[Total hip arthroplasty secondary to ocronotic arthropathy. A case report].

Introduction: alkaptonuria is a rare hereditary metabolic disorder which is characterized by deficiency of the enzyme homogentisate 1,2 dioxygenase, which is responsible for the oxidation and renal elimination of homogentisic acid (HGA), which causes its accumulation. The excessive accumulation of HGA results in ochronosis and ochronotic arthropathy, which mainly affects the thoracolumbar spine and the large joints, leading to the need for joint replacement seeking to improve function and quality of life.

Clinical Case: hereby is presented a 67-years-old female patient with history of alkaptonuria with diffuse painful right hip of 4 years of evolution.

Traumatic and Atraumatic Rotator Cuff Tears Have the Same Rates of Healing.

Background: To examine whether traumatic rotator cuff repairs (RCRs) differ in postoperative rotator cuff tendon integrity and functional outcomes from degenerative RCRs.

Methods: RCRs performed by a single surgeon were retrospectively identified. The inclusion criteria were repairable Goutallier grades 0 to 2 full-thickness rotator cuff tears.

All-Arthroscopic Management of Locked Posterior Shoulder Dislocation: Reduction Under Direct Visualization and Treatment of Intra-articular Pathologies.

Locked posterior shoulder dislocation (LPSD) is a rare condition often overlooked. In most cases, the humeral head remains stuck behind the glenoid, causing an impression fracture in 40% to 90% of LPSD cases, known as a reverse Hill-Sachs lesion. The condition also affects the posterior capsulolabral complex and leads to the formation of scar tissue under the coracoid and subscapularis tendon, making it challenging to reduce without surgery.

[Results of all-inside arthroscopic meniscal sutures, mid-term review].

Introduction: all-in meniscal suture devices have evolved and simplified meniscal repair. In this study we will formulate the following research questions: what is the rate of survival and failure? What are the risk factors associated with failure? And what are the functional results after meniscal repair surgery?

Material And Methods: ambispective study from 2001 to 2021 of patients with repairable meniscal injury with all-in meniscal suture devices. The survival and failure ratio were obtained with the Kaplan-Meier test, the risk factors associated with meniscal suture failure were assessed with the logistic regression test, and the pre- and post-surgical functional results were estimated with the test.

[Effect of tibial slope on functional recovery in patients undergoing anterior cruciate ligament reconstruction].

Introduction: the tibial slope has been identified as one of the factors associated with graft failure after anterior cruciate ligament (ACL) reconstruction; however, its relationship with functional results has been little studied. The main purpose of this study is to determine the effect of the tibial slope on functional recovery in patients undergoing reconstruction of the anterior cruciate ligament.

Material And Methods: we included patients with a diagnosis of anterior cruciate ligament injury undergoing primary reconstruction, from May 2018 to May 2019, who had a complete radiographic and clinical record; also, the scores from questionnaires of the International Knee Documentation Committee (IKDC) and Lysholm scores were collected pre surgical procedures and throughout the one-year follow-up.
