Comparison of the Quadriceps Muscle Thickness and Function between Patients with Patellofemoral Pain Syndrome and Healthy Subjects using Ultrasonography: An Observational Study.

Objectives: To compare the thickness and function of the quadriceps muscle in subjects with and without patellofemoral pain syndrome (PFPS) by ultrasonography.

Methods: Patients diagnosed with PFPS were included in the study. To measure the thickness of the rectus femoris (RF), vastus medialis longus and oblique (VML, VMO), vastus lateralis (VL) and vastus intermedius (VI), the ultrasonography was employed in rest and normal contraction modes and also the % rest-thickness normal as muscle function.

Peroneus Longus Tendon Autograft versus Hamstring Tendon Autograft in Anterior Cruciate Ligament Reconstruction: A Comparative Study with a Mean Follow-up of Two Years.

Background: Peroneus longus tendon can be a suitable alternative autograft for anterior cruciate ligament reconstruction (ACLR). The present study aimed to compare the clinical outcome and donor site morbidity in ACLR using peroneus longus tendon autograft versus hamstring tendon autograft.

Methods: In a comparative cross-sectional study, ACLR was performed with quadrupled hamstring tendon autograft in 65 patients between 2017 and 2018, and in another group, peroneus longus tendon autograft was used for ACLR in 65 patients between 2018 and 2019.

Repair of popliteomeniscal fascicles tear using a posterior transseptal portal fixes hypermobile lateral meniscus.

Purpose: This study investigates the effects of the all-inside repair of posterosuperior popliteomeniscal fascicle (PMF) on lateral meniscus stabilization using a posterior arthroscopic approach.

Methods: Between 2015 and 2018, 17 patients with hypermobile lateral meniscus (HLM) underwent posterior knee arthroscopy for PMF repair. The all-inside repair was performed through posteromedial transseptal and posterolateral portals using a suture hook technique.

Posterior knee arthroscopy facilitates the safe and effective all-inside repair of locked bucket-handle medial meniscal tear using a suture hook technique.

Purpose: This study reported the outcomes of locked bucket-handle medial meniscal tear (BHMMT) repairs using an arthroscopic posterior approach during anterior cruciate ligament (ACL) reconstruction.

Methods: Between 2011 and 2014, 48 patients with BHMMTs and ACL tears who met the eligibility criteria were enrolled in the present study. BHMMTs were assessed using a posterolateral transseptal portal and repaired using a posteromedial portal.

Treatment of Posterior Cruciate Ligament Tibial Avulsion: A New Modified Open Direct Lateral Posterior Approach.

The optimal operative technique for the treatment of the tibial-side avulsion injuries of the posterior cruciate ligament (PCL) is debatable. This study was aimed to evaluate the postoperative outcomes and complications if any after an open direct, posterolateral approach using cannulated cancellous screw fixation of a PCL tibial avulsion. From January 2016 to June 2018, 17 patients (14 males and 3 females) with PCL avulsion fraction treatment-who underwent open reduction and internal fixation using cannulated cancellous screws-were included in this prospective study.

Autogenous Osteochondral Grafting for Treatment of Knee Osteochondritis Dissecans: A Case Series Study.

Background: Although some surgical techniques have been described for the operative treatment of unstable Osteochondritis dissecans (OCD) of the knee, outcomes are variable and are not satisfying totally. The aim of the present study is to evaluate the outcomes of autogenous osteochondral grafting for OCD of the knee.

Methods: In a case series study, from June 2014 to July 2015, 16 patients with stage II-IV OCD (International Cartilage Repair Society (ICRS)) of the femoral condyle were investigated.

Revision Single-Stage Anterior Cruciate Ligament Reconstruction Using an Anterolateral Tibial Tunnel.

Revision anterior cruciate ligament (ACL) reconstruction is a technically demanding enterprise. Management of widened or previously malpositioned tunnels is challenging and often requires innovative approaches. The purpose of this study was to evaluate the function and clinical results of revision single-stage ACL surgery using an anterolateral tibial tunnel (ALTT).

Arthroscopic Treatment of Diffuse Pigmented Villonodular Synovitis of the Knee: Complete Synovectomy and Septum Removal-Midterm Results.

The purpose of this study was to evaluate and describe the clinical results of complete arthroscopic synovectomy through the four arthroscopic portals in the knees affected by diffuse pigmented villonodular synovitis (DPVNS). Between 2009 and 2012, 21 patients (15 men and 6 women) with the diffuse form of PVNS of the knee were enrolled in the study after qualification. The clinical diagnosis was confirmed by magnetic resonance imaging and postsurgical pathologic examination.

Arthroscopic all-inside ramp lesion repair using the posterolateral transseptal portal view.

Purpose: The purpose of this study was to evaluate and describe the clinical results and outcomes of a novel method for all-inside suture repair of medial meniscus ramp lesions through posteromedial and posterolateral transseptal portals during anterior cruciate ligament (ACL) reconstruction. Further, this investigation compared the posterolateral view to the notch view for diagnosis and repair.

Methods: Between 2011 and 2014, 166 patients had ramp lesions concomitantly with ACL injury; 128 patients (107 men and 21 women) were enrolled in the study after qualification.

Treatment Outcome of Intramedullary Fixation with a Locked Rigid Nail in Humeral Shaft Fractures.

Background: The aim of this study was to determine the treatment outcome of humeral shaft fractures with a locked rigid intramedullary nail in patients indicated for surgical treatment.

Methods: In this descriptive-cross sectional study, all patients were followed up for one, six, and 18 months post operatively. The Short Form Questionnaire (SF-36) and Constant Shoulder Score were applied.

A Case of Slipped Capital Femoral Epiphysis in Association With Craniopharyngioma.

Introduction: Slipped capital femoral epiphysis is characterized by the slippage of the proximal femoral epiphysis on the metaphysis, which is sometimes associated with an underlying endocrine disorder. Panhypopituitarism due to craniopharyngioma has been reported several times. We report a case of craniopharyngioma recurrence leading to slipped capital femoral epiphysis.

The effect of magnesium sulfate on motor and sensory axillary plexus blockade.

Background: Magnesium is a physiologic cation that blocks neuromuscular transmission and does not allow the nerve to be stimulated.

Objectives: This study investigates the effect of adding magnesium sulfate to lidocaine to extend the duration of sensory and motor blocks of the axillary plexus in orthopedic surgeries of the upper extremities.

Patients And Methods: This controlled randomized double-blind study was performed on patients who were candidates for orthopedic surgery of the upper extremities.

Survey of 2582 cases of acute orthopedic trauma.

Background: Orthopedic injuries are among the most common causes of mortality, morbidity, hospitalization, and economic burden in societies.

Objectives: In this research, we study the prevalence of different types of trauma requiring orthopedic surgery.

Patients And Methods: We conducted a cross-sectional study on 2582 patients with acute orthopedic injuries admitted to the orthopedic emergency ward at the Poursina Hospital (a referral center in Guilan province (northern Iran), during December 2010 through September 2011.
