Determination of Factors Influencing Tissue Effect of Thermal Chondroplasty: An Ex Vivo Investigation

“…Mitchell et al proposed that in addition to power setting, the selection of probe was also an important factor. Compared with the 110W power and 125 μm probe, the 50W power setting and 25 μm probe had the least influence on the tissue ( Mitchell et al, 2006 ).…”

“…Voss et al also confirmed that there was a strong relationship between temperature increase and chondrocyte death ( Voss et al, 2006 ). The chondrocytes were more likely to restore their vitality after thermal injury when the temperature was less than 50°C ( Mitchell et al, 2006 ). Therefore, the local temperature should also be properly controlled to ensure the safety of AC while achieving the desired clinical results.…”

Articular cartilage lesion is a common disease to be treated by arthroscopic surgery. It will eventually progress to osteoarthritis without proper management, which can affect patients’ work and daily life seriously. Although mechanical debridement and laser have been used clinically for its treatment, due to their respective drawbacks, radiofrequency has drawn increasing attention from clinicians as a new technique with more advantages. However, the safety and efficacy of radiofrequency have also been questioned. In this article, the scope of application of radiofrequency was reviewed following an introduction of its development history and mechanism, and the methods to ensure the safety and effectiveness of radiofrequency through power and temperature control were summarized.

“…However, the high intra-articular temperature associated with this method may have the potential to partially or completely destroy the joint cartilage (25) . Temperatures higher than 50°C have been defined as a critical threshold for chondrocyte death (26) . Occurences of necrosis associated with radiofrequency use depend on the quantity and duration of application of the energy (27) .…”

SThe treatment of chondral knee injuries remains a challenge for the orthopedic surgeon, mainly owing to the characteristics of the cartilage tissue, which promote low potential for regeneration. Chondral lesions can be caused by metabolic stimulation, or by genetic, vascular and traumatic events, and are classified according to the size and thickness of the affected cartilage. Clinical diagnosis can be difficult, especially due to insidious symptoms. Additional tests, as Magnetic Resonance Imaging (MRI), may be needed. The treatment of these lesions usually starts with non-operative management. Surgery should be reserved for patients with detached chondral fragments, blocked range of motion, or the failure of non-operative treatment. The surgical techniques used for the treatment of partial thickness defects are Debridement and Ablation. These techniques aim to improve symptoms, since they do not restore normal structure and function of the cartilage. For full-thickness defects (osteochondral lesion), available treatments are Abrasion, Drilling, Microfracture, Osteochondral Autologous and Allogeneic Transplantation, and biological techniques such as the use of Autologous Chondrocyte Transplantation, Minced Cartilage and stem cells.
