Review Meta AnalysisRisk factors for femoral stem fracture following total hip arthroplasty: a systematic review and meta analysis.
Femoral stem fracture following total hip arthroplasty (THA) is an infrequent but nevertheless devastating complication, with an increasing worldwide prevalence as demand for primary THA continues to increase. The aim of this study was to perform a systematic review and meta-analysis of risk factors for femoral stem fracture to help identify at risk patients. ⋯ This review concludes that patient weight, younger age, male sex, varus stem alignment, revision arthroplasty and use of modular stems are significant risk factors for femoral stem fracture. Modifying these risk factors where possible may help reduce incidence of femoral stem fracture in at risk patients.

Randomized Controlled Trial Multicenter StudyPerformance of medial pivot, posterior stabilized and rotating platform total knee arthroplasty based on anteroposterior stability and patient-reported outcome measures; a multicentre double-blinded randomized controlled trial of 210 knees.
Despite advancements in total knee arthroplasty (TKA), 10-20% of patients remain dissatisfied after surgery. Improved anteroposterior (AP) stability provided by medial pivot (MP) implants may theoretically lead to higher patient satisfaction. ⋯ MP-, PS- and RP-TKA all provide excellent and comparable results. Although MP-TKA provided better AP stability at early flexion compared to PS- and RP-TKA, this was found to be unrelated to improved PROMs in favour of MP-TKA. More studies focusing on early and mid-flexion performance based differences between MP and other TKA designs are required to confirm our findings. Other non-implant related factors may play a more important role in the performance of TKA and are potentially worthwhile examining.

Meta Analysis Comparative StudyComparison of revision rates and epidemiological data of a single total knee arthroplasty system of different designs (cruciate retaining, posterior stabilized, mobile bearing, and fixed bearing): a meta-analysis and systematic review of clinical trials and national arthroplasty registries.
This study aimed to meta-analyze epidemiological data, revision rates, and incidences of different designs of a single Total Knee Arthroplasty System and compare these factors across different countries. ⋯ In conclusion, pooled data from 41,200 cases of TKA with a single Total Knee Arthroplasty System in two arthroplasty registries revealed that there was no significant difference in revision rates between the mobile bearing and fixed bearing design within the first 5 years after implantation. In addition, a comparison of the revision rates in n = 123,361 cases showed no significant advantage for cruciate retaining or posterior stabilized in the first 5 years after implantation.

ReviewLocal antibiotic delivery via intra-articular catheter infusion for the treatment of periprosthetic joint infection: a systematic review.
There is an increasing interest in the use of intra-articular (IA) antibiotic infusion as a stand-alone or adjuvant therapy to standard revision surgery for periprosthetic joint infection (PJI). The objective of this systematic review is to evaluate the evidence with respect to this up-and-coming treatment modality. ⋯ Due to the lack of comparative studies the (added) benefit of IA antibiotic infusion in the treatment of PJI remains uncertain. Based on the current evidence, we would advise against using it as a stand-alone treatment. A prospective randomized controlled trial using a well-described infusion protocol is needed to see if the potential benefits justify the increased costs and potential complications of this treatment modality.

Meta Analysis Comparative StudyComparative analysis of surgical treatment modalities for a popliteal pterygium: a meta-analysis.
Popliteal pterygium syndrome is a rare congenital disorder characterized by orofacial, cutaneous, musculoskeletal, and genital anomalies. The popliteal pterygium (PP) affects ambulation due to severe knee flexion contracture and equinovarus deformities. Surgical treatment aims to correct these deformities while preserving limb sensibility. However, due to its rarity, surgical guidelines are lacking. ⋯ The management of PP demands a comprehensive approach, considering individual patient characteristics and treatment outcomes. While different surgical modalities offer distinct benefits, a classification or guideline to treat this deformity is still lacking. Further research is essential to validate findings, refine treatment approaches, and enhance the quality of life for individuals with PP.
