Treatment of Knee Chondral Defects in Athletes

Background: Knee cartilage defects are a common injury among athletes, often resulting from acute trauma or repetitive stress. These defects can lead to significant pain and functional limitations, hindering an athlete's ability to perform at their best. Due to its avascular nature, articular cartilage has limited healing capacity, making effective treatment essential for recovery and return to sport. There are various surgical and nonsurgical interventions, each tailored to the specific characteristics of the defect and the athlete's needs. Understanding these treatment options is crucial for optimizing outcomes and facilitating a safe return to sports activities. Methods: This study reviews current treatment methods for knee cartilage defects in athletes, focusing on both surgical and nonsurgical approaches. The authors conducted a comprehensive literature review from ۲۰۱۰-۲۰۲۴, analyzing studies detailing the prevalence of cartilage defects, treatment outcomes, and factors affecting recovery in athlete populations. Key considerations included defect size, location, age of the athlete, previous injuries, and level of sports participation. The review also examined rehabilitation protocols related to various surgical techniques to assess their impact on recovery timelines and return-to-play rates. Results: The review identified several treatment options for knee cartilage defects that significantly vary based on defect characteristics and athlete-specific factors. For small defects (less than ۲ square centimeters), nonsurgical treatments such as physical therapy and intra-articular injections (like corticosteroids or hyaluronic acid) are often effective. For larger defects, surgical interventions such as microfracture, osteochondral autograft transfer (OATS), and autologous chondrocyte implantation (ACI) are commonly used. Microfracture remains one of the most employed techniques due to its relative simplicity; however, it typically results in fibrocartilage rather than true hyaline cartilage, which may not withstand the high mechanical demands of sports activities. Additionally, ACI and OATS have shown better long-term outcomes for larger defects but require more extensive rehabilitation. The study also highlighted that adherence to rehabilitation protocols is vital for successful outcomes, with return-to-play rates ranging from ۴۴% to ۹۵% depending on the technique used and the athlete's compliance with postoperative care. Conclusion: Effective management of knee cartilage defects in athletes requires an appropriate approach that considers individual characteristics and specific sports demands. While various treatment options are available, their efficacy is influenced by factors such as defect size, location, and previous injuries. Early intervention is also crucial to prevent further cartilage deterioration and facilitate optimal recovery. Future research should focus on refining existing techniques and exploring
