Purpose Periprosthetic joint infection (PJI) is one of the most dreaded and challenging complications after total joint arthroplasty (TJA). The aim of this study was to evaluate the effect of keeping the dressing without change on the occurrence of PJI in patients undergoing TJA. Methods 4877 Patients with a minimum follow-up of 90 days were included to investigate the effect of dressing on the PJI occurring within 3 months of surgery. Patients were divided into two consecutive groups as the intermittent change of traditional dressing (group 1-before 2019) and keeping dressing for 5 days without change (group 2-after 2019). A backward stepwise logistic regression model was used to estimate independent risk factors for PJI. Results Group 1 and group 2 consisted of 4172 and 705 patients, and the numbers of diagnosed PJI cases in the groups were 40 (1.0%) and 10 (1.4%), respectively (p = 0.1). The backward stepwise logistic regression model analysis revealed that keeping the dressing unchanged and removing it after the first week postoperatively was not an independent risk factor for the occurrence of PJI. Older age, diabetes mellitus and coronary artery diseases were independent risk factors for PJI (p < 0.05). Conclusion Our study results present, that intermittent change of conventional dressing is unnecessary, because it does not decrease the risk of PJI after TJA.

Background: We hypothesized that a rectangular cross-sectional femoral stem may produce more initial stability of the transverse subtrochanteric femoral shortening osteotomy rather than a circular cross-sectional stem.

Objective: The aim of this experimental study was to evaluate and compare the chondroprotective efficacy of intra-articular hyaluronic acid, tenoxicam and vitamin E in osteoarthritis. Methods: An osteoarthritis model was created by anterior cruciate ligament transection and medial menisectomy in knees of 28 rats. The rats were randomized into four groups; first group served as a control group and received intra-articular injections of saline solution, intra-articular HA, intra-articular tenoxicam and intra-articular Vit E were applied to the treatment groups. First intra-articular injections were applied at second week postoperatively and repeated once a week for 5 weeks. At 8th week after the operation groups were compared based on the histologic scores of cartilage degeneration by Mankin Histological Grading Scale. Results: Total cartilage degeneration score was significantly increased in the control group (P=0.004). Total Mankin scores of HA, tenoxicam and Vit E groups were significantly lower than the control group (P=0.004, P=0.016, P=0.012 respectively). There was no statistically siginificant difference between the treatment groups in terms of total Mankin scores (P>0.05). Conclusion: Intra-articular application of HA, tenoxicam and Vit E are chondroprotective in early osteoarthritis model in rats. Chondroprotective activity of tenoxicam and Vit E are comparable with the beneficial effects of HA on articular cartilage.

The physical examination of the shoulder is usually not reliable for the true diagnosis of superior glenoid labrum anterior to posterior (SLAP) lesions. Magnetic resonance imaging (MRI) has been routinely used for the diagnosis. This prospective study investigates the radiological diagnosis of the SLAP lesions and compares accuracy of arthroscopic and MRI classifications.

Purpose This study was performed to compare short and standard-length tapered-wedge-type femoral stems in single-stage bilateral total hip arthroplasty (THA) through a direct anterior approach (DAA). Materials and methods The patients were divided into two groups according to their femoral stem types as short tapered-wedge stem and standard-length tapered-wedge stem groups. Outcome parameters were the surgical time, estimated blood loss (EBL), length of stay (LOS), thigh pain, Harris Hip Score (HHS), and visual analog scale (VAS) score clinically, and canal fill ratio (CFR), coronal plan alignment of the stems, subsidence, and postoperative leg length difference (LLD), radiologically. Results The short-stem group and standard-length-stem group consisted of 20 patients (40 hips, mean age 52.0 +/- 14.1) and 22 patients (44 hips, mean age 49.4 +/- 11.9), respectively. There were no significant differences between the groups in terms of mean surgical times (p = 0.6), EBL (p = 0.2), LOS (p = 0.2), the rate of thigh pain (p = 0.4), improvements in HHS (p = 0.4) and VAS scores (p = 0.6), LLD (p = 0.3), amount of subsidence (p = 0.9), and varus or valgus misalignment (p = 0.7). The CFR at the level of the lesser trochanter was significantly higher in the short-stem group (0.79 +/- 0.1) than the standard-length-stem group (0.73 +/- 0.1) (p < 0.01). Conclusion In single-stage bilateral THA through DAA, short, tapered-wedge femoral stems provide similar radiographic and functional results to standard stems at short-term follow-up.
