Editorial Commentary: Superior Capsular Reconstruction Is the Treatment of Choice for Massive, Irreparable Rotator Cuff Tears With Pseudoparalysis.

The ideal treatment approach to massive, irreparable rotator cuff tears remains a hot topic of debate. In addition to joint-preserving methods including partial repair and subacromial spacer, techniques such as superior capsular reconstruction and tendon transfers are viable alternatives. These techniques are effective in providing pain relief and-to an extent-functionality during short-term follow-up; however, superior capsular reconstruction (SCR) appears to be the treatment of choice to address the pseudoparalysis.

An anatomo-functional implant positioning technique with robotic assistance for primary TKA allows the restoration of the native knee alignment and a natural functional ligament pattern, with a faster recovery at 6 months compared to an adjusted mechanical technique.

Purpose: An anatomo-functional implant positioning (AFIP) technique in total knee arthroplasty (TKA) could restore physiological ligament balance (symmetric gap in extension, asymmetric gap in flexion). The purposes were to compare (1) ligament balancing in extension and flexion after TKA in the AFIP group, (2) TKA alignment, implant positioning and patellar tracking between AFIP and adjusted mechanical alignment (aMA) techniques, (3) clinical outcomes between both groups at 12 months.

Methods: All robotic-assisted TKA with an AFIP technique were included (n = 40).

Humeral head cysts: association with rotator cuff tears and age.

The objective of this study was to retrospectively evaluate the prevalence of the cystic changes at rotator cuff footprint on proximal humeral tuberosities and investigate their relationship with rotator cuff tears and patient age. Magnetic resonance (MR) images of 657 patients who underwent shoulder arthroscopy for treatment of rotator cuff disorders were reviewed to localize the cystic changes at anterior (supraspinatus insertion) and posterior (infraspinatus insertion) aspects of greater tuberosity (GT) and lesser tuberosity (subscapularis insertion). Preoperative MR reports as well as cyst size and locations on MR images were correlated with arthroscopic records of rotator cuff pathology (tear type, size, location and tendon involvement) and patient age.

Heterotopic ossification in portal sites following hip arthroscopy.

Heterotopic ossification (HO) is a well-known condition that usually occurs after head trauma, burns and open surgical procedures, most commonly around the hip and elbow joints. It is a well-documented complication occurring after open hip surgery; however, there exists limited information regarding its prevalence and clinical importance following hip arthroscopy. We report a case of symptomatic HO formation in portal sites following arthroscopic rim decompression, femoroplasty and labral debridement that was successfully treated with arthroscopic removal.

The role of radiological subacromial distance measurements in the subacromial impingement syndrome.

Subacromial impingement is one of the most common causes of painful shoulder in the middle aged and elderly population. Since Neer's first description of the process, many investigators have researched this condition in an effort to gain a better understanding of the disease etiology. The aim of this study was to investigate the relationship between the radiological subacromial distance measurements and the subacromial impingement syndrome in a series of patients from our institution.

The treatment of segmental bone defects in rabbit tibiae with vascular endothelial growth factor (VEGF)-loaded gelatin/hydroxyapatite "cryogel" scaffold.

An experimental nonunion model was established by creating critical-sized (10 mm. in length) bone defects in the proximal tibiae of 30 skeletally mature New Zealand white rabbits.

Arthroscopic repair of type II superior labrum anterior posterior (SLAP) lesions in patients over the age of 45 years: a prospective study.

Background: Superior labrum anterior posterior (SLAP) lesions are a well-defined cause of shoulder pain and disability and may occur in conjunction with rotator cuff tears. This study was designed to prospectively evaluate the minimum 2 year results of arthroscopic repair of type II SLAP lesions in patients over the age of 45 years with and without rotator cuff tears.

Patients And Methods: Thirty-five patients with symptomatic type II SLAP lesions were enrolled in the study.

Intra-articular variations of the long head of the biceps tendon.

Purpose: The long head of the biceps tendon (LHBT) generally runs free through its course in the glenohumeral joint. It can rarely be seen as attached to the joint capsule or the rotator cuff in different patterns. Although these variations are usually considered harmless in the literature, they may occur in conjunction with the labral pathologies.
