ClinicalTrials.gov Identifier:	NCT00613535

Purpose

The purpose of this post-marketing surveillance study is to determine the proportion of study participants who demonstrate tissue stability, as seen using magnetic resonance imaging (MR), at the site of an ICRS Grade II or III (partial thickness) chondral tissue on the medial femoral condyle observed during arthroscopy 6 months earlier and treated using one of three standard clinical methods.

Primary Outcome Measures:

In vivo magnetic resonance imaging (MRI) features of the medial femoral condyle chondral lesion [ Time Frame: 6 months after arthroscopy ] [ Designated as safety issue: No ]

Arms	Assigned Interventions
No chondral treatment: No Intervention Chondral lesions left untreated during partial meniscectomy
Mechanical Shaver: Active Comparator	Device: Mechanical Shaver Mechanical shaver will be used to remove large chondral flaps and loose fragments
RF based chondroplasty: Active Comparator	Device: Paragon T2 Use Paragon device to debride after removal of larger chondral lesion flaps with mechanical shaver.

Detailed Description:

Fibrillated articular cartilage are commonly detected during arthroscopy when treating knee pathologies such as a torn meniscus or a damaged anterior cruciate ligament (ACL). The severity of these lesions is graded using a scheme such as the International Cartilage Research Society (ICRS) classification system. Grade I lesions are often left untreated, while Grade IV lesions require dedicated surgical intervention. Grade II and III lesions are frequently treated when they are encountered arthroscopically.

Currently, it is not known whether treatment of fibrillated articular cartilage is beneficial or whether one procedure is superior to another. Magnetic resonance imaging is the best technique currently available for non-invasive assessment of chondral lesions. The primary aim of the proposed study is to compare post-procedure MR imaging characteristics of fibrillated articular cartilage treated using one of the three standard of care measures: 1) no chondral debridement; 2) chondral debridement using the mechanical shaver; and 3) mechanical shaver debridement along with RF-based chondroplasty. The secondary aim is to determine the association between imaging features and clinical outcomes.
