Partial and complete repairs of massive rotator cuff tears maintain similar long-term improvements in clinical scores.

Purpose: The authors have previously published early outcomes of arthroscopic repairs of 86 massive rotator cuff tears (mRCTs) and aimed to determine whether their clinical scores are maintained or deteriorate after 5 more years.

Methods: Of the initial series of 86 shoulders, 2 had deceased, 16 lost to follow-up and 4 reoperated, leaving 64 for assessment. The repairs were complete in 44 and partial in 20, and 17 shoulders had pseudoparalysis.

Pre-operative templating in THA. Part II: a CT-based strategy to correct architectural hip deformities.

Introduction: Pre-operative templating for total hip arthroplasty (THA) remains inaccurate due to improper magnification and alignment. We aimed to describe an improved templating strategy using computed tomography (CT) to predict component sizes and offsets with greater accuracy.

Materials And Methods: We analysed 184 CT images acquired for pre-operative templating of primary THA.

Pre-operative planning in THA. Part III: do implant size prediction and offset restoration influence functional outcomes after THA?

Introduction: Few studies evaluated clinical benefits of pre-operative templating in total hip arthroplasty (THA). We investigated whether mismatch between planned and real implant sizes and medio-lateral offsets compromises THA outcomes.

Materials And Methods: We reviewed records of 184 primary THAs with pre-operative CT scans used for templating.

EUROVISCO Guidelines for the Design and Conduct of Clinical Trials Assessing the Disease-Modifying Effect of Knee Viscosupplementation.

Objectives: Hyaluronic acid viscosupplementation is a commonly used intra-articular treatment for osteoarthritis (OA). Some recent preclinical and clinical trials have demonstrated a potential for its disease-modifying effects. The goal of this expert opinion, consensus-driven exercise is to provide guidelines for the design and conduct of clinical trials assessing the disease-modifying effect of viscosupplementation in the knee.

Hidden degloving rotator cuff tears secondary to glenohumeral dislocation.

Background: A rare form of rotator cuff tear (RCT) is observed secondary to glenohumeral dislocation, followed by immediate repositioning, as well as formation of scar tissue between tendons and tuberosities. Radiographic diagnosis of such "degloving" tears is problematic because they are obscured by scar tissue. We aimed to describe characteristics of degloving tears and report outcomes following their arthroscopic repair.

Varus will have varus; a radiological study to assess and predict varus stem placement in uncemented femoral stems.

Background: Varus inclination of the uncemented stem is not necessarily a technical error. The proximal femoral anatomy of hips with a coxa vara deformity frequently predisposes varus inclination.

Methods: We reviewed a series of 200 patients undergoing primary uncemented THA with the Corail® hip system.

Influence of pre-operative tear size and tendon retraction on repair outcomes for isolated subscapularis tears.

Purpose: The purpose of this study was to investigate the influence of tendon tear size, in terms of length and retraction, on clinical and anatomic outcomes following repair for isolated subscapularis tears.

Methods: The records of 47 consecutive repairs of isolated subscapularis lesions were studied to correlate pre-operative tear characteristics with clinical and radiographic outcomes.

Results: Forty patients had complete radiographic outcomes at 3.

Should massive rotator cuff tears be reconstructed even when only partially repairable?

Purpose: (1) To evaluate midterm functional outcomes of arthroscopic repair of massive rotator cuff tears and (2) to determine the prognostic factors that could influence outcome. The hypothesis was that both partial and complete repairs would result in equivalent improvement of clinical score.

Methods: From a prospective series of 525 rotator cuff repairs, we analysed records of the 73 patients who were treated for massive tears.

Platelet-rich plasma as a treatment for chronic patellar tendinopathy: comparison of a single versus two consecutive injections.

Background: platelet-rich-plasma is increasingly used in chronic patellar tendinopathy. Ideal number of PRP injections needed is not yet established. This study compares the clinical outcomes of a single versus two consecutive PRP injections.

Evaluation of lengthening in reverse shoulder arthroplasty comparing X-rays and computerised tomography.

Purpose: The correct amount of arm lengthening in reverse shoulder arthroplasty is crucial to provide joint stability and good results. Determination has been proposed according to radiographs. However, radiographic measurements are error prone in regards to positioning of the arm with regard to the radiographic beam.

Posterolateral Bundle Reconstruction With Anteromedial Bundle Remnant Preservation in ACL Tears: Clinical and MRI Evaluation of 39 Patients With 24-Month Follow-up.

Background: Augmentation consisting of a selective reconstruction of the ruptured bundle while preserving the remnant bundle has been proposed as a treatment option for partial anterior cruciate ligament (ACL) tears. Good clinical outcomes after selective anteromedial (AM) bundle augmentation have been reported, whereas little is known about selective reconstruction of the posterolateral (PL) bundle with preservation of the AM bundle remnant.

Purpose: The purpose of this study was to evaluate the clinical outcomes and the magnetic resonance imaging (MRI) characteristics of selective PL bundle reconstruction with a median follow-up of 24 months.

Arthroscopic suture-bridge repair for small to medium size supraspinatus tear: healing rate and retear pattern.

Purpose: The purpose of the study was to assess the repair site integrity after transosseous equivalent/suture-bridge (TOE/SB) repair with the use of magnetic resonance imaging (MRI).

Methods: One hundred seven consecutive shoulders with a small to medium-size full-thickness supraspinatus tear were repaired arthroscopically with use of the TOE/SB technique. There were 64 men and 41 women, and mean age at the time of surgery was 54.

Clinical and structural results of arthroscopic repair of isolated subscapularis tear.

Background: Even though the frequency of arthroscopic repair of isolated lesions of the subscapularis tendon has increased, few studies have presented clinical and anatomical outcomes of this treatment. We hypothesized that, after an arthroscopic repair, structural outcomes in the muscle have an influence on functional results.

Methods: A retrospective study was performed on twenty-two patients who had undergone arthroscopic repair of an isolated tear of the subscapularis tendon and had a mean follow-up of thirty-six months.

Is the anterior tibial tuberosity a reliable rotational landmark for the tibial component in total knee arthroplasty?

To analyze the morphology of the tibial plateau, we studied 100 computed tomographic scans of arthritic knees and measured the mediolateral (ML) and anteroposterior (AP) dimensions as well as their aspect ratio using 3 reference axes of rotation: transepicondylar axis (TEA), posterior tibial margin (PTM), and anterior tibial tuberosity (ATT) axis. Relative to the TEA, the PTM was internally rotated by 1.6° ± 5.
