Determining the Minimal Clinically Important Difference on the Oxford Shoulder Instability Score in Patients Undergoing Arthroscopic Bankart Repair for Shoulder Instability.

Background: The literature on minimal clinically important differences (MCIDs) for patient-reported outcome measures assessing shoulder instability is limited, with none addressing the Oxford Shoulder Instability Score (OSIS). The OSIS was developed to provide a standardized method for assessing shoulder function after surgery for shoulder instability, and previous studies have demonstrated its high reliability, low interrater variability, and ease of administration.

Purpose: To identify the MCID for the OSIS after arthroscopic Bankart repair for recurrent shoulder instability.

What is the optimal surgical intervention for patients with frozen shoulder and a concomitant partial-thickness rotator cuff tear?

Background: Patients with recalcitrant frozen shoulder traditionally undergo arthroscopic capsular release. Some patients may have a concomitant partial-thickness rotator cuff tear (PTT). There is limited evidence if these PTT require repair at the same setting.

Subchondroplasty for Bone Marrow Lesions in the Arthritic Knee Results in Pain Relief and Improvement in Function.

Subchondroplasty is a relatively new joint preserving procedure, which involves the localized injection of calcium pyrophosphate bone substitute into the bone marrow lesion. The advent of magnetic resonance imaging (MRI) has greatly facilitated the identification of these bone marrow lesions. We investigated the clinical efficacy of subchondroplasty in the treatment of symptomatic bone marrow lesions in the knee, including knees with preexisting osteoarthritis.

Arthroscopic undersurface rotator cuff repair versus conventional arthroscopic double-row rotator cuff repair - Comparable results at 2-year follow-up.

Aim: The aim of our study is to compare the improvement in clinical outcomes after conventional arthroscopic double-row rotator cuff repair and arthroscopic undersurface rotator cuff repair.

Method: A consecutive series of 120 patients who underwent arthroscopic rotator cuff repair was analysed. Sixty-one patients underwent conventional double-row rotator cuff repair and 59 patients underwent undersurface rotator cuff repair.

Drain use in total knee arthroplasty is neither associated with a greater transfusion rate nor a longer hospital stay.

Purpose: In recent years, the exclusion of a drain in total knee arthroplasty (TKA) is gaining popularity. This retrospective study aims to investigate a tertiary hospital's experience with the use of a drain in TKA. The authors hypothesise that the use of a drain will: (1) increase the peri-operative total blood loss (TBL) and transfusion rate; (2) increase the length of hospital stay (LOS); (3) reduce the 30-day readmission rate and incidence of additional surgical procedure performed.
