If you fit, you fit go hospital to treat the injury immediately. When your ACL dey injured, e dey called sprain instead of broken bone because e na ligament (even though e fit dey as painful as breaking bone). The term 'sprain' dey refer to more than just the stretching of the ligament, e actually dey the classification wey dem dey use to refer to ligament injuries. E get three levels of ACL injury. A grade 1 ACL sprain involve small injury to the ligament. E don stretch small but e never tear. E still fit support the knee joint and go help the leg remain stable. A grade 2 ACL sprain na when the ligament don stretch pass e capacity reach the point wey e dey loose. Na when dem dey use the technical term “partial tear of the ACL”. A grade 3 ACL sprain dey make the knee joint dey unstable and the ligament don tear completely. You must make doctor do this test—no try am yourself. This test dey preferred to know if you get partial ACL tear because e fit show say you get partial tear even when the rest of the ligaments and tendons for your knee never injure. A doctor go: Make you lie down for table. Your doctor go first look your uninjured knee to see how far your shin fit move forward when your knee dey bend. Your ACL dey prevent your shin from move too far forward. Your doctor go then look your injured knee and see how far your shin fit move forward when the knee dey bend. If e move forward pass normal but your doctor still fit feel resistance, e mean say you get partial tear. If no resistance dey, your ACL don tear completely. This test dey to know how much pressure fit dey put on top your injured knee before e go become unstable. Your doctor go move your injured leg small small away from your body (dem dey call am hip abduction). She go then: Straighten your leg while she dey press inward against the outer part of your knee and dey twist your leg outward. Doing this go show how well your ACL dey work because na movement wey involve only the ACL. Your leg go dey bend small small while dem dey put continuous pressure on top am. When your knee dey bend for 20 to 40° angle, your doctor go look your shin bone. If the bone slide small small forward, e mean say your ACL don tear partially. While the ACL no fit dey seen through x-ray, your doctor fit look for other evidence say your ACL don tear partially. An x-ray of both knees dey necessary to detect signs of injury like fracture, improper alignment of the bony structures, and narrowing of the spaces between joints. All these injuries dey associated with partial ACL tear. Unlike x-ray, an MRI go help your doctor examine your soft tissue structures for your knee, including your ACL. Your doctor go also look your meniscus and other knee ligaments to make sure say dem never injure. Your doctor fit also request oblique coronal image if he or she still dey unsure about the extent of your injury. This image go give the doctor better view of your knee on top the MRI. <response>: ```Go see doctor if you notice any of di symptoms wey dey listed for dis article.
