Original surgical technique for the treatment of patellofemoral instability after failure of conservative treatment.

Introduction: Acute patellar dislocation is a common but serious injury that can significantly impact a patient's functional prognosis. The objective of this retrospective study is to evaluate the clinical outcomes of arthroscopic medial patellofemoral ligament (MPFL) reconstruction and plication of the medial patellar retinaculum using suture anchors in adolescent patients with first-time acute patellar dislocation (APD) and MPFL insertion injury.

Hypothesis: Tightening repair of the medial retinaculum complex can result in favorable clinical and functional outcomes in this patient population.

Functional results of modified Mason-Allen suture versus horizontal mattress suture in the arthroscopic Broström-Gould procedure for chronic ankle instability.

Background: The arthroscopic Broström-Gould procedure (ABG) gained particular attention among clinicians and researchers due to its high rate of satisfactory results. There is a lack of evidence regarding the differences in clinical outcomes for the various suture techniques. The purpose of this study was to compare the differences in clinical effect in patients treated with one-anchor modified Mason-Allen suture or two-anchor horizontal mattress suture for chronic ankle instability (CAI).

Large medial meniscus extrusion and varus are poor prognostic factors of arthroscopic partial meniscectomy for degenerative medial meniscus lesions.

Background: The indications and efficacy after arthroscopic partial meniscectomy (APM) for degenerative medial meniscus lesions (DMMLs) have been controversial. The purpose of this study was to identify predictors of unfavorable clinical and radiologic outcomes after APM for DMMLs and to choose appropriate indications and improve treatment efficacy.

Methods: A total of 86 patients with DMMLs undergoing APM were retrospectively reviewed.
