The goal of this study was to evaluate the complications and efficacy of total joint arthroplasty in the extremely elderly and compare the survival with the normal age-matched population. One hundred one joint arthroplasties (45 total knee arthroplasties [TKAs], 56 total hip arthroplasties [THAs]) were performed in 83 patients 89 years old and older. Over an average follow-up period of 2.5 years, 26 (31%) of the patients died. Three patients (3.6%) died within the first 2 months' postoperatively. The perioperative medical complication rate (excluding deaths) was 14%. Significant improvements were noted in pain scores, Harris Hip Scores, and Knee Society Scores. The survival of patients in their nineties who undergo total joint arthroplasty is at least equal to the survival of an age-matched population for 2.5 years following surgery. With careful patient selection and patient care to minimize medical complications, total joint arthroplasty can be an excellent option for patients who are age 89 and older.

A bibliometric analysis of the 50 most cited articles on acromioclavicular joint reconstruction.
Musculoskelet Surg
January 2025
Graduate Entry Medical School, University of Limerick, Co. Limerick, Republic of Ireland.
The aim is to identify the 50 most cited papers and thus the most influential papers pertaining to ACJ reconstruction, and specifically, analysing the level of evidence (LOE), article content, journals occurring, and countries represented within the 50 most cited. A search of the Web of Science database was carried out using the following terms: "Acromioclavicular joint" OR "AC joint" (Topic) AND Reconstruction OR Repair (Topic). The top 50 relevant articles were analysed in relation to citations, citation density, geographic origin of the article, year published, and article type.

Introduction: Inter-set rest intervals are essential to reduce muscle fatigue and increase the total amount of volume of resistance training. Static stretching and walking may increase muscle blood flow and promote recovery during inter-set rest intervals. Therefore, the purpose of this study was to investigate the effects of 20 seconds of static stretching and walking during inter-set rest intervals of leg extension exercises on the number of repetitions to exhaustion, total amount of volume, and flexibility of the quadriceps (joint range of motion and muscle hardness) in untrained healthy males.

Background: Previous studies have shown that dyslipidemia is significantly associated with primary frozen shoulder and may be a risk factor for the development of primary frozen shoulder. However, these findings may be biased by a number of confounding factors. We investigated the association between serum lipids and primary frozen shoulder by retrospective analysis and two-sample Mendelian randomization (MR) methods.

Introduction: Total and sub-total lesions of the anterior cruciate ligament (ACL) are one of the most frequent and performance-limiting injuries to the knee joint within the active population. Early surgical management, often regarded as the primary management strategy, has recently been shown to have similar outcomes when compared with an initial rehabilitative approach followed by surgical ACL reconstruction if higher levels of functionality are needed. The primary objective of the study was to investigate the physiotherapists and orthopedic surgeons' "coper/non-coper" screening application in the clinical management of the patient after ACL injury.

Introduction: Anterior knee pain and other patello-femoral (PF) complications frequently limit the success of total knee arthroplasty as the final treatment of end stage osteoarthritis. However, knowledge about the loading conditions at the PF joint remains limited, as no direct measurements are available. We hypothesised that the external knee flexion moment (EFM) is highly predictive of the PF contact forces during activities with substantial flexion of the loaded knee.
