Soft tissue injuries around the knee that occur during sports activities can reduce athletes' performance and negatively impact their quality of life by affecting their sports careers due to long-term effects. The most common periarticular soft tissue injuries among athletes are medial patellofemoral ligament injuries, quadriceps and patellar tendon injuries, knee joint bursitis, anterior impingement syndrome, Hoffa`s fat pad, popliteal swelling, periarticular tendinitis and iliotibial band syndrome. Recognition of these injuries is essential for an effective treatment plan. Clinical examination, imaging techniques and sometimes invasive methods such as arthroscopy are used in the diagnosis of soft tissue injuries around the knee. Imaging modalities such as magnetic resonance imaging, ultrasound and radiography are important in determining the location, severity and differential diagnosis of the injury. The treatment plan is determined according to the location and severity of the injury and the needs of the athlete. Treatment options include conservative methods (such as rest, cold application, physiotherapy), surgical interventions (such as arthroscopy, open reconstructive surgery) and rehabilitation programs. In order to return to sport following these injuries, early diagnosis, appropriate treatment and effective management of comprehensive rehabilitation are essential to prevent recurrence of the injury.
