Purpose/reason of the research: The anterior cruciate ligament (ACL) is an important ligament in maintaining knee function. In patients with anterior cruciate ligament (ACL) injury, concomitant intra-articular lesions are usually seen. It has been reported that approximately 43% of all patients with ACL tears have associated lateral or medial meniscal injuries.

Injury associated with a tear of the meniscotibial ligament in the posterior horn of the medial meniscus is defined as a RAMP lesion. Because the RAMP lesion is located within the posteromedial "blind spot", it has historically been underdiagnosed.

It has been reported that 9-17% of all ACL tears have RAMP lesions. RAMP lesions have been found to increase the force on the ACL. Injury to the meniscotibial ligaments has been shown to increase rotational instability of the knee.

Based on the available literature, there is a discrepancy between authors regarding the repair of a RAMP lesion during an acute ACL surgery. In chronic ACL rupture, some authors have suggested that the RAMP lesion has a suitable biological environment for healing.

thinks. However, excessive mobility of the meniscocapsular junction has been reported in RAMP lesions during knee flexion and extension. It has been suggested that these lesions are different from other peripheral tears and are not suitable for spontaneous healing. It is suggested that meniscal RAMP lesion repair will be the most effective approach. Rehabilitation after repair of a RAMP lesion depends on whether the repair is performed concurrently with ACL surgery. When performed with an ACL surgery, the process is followed according to the ACL rehabilitation protocol.

Even if the functionality of the knee is fully restored in the post-ACL surgery period, not all patients can return to their previous level of sportive performance due to various psychological, social and physiological factors. In the literature, different information can be found as criteria for returning to sports after ACL surgery. The rate of returning to sports was reported as 65-88% in patients with ACL reconstruction, and 19-82% in patients who were followed conservatively. However, there are few studies with short- or long-term follow-up after the identification and treatment of RAMP lesions. Accordingly, our aim in this study is to comprehensively evaluate the return to sports of participants who have undergone isolated anterior cruciate ligament surgery and who have had simultaneous RAMP lesion repair with anterior cruciate ligament surgery.

This assessment will provide the opportunity to examine functional capacity, balance, psychological state, activity level and pain with different measurement methods.

Material and method of the research: The study will consist of 2 groups, including 12 participants who have undergone isolated ACL surgery and 12 participants who have had simultaneous RAMP lesion repair in Istanbul Medipol Mega Hospitals Complex Orthopedics and Traumatology Unit, with a total of 24 participants.
