AMIC achieves sustained clinical improvement in isolated patellar cartilage defects over 5 years, correlating with MRI.

Purpose: To evaluate 5-year postoperative clinical outcomes of autologous matrix-induced chondrogenesis (AMIC) for isolated ICRS grade 3-4 patellar cartilage defects and correlate outcomes with magnetic resonance imaging (MRI). The hypothesis was that AMIC would improve clinical symptoms and induce neocartilage formation, visible on MRI, making it a safe and effective option for repairing focal patellar cartilage defects.

Methods: The cohort comprised 13 focal patellar lesions in 12 patients.

Subchondroplasty® (SCP) Provides Resolution of Symptoms and Functional Improvements in Mild-to-Moderate Knee Osteoarthritis with Persistent Bone Marrow Lesions: 12-Month Follow-Up Results from a Multicentric Open-Label Prospective Clinical Trial.

Bone marrow lesions (BMLs) are MRI-visible subchondral bone alterations, highly correlated with symptoms in the knee. Subchondroplasty (SCP) is able to fill the subchondral defects associated with BMLs using an injectable bone substitute material. The aim of the present study is to evaluate the 12-month outcomes of the SCP in the treatment of symptoms of mild-to-moderate knee osteoarthritis (OA) patients with persistent BMLs of the knee.

Predictors of outcomes after internal fixation of periprosthetic femoral hip fractures Subgroup analysis of the peri-implant and peri-prosthetic fractures Spanish registry (PIPPAS).

Purpose: To identify risk factors predisposing patients to poor outcomes after fixation of periprosthetic hip fractures around femoral stems.

Methods: Prospective multicentre cohort study of fractures around a hip replacement stem managed by internal fixation. The primary outcome was one-year mortality, while secondary outcomes were local complications and healthcare burden-related outcomes (nursing facility utilization and hospital length of stay).

Temporary immobilization methods for closed low-energy ankle fracture-dislocations: comparative analysis of a retrospective cohort.

Purpose: Ankle fracture-dislocations (AFD) often necessitate staged management involving temporary external fixation (EF) due to mechanical instability or blistering. However, limited literature exists on the optimal temporary immobilization method for low-energy closed AFD. This study compared baseline patient and fracture characteristics, along with clinical and radiological outcomes between AFD initially immobilized with EF versus splinting.

Multiligament knee injuries. Ten years' experience at a public university, level I Trauma Center.

Purpose: To describe our institutional experience and results in the surgical management of multiligament knee injuries (MLKI).

Materials And Methods: Retrospective series of MLKI consecutively operated on at a single, level I Trauma Center. Data on patients' baseline characteristics, injuries, treatments, and outcomes were recorded up to one-year follow-up.

Good rates of return-to-sport in athletes after revision anterior cruciate ligament reconstruction using autologous patellar tendon and lateral extra-articular tenodesis: a 2-year follow-up prospective study.

Background: Most athletes who undergo revision of the anterior cruciate ligament reconstruction (ACLR) aim to return to their preinjury sport at a similar level of performance while minimizing the risk for reinjury. Additional lateral extra-articular tenodesis (LET) has recently been correlated with improved outcomes and low complication rate. Yet, there are few series evaluating return-to-sport (RTS) and clinical outcomes after revision ACLR using bone-patellar tendon-bone (BPTB) and LET in athletes.

Allografts and lateral extra-articular tenodesis for revision anterior cruciate ligament reconstruction: enhanced rotational stability and improved functional outcomes.

Purpose: Multiple studies have shown higher failure rate and patient-reported outcomes to be significantly worse following revision anterior cruciate ligament reconstructive (ACLR) surgery, especially using allografts. One of the reasons being rotational instability. Because of this, augmentation with lateral extra-articular tenodesis (LET) is often considered.

Usefulness of PCR Screening in the Initial Triage of Trauma Patients During COVID-19 Pandemic.

Background: Hospitals worldwide have postponed all nonessential surgery during the COVID-19 pandemic, but non-COVID-19 patients are still in urgent need of care. Uncertainty about a patient's COVID-19 status risks infecting health care workers and non-COVID-19 inpatients. We evaluated the use of quantitative reverse transcription polymerase chain reaction (RT-qPCR) screening for COVID-19 on admission for all patients with fractures.

Risk factors for symptomatic retears after arthroscopic repair of full-thickness rotator cuff tears.

Background: Factors affecting a rotator cuff symptomatic retear after arthroscopic repair have yet to be clearly identified, since they usually influence the surgical decisions.

Methods: Consecutive patients with full-thickness tear of the supraspinatus who underwent arthroscopic repair were retrospectively analyzed. Cases of symptomatic retear, defined as Sugaya type IV and V on magnetic resonance imaging, associated with intensive pain and/or functional impairment were identified at follow-up.

Large fracture of the anteromedial tibial plateau with isolated posterolateral knee corner injury: case series of an often missed unusual injury pattern.

Tibial plateau fractures are a heterogeneous group of lesions with multiple fracture patterns. They are often associated with soft tissue injuries, the lateral meniscus and the anterior cruciate ligament (ACL) being the most common structures affected. The purpose of this article is to present a case series of an often missed unusual injury pattern that consists on the association of a large anteromedial tibial plateau fracture with a posterolateral (PL) knee corner injury without involvement of the cruciate ligaments.

Wrist synovial chondromatosis: case report and literature review.

Primary synovial chondromatosis is a proliferation of cartilaginous bodies within the synovial membrane, tendon sheath or bursa. It is a rare orthopaedic entity especially when it occurs in the distal radioulnar joint. We report a 27-year-old man with recurrent synovial chondromatosis, nine years after his first operation.
