Outcomes of Particulated Juvenile Articular Cartilage and Association With Defect Fill in Patients With Full-Thickness Patellar Chondral Lesions.
Orthop J Sports Med
June 2024
The Patellofemoral Center, Department of Orthopedic Surgery, Hospital for Special Surgery, New York, New York, USA.
Background: Cartilage restoration procedures for patellar cartilage defects have produced inconsistent results, and optimal management remains controversial. Particulated juvenile articular cartilage (PJAC) allograft tissue is an increasingly utilized treatment option for chondral defects, with previous studies demonstrating favorable short-term outcomes for patellar chondral defects.
Purpose: To identify whether there is an association between defect fill on magnetic resonance imaging (MRI) with functional outcomes in patients with full-thickness patellar cartilage lesions treated with PJAC.

Objective: To summarize the classic and latest treatment techniques for localized knee cartilage lesions in clinical practice and create a new comprehensive clinical decision-making process.
Methods: The advantages and limitations of various treatment methods for localized knee cartilage lesions were summarized by extensive review of relevant literature at home and abroad in recent years.
Results: Currently, there are various surgical methods for treating localized knee cartilage injuries in clinical practice, each with its own pros and cons.
Cartilage restoration procedures have gained increased traction over the years as a treatment for chondral defects in relatively younger patients. A critical assessment of study populations for confounders is vital to interpret results in a valid manner. This is particularly true when assessing outcomes of cartilage restoration procedures in the patellofemoral compartment because there is often great heterogeneity associated with this population.

Article Synopsis
- The objective of the text is to give a detailed overview of different surgical options for treating osteochondral lesions of the talus (OLT) and their implications for clinical practice.
- Various surgical treatments have been identified, each showing promise with distinct advantages and disadvantages, particularly in terms of short-term and long-term effectiveness.
- A range of techniques such as autologous therapies, juvenile cartilage allografts, and new approaches like cell transplantation and autologous matrix-induced chondrogenesis are discussed, but some methods face challenges like high costs or inadequate supporting research.
Particulated Juvenile Articular Cartilage Allograft Transplantation for Patellofemoral Defects Shows Favorable Return-to-Sport Rates and Patient-Reported Outcomes.

December 2024
Department of Orthopedic Surgery, Columbia University Irving Medical Center, New York, New York, U.S.A.. Electronic address:
Purpose: To report return-to-sport rates, postoperative patient-reported outcomes (PROs), complication rates, and reoperation rates of a cohort of patients undergoing particulated juvenile articular cartilage (PJAC) allograft transplantation for patellofemoral articular cartilage defects.
Methods: We performed a single-institution retrospective review of all patients with patellofemoral articular cartilage defects who received PJAC allograft transplantation from 2014 to 2022. Baseline demographic characteristics and surgical data, including concomitant surgical procedures, were collected.
