Patient-specific instrument for unicompartmental knee arthroplasty does not reduce the outliers in alignment or improve postoperative function: a meta-analysis and systematic review.

Arch Orthop Trauma Surg 2020 Apr 18. Epub 2020 Apr 18.

Department of Orthopaedic Surgery and National Clinical Research Center for Geriatrics, West China Hospital, Sichuan University, 37# Guoxue Road, Chengdu, 610041, Sichuan, People's Republic of China.

Background: Unsatisfactory alignment in unicompartmental knee arthroplasty (UKA) is one potential cause of postoperative failure. Patient-specific instruments (PSIs) are designed to improve the alignment of the prostheses, but the effect of PSIs on the alignment or clinical outcome is controversial and lacks validated evidence. We conducted a meta-analysis and systematic review to determine the effect of PSIs on UKA outcomes for the first time. Read More

Failure analysis of infection persistence after septic revision surgery: a checklist algorithm for risk factors in knee and hip arthroplasty.

Arch Orthop Trauma Surg 2020 Apr 15. Epub 2020 Apr 15.

Center for Musculoskeletal Surgery, Department of Orthopaedic Surgery, Charité-Universitaetsmedizin Berlin, Charitéplatz 1, 10117, Berlin, Germany.

Purpose: Several studies describe risk factors for primary periprosthetic joint infection (PJI) and general treatment outcome factors like microbe spectrum or patient-specific risk factors. However, these general and patient dependent findings cannot solely explain all cases of infection persistence after a prior septic revision. This study analyzes possible specific and patient independent reasons for failure after revisions for PJI in knee and hip arthroplasty. Read More

Is limited shoulder abduction associated with poor scapulothoracic mobility after reverse shoulder arthroplasty?

Arch Orthop Trauma Surg 2020 Apr 15. Epub 2020 Apr 15.

Shoulder and Elbow Surgery Department, Schulthess Clinic, Zürich, Switzerland.

Introduction: The contribution of the glenohumeral joint to shoulder abduction is acknowledged as an important factor for reverse total shoulder arthroplasty (RTSA) patients. In contrast, the degree of scapulothoracic joint contribution and its relation to RTSA patients with poor to excellent shoulder abduction are unclear.

Materials And Methods: Twenty-three selectively recruited patients (74 ± 7 years, 11 males) with shoulder abduction ranging from poor to excellent at least 6 months after primary, unilateral RTSA participated in this study. Read More
