1. The ACL (anterior cruciate ligament) is an important stabilizer of the knee joint that prevents forward displacement of the tibia bone. 2. ACL injuries are most often caused by non-contact injuries involving sudden stops or changes in direction and can range from a minor stretch (Grade I) to a complete tear (Grade III). 3. ACL injuries are classified into three grades based on the severity of the tear, with Grade I being a minor stretch and Grade III being a complete tear where the ligament is torn into two parts resulting in knee instability.

3. Definisi Cedera LCA
• Anterior cruciate ligament (ACL) injuries are most often a result of
low-velocity, noncontact, deceleration injuries and contact injuries
with a rotational component. (Medscape, 2014)

4. Menurut Academia.Edu
• Robekan di salah satu ligament lutut yang menghubungkan tungkai
atas dan tu ngkai bawah.

5. Menurut Mayoclinic
• An ACL injury is the tearing of the anterior cruciate (KROO-she-ate)
ligament, or ACL, inside your knee joint. An ACL injury most
commonly occurs during sports that involve sudden stops and
changes in direction — such as basketball, soccer, tennis and
volleyball. (Mayoclinic, 2013)

6. Klasifikasi Cedera LAC
• Berdasarkan tingkat keparah cedera, sbb :
1. GRADE I : Sebuah hamparan ringan, dengan nyeri ringan dan bengkak
tetapi tidak ada perpanjangan permanen atau kerusakan pada
ligamentum.
2. GRADE II : Ligamentum tertarik keluar dan di perpanjang. Ada rasa sakit
umumnya dan bengkak yang disertai memar. Ligamentum akan sembuh
tanpa operasi. Namun memiliki beberapa kelemahan, namun sendi dapat
berfungsi normal dengan sedikit ketidakstabilan.
3. GRADE III : Ligamentum tertarik jauh sehingga robek. Relative sedikit
sakit. Sendi sangat tidak stabil bahkan sulit menahan tongkat.Lutut
terlepas atau buckle. Memar disekitar lutut dan diperlukan operasi
perbaikan.

7. Classification ACL Injuries (BrooklynSoccer)
• An ACL injury is classified as a grade I, II, or III sprain.
Grade I sprain
• The fibres of the ligament are stretched, but there is no tear.
• There is a little tenderness and swelling.
• The knee does not feel unstable or give out during activity.
• Grade II sprain
• The fibres of the ligament are partially torn.
• There is a little tenderness and moderate swelling.
• The joint may feel unstable or give out during activity.
• Grade III sprain
• The fibres of the ligament are completely torn (ruptured); the ligament itself has torn completely
into two parts.
• There is tenderness (but not a lot of pain, especially when compared to the seriousness of the
injury). There may be a little swelling or a lot of swelling.
• The ligament cannot control knee movements. The knee feels unstable or gives out at certain
times.
