Outcomes of Trochleoplasty versus Tibial Tubercle Osteotomy for Treatment of Patellar Instability Associated with Trochlear Dysplasia: A Systematic Review and Meta-analysis.

This study compared the outcomes of tibial tubercle osteotomy (TTO) and trochleoplasty for the treatment of patellar instability associated with trochlear dysplasia. This was a systematic review of the literature including published articles that describe either trochleoplasty or TTO in addition to medial patellofemoral ligament reconstruction for the surgical treatment of patellar instability associated with trochleoplasty. Main outcomes assessed were Kujala and International Knee Documentation Committee (IKDC) scores, in addition to recurrent instability and complications.

Critical shoulder angle and acromial index do not influence functional outcomes after repair of massive rotator cuff tears.

Objectives: Critical shoulder angle (CSA) and acromial index (AI) are two radiographic signs that can influence the risk of rotator cuff tears and the outcomes of repair. The purpose of this study was to determine the influence of CSA and AI on massive cuff tears and on the functional outcomes after repair. The hypothesis was that CSA and AI would be higher in posterosuperior compared to anterosuperior tears.

Accuracy and Reliability of Computerized Surgical Planning Software in Anatomic Total Shoulder Arthroplasty.

Purpose: The primary purpose of this study was to assess the concordance between preoperatively determined implant parameters using CT-based planning software and surgically implanted prostheses. Secondarily, we sought to evaluate the agreement between preoperative plans performed by surgeons at different levels of training.

Methods: Patients with primary glenohumeral osteoarthritis who underwent anatomic total shoulder arthroplasty (aTSA) and had a preoperative CT scan according to Blueprint (Stryker, Mahwah, NJ) protocol to be used for preoperative planning were included.

Musculoskeletal Literacy in Orthopedics: Associated Factors, Effects on Patient-Physician Communication and Intervention Strategies.

Health literacy is defined as the degree to which an individual obtains and processes basic health information and services so as to make appropriate and informed health decisions. Limited health literacy (LHL), as assessed by various validated instruments, remains prevalent amongst older adult patients, non-Caucasian ethnicities, and those of lower socioeconomic backgrounds. Of concern, LHL has been associated with decreased medical knowledge, disuse of preventative medical services, worse chronic disease control and increased use of emergency services.

Lateralized versus nonlateralized reverse total shoulder arthroplasty.

Throughout the history of reverse total shoulder arthroplasty, the extent of lateral offset has changed considerably from "too lateral" to "too medial" and has been lately swinging back towards a point somewhere in between. Nonlateralized designs minimize shear forces on the glenoid and decrease force required by the deltoid. Glenoid lateralization decreases impingement and scapular notching and improves range of motion.

Novel repair of a quadriceps tendon rupture after a total knee arthroplasty using gracilis and semitendinosus autografts.

Background: Multiple techniques have been described for repair of quadriceps tendon rupture after total knee arthroplasty (TKA) with unsatisfactory outcomes. We present a novel technique for repair using hamstring tendon autografts.

Methods: A 54 year-old morbidly obese patient presented five months after quadriceps tendon rupture.

A decision analysis of treatment strategies for acute periprosthetic joint infection: Early irrigation and debridement versus delayed treatment based on organism.

Objective: The purpose of this study was to investigate whether immediate or delayed tailored DAIR treatment based on microbial species is the optimal treatment for acute post-operative periprosthetic joint infection (PJI).

Methods: A multicenter retrospective study was conducted to identify patients who underwent debridement, antibiotics, and implant retention (DAIR) for PJI. Decision analysis modeling was employed to determine the treatment strategy that yielded the greatest patient outcome.

Evaluation of callus formation in distal femur fractures after carbon fiber composite versus stainless steel plate fixation.

Introduction: Carbon-fiber-reinforced polyetheretherketone (CFR) composite plates have a more favorable stress modulus than stainless steel (SS) plates that may confer an advantage to bridge plating. The purpose of this study was to compare callus formation after CFR and SS plating of distal femur fractures.

Methods: A retrospective review identified distal femoral fractures treated with CFR (n = 10) and SS (n = 21) plate fixation.

Septic Arthritis following Arthroscopic Anterior Cruciate Ligament Reconstruction.

