Objective: Autologous matrix-induced chondrogenesis (AMIC) is a 1-step cartilage restoration technique that combines microfracture with the use of an exogenous scaffold. This matrix covers and mechanically stabilizes the clot. There have been an increasing number of studies performed related to the AMIC technique and an update of its use and results is warranted. Design and methods: Using the P...

Purpose: The purpose of this study was to report the clinical outcomes of autologous chondrocyte implantation (ACI) procedures performed by a single orthopedic surgeon at a minimum of 7 years follow-up. Methods: A retrospective review of prospectively collected data was performed on 29 patients who underwent ACI of the knee between the years of 1998 and 2003. Prospective data were collected to ...

PURPOSE To determine clinical results after combined femoral osteochondral allograft and meniscus transplantation. METHODS Thirty-two patients with a minimum 2-year follow-up were identified who had previously undergone combined meniscus allograft transplantation and fresh osteochondral allograft transplantation. Demographic and intraoperative data, including condylar defect size, as well as ...

BACKGROUND Quadriceps tendon-patellar bone (QTPB) autograft is an excellent graft option with good clinical outcome. Use of QTPB autografts have increased because they minimize donor-site morbidity including anterior knee pain, while providing adequate mechanical strength. Although, there were many clinical results about allografts that used in anterior cruciate ligament (ACL) reconstruction, i...

Purpose High Outerbridge grade lesions of the articular cartilage have been associated with poor outcomes of high tibial osteotomy (HTO). However, there has been no report on the efficacy of HTO in the presence of kissing lesions. The purpose of this study was to compare clinical and radiographic outcomes of HTO between kissing lesion and non-kissing lesion groups. Materials and Methods Of th...

Data on meniscal repair after anterior cruciate ligament (ACL) reconstruction (ACLR) is scarce. This study aimed to report clinical outcomes and failure rate for isolated repairs in patients with a prior history of ACLR. was collected who underwent stable knee ACLR minimum follow-up 2 years. Preoperative evaluation stability performed instrumented differential laxity. Tegner activity scale, ACL...

Objectives: To identify synovial fluid biomarkers associated with midterm postoperative outcomes in patients undergoing arthroscopic partial meniscectomy (APM). Methods: Subjects were prospectively enrolled a cohort of who had aspirated from their knee on the day surgery prior to APM. Biomarker analysis was performed. Preoperative patient-reported outcome (PRO) scores including VAS pain, Lyshol...

Introduction: The potential of autologous matrix-induced chondrogenesis (AMIC) to restore unipolar focal chondral defects the knee is promising. However, outcome compared microfracturing (MFx) for certain defect sizes (2–3 cm2) still uncertain. Therefore, present study primary isolated AMIC versus MFx in a cohort patients with borderline sized at midterm follow-up. Methods: Patients who underwe...

BACKGROUND Many patient-based knee-rating scales are available for the evaluation of athletic patients. However, there is little information on the measurement properties of these instruments and therefore no evidence to support the use of one questionnaire rather than another. The goal of the present study was to determine the reliability, validity, and responsiveness of four knee-rating scale...

BACKGROUND Clinical and biomechanical studies have demonstrated the increase in contact pressure and progressive deterioration of the tibiofemoral compartments that occur after partial or complete meniscectomy. Meniscus transplantation has been indicated for the symptomatic postmeniscectomy patient to alleviate symptoms and potentially prevent the progression of articular degeneration. PURPOS...
