling process.
Methods: We retrospectively reviewed all patients who underwent primary TKA from January 1, 2018, to January 31, 2019, with minimum one-year follow-up for the previously collected patient-reported outcome measures (PROMs) as Oxford Knee Score (OKS) and Knee Injury and Osteoarthritis Outcome Score for joint replacement (KOOS, JR) preoperative, 6 months and 12 months postoperative.
Results: By using Oxford knee score at 12 months as dependent variable, we found a negative moderate spearman correlation between age and Oxford knee score at 12 months postoperative.
Background: Anterior closing wedge osteotomies (ACWO) are performed in revision anterior cruciate ligament (ACL) surgery to correct an excessive posterior tibial slope (PTS).
Purpose: With the help of automated planning software, this study investigates the assumption that 1mm of wedge height gives 1° of slope correction (1:1).
Methods: Fifty patients underwent ACWO, with the wedge height calculated using the 1:1 formula.

Purpose: To compare the clinical and radiological outcomes of patient-specific instrumentation (PSI) with the conventional free hand (FH) technique in performing coronal plane corrective knee osteotomies in terms of limb alignment and functional scores. The hypothesis is that conventional FH technique in experienced hands with proper pre-operative planning is as precise as PSI.
Methods: Patients who underwent coronal plane corrective knee osteotomies with either PSI or FH technique between 2017 and 2019 by the same senior surgeon and have a minimum of 2 years follow-up period were included in this study.
Early periprosthetic joint infection in unicompartmental knee arthroplasty (UKA) is shown to have a detrimental effect on the success of UKA surgery not only because of the sequences of the infection but also due to the other healthy lateral compartment. It is well known that Oxford meniscal bearing UKA is a very precise procedure that the use of any excessive force may have an injurious effect on the future prosthesis stability with a higher risk of bearing dislocation. This technical note aims at describing how to deal with a case of early periprosthetic joint infection in a female patient who underwent debridement, wash, implant retention and change of the mobile bearing insert including the demonstration of a difficult step during this procedure.

The primary aim was to investigate the Egyptian knees' anthropometric characteristics as a representative of North African populations. Secondary aims are as follows: (1) to study the anthropometric gender difference, (2) to compare results with other ethnic groups, and (3) to study the mismatch in comparison to geometric characteristics of modern TKA implant designs.
