Sports and exercise-related injuries represent an important challenge for public health because they may reduce physical activity participation, impair functional capacity, and increase healthcare utilization. This study analyzed the effectiveness of evidence-based sports injury-prevention programs and their potential integration into health-promotion policies for the general population. A structured literature review based on the Scientific Method was conducted using systematic reviews, meta-analyses, randomized controlled trials, consensus statements, and international guidelines. The analysis focused on strength training, neuromuscular exercises, balance and proprioception, structured warm-up programs, training-load management, adherence, implementation, and policy-level strategies. The reviewed evidence showed consistent reductions in injury occurrence with structured exercise-based interventions, with strength training, proprioceptive training, neuromuscular programs, and preventive warm-ups demonstrating particularly favorable outcomes. Higher adherence was associated with greater preventive effectiveness, emphasizing the importance of consistent implementation. Most of the available evidence was concentrated at the individual level, while community, organizational, and policy interventions were less frequently represented. The findings support a multicomponent and multilevel approach in which physical preparation is combined with education, progressive workload management, organizational support, safe environments, and public health strategies. Integrating these measures into schools, fitness centers, recreational sports programs, healthcare services, and community settings may contribute to reducing preventable injuries without limiting participation in physical activity. Sports injury prevention should therefore be incorporated into broader health-promotion policies aimed at creating safer, sustainable, and equitable opportunities for active living.

Occult osteochondral lesions represent an important challenge in sports medicine because they may remain undetected during initial assessment despite persistent pain, swelling, mechanical symptoms, and functional limitation. This study analyzed the role of diagnostic imaging, clinical and structural evolution, and return-to-sport criteria in athletes with osteochondral injuries, with particular emphasis on the knee and ankle. An integrative descriptive and analytical review was conducted using the Scientific Method, incorporating evidence related to magnetic resonance imaging, computed tomography, CT arthrography, conservative management, surgical treatment, rehabilitation, and athletic recovery. The findings demonstrated that conventional radiography has limited sensitivity for early osteochondral abnormalities, whereas magnetic resonance imaging provides superior visualization of cartilage integrity, bone marrow edema, subchondral changes, and lesion stability. Computed tomography and CT arthrography offer complementary value for defining osseous architecture and selected cartilage-surface abnormalities. Clinical improvement and radiological recovery were not consistently parallel, indicating that symptomatic improvement does not necessarily imply complete structural restoration. Surgical procedures such as bone marrow stimulation, fixation, osteochondral transplantation, and cartilage restoration showed favorable clinical and return-to-sport outcomes in appropriately selected patients, although return to the pre-injury level was consistently lower than return to sport at any level. The reviewed literature also revealed substantial heterogeneity in rehabilitation protocols and a predominant reliance on time-based criteria for sports clearance. Overall, the evidence supports an individualized and multidimensional return-to-sport approach integrating symptoms, range of motion, muscle strength, neuromuscular control, tolerance to loading, sport-specific performance, psychological readiness, and imaging follow-up when clinically indicated. Early diagnosis and criterion-based rehabilitation may contribute to safer athletic reintegration and improved long-term preservation of joint function.