. We report two cases of () septic arthritis following arthroscopic anterior cruciate ligament (ACL) reconstruction. Both initial surgical procedures were ACL reconstruction along with simultaneous collateral ligament and meniscus procedures.

Outcomes of Reverse Total Shoulder Arthroplasty in Patients 60 Years of Age or Younger: A Systematic Review.

Purpose: Reverse total shoulder arthroplasty (RTSA) has been traditionally performed in elderly, low-demand patients. However, indications for RTSA are expanding, and patients who potentially benefit from this procedure are not restricted to those who are elderly. The purpose of this review was to summarize reported outcomes of RTSA in patients aged 60 years or younger.

Risk factors associated with ACL registry compliance: can we predict who will follow-up?

Purpose: The purpose of this study was to determine patient factors that influence patient compliance to fill out anterior cruciate ligament reconstruction (ACLR) registry forms.

Methods: Patients prospectively enrolled in the ACLR registry at a single institution were retrospectively reviewed. Patients who were followed up for at least 6 months were included.

Type 2 retear after arthroscopic single-row, double-row and suture bridge rotator cuff repair: a systematic review.

Aim/purpose: To provide a systematic review of the literature on patterns of retear after single-row (SR), double-row (DR) and suture bridge (SB) techniques.

Methods: The PubMed and MEDLINE databases were searched for published articles reporting both repair technique and retear pattern. Studies in languages other than English, those reporting open rotator cuff repair as the index procedure, as well as animal and cadaveric studies and those which did not describe patterns of retear, were excluded.

Patient factors influencing outpatient satisfaction in patients presenting with shoulder pain.

Background: Patient-based evaluation of health care has been gaining attention in the past 2 decades. The purpose of this study was to evaluate patient satisfaction in a shoulder outpatient clinic and determine which factors impact satisfaction levels.

Methods: Fifty-nine outpatients with shoulder complaints from December 2017 to January 2018 were included.

Recurrent tears of the rotator cuff: Effect of repair technique and management options.

Retears of the rotator cuff, following operative repair, is not an uncommon event. Various factors have been shown to influence recurrence including the technique of repair. Multiple techniques have been performed with varying results and complications.

Anatomic Medial Patellofemoral Ligament Reconstruction Without Bone Tunnels or Anchors in the Patella.

Medial patellofemoral ligament reconstruction is an essential component of surgical treatment for recurrent dislocation of the patella. Various techniques have been described, most of which potentially increase the risk of patellar fracture. We present a new technique for anatomic medial patellofemoral ligament reconstruction without using suture anchors or patellar tunnels, therefore, eliminating the risk of iatrogenic patellar fracture and making a revision procedure easier in case of failure.

Treatment of infection following intramedullary nailing of tibial shaft fractures-results of the ORS/ISFR expert group survey.

Objective: The lack of universally accepted treatment principles and protocols to manage infected intramedullary (IM) nails following tibial fractures continues to challenge us, eliciting a demand for clear guidelines. Our response to this problem was to create an ORS/ISFR taskforce to identify potential solutions and trends based on published evidence and practices globally.

Materials And Methods: A questionnaire of reported treatment methods was created based on a published meta-analysis on the topic.

Arthroscopic Management of SLAP Lesions With Concomitant Spinoglenoid Notch Ganglion Cysts: A Systematic Review Comparing Repair Alone to Repair With Decompression.

Purpose: To determine if cyst management is necessary in the setting of SLAP lesions with concomitant paralabral ganglion cysts.

Methods: We performed a systematic review according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, including all studies that met inclusion criteria from January 1975 to July 2015. We included patients with a SLAP II-VII lesion and a concomitant paralabral ganglion cyst who underwent arthroscopic labral repair with or without cyst decompression.

Reverse Segond Fracture Associated with Anteromedial Tibial Rim and Tibial Attachment of Anterior Cruciate Ligament Avulsion Fractures.

Reverse Segond fracture is an uncommon avulsion fracture of the tibial attachment of the deep portion of the medial collateral ligament of the knee. We report a reverse Segond fracture associated with anterior cruciate ligament tibial avulsion fracture and anteromedial tibial rim fracture. Unlike previous reports, the combination of reverse Segond fracture, anteromedial tibial rim fracture, and anterior cruciate ligament avulsion fracture was not associated with posterior cruciate ligament injury, posterolateral corner injury, or tibial plateau fracture.
