Lateral collateral ligament injuries introduction The lateral collateral ligament (LCL), also known as the fibular collateral ligament, is the primary varus stabilizer of the knee and isolated injuries are somewhat uncommon. In addition to the popliteus and the popliteofibular ligament, it provides stability to the posterolateral corner (PLC) of the knee. Case Vignette A 16 year old female soccer player presents to your clinic with left knee pain.
The goalie dove into her knees to try to get the ball and she sustained a blow to her anteromedial knee by the goalie’s shoulder. She did have immediate pain and trouble walking. On examination, she does not have laxity on her Lachman test and does not have increased rotation with the dial test.
There is no joint effusion. She does have 4 mm of laxity with varus stress and no laxity with valgus stress. Of the following options, what is the most likely treatment plan?
A) Orthopedic surgery referral B) Place in knee immobilizer for 2 weeks and reassess C) Early mobilization and physical therapy prescription D) Order MRI of her knee With the knee in extension, the LCL is approximately 6 cm ong and 3-5 mm thick. It extends from the lateral femoral epicondyle about 2 cm above the joint line to the fibular head. The LCL and biceps femoris tendon form a conjoined tendon.
There is an anterior oblique band (AOB), a band of fibrous tissue, that extends from the LCL to the lateral portion of the tibia. Some fibers of the AOB blend with the iliotibial band (ITB). It does not attach to the lateral meniscus and is described as cord-like as opposed to fan-like.
If you are experiencing symptoms that may be related to lateral collateral ligament injuries, it is important to see a sports medicine physician. Early evaluation and treatment typically lead to better outcomes. Do not ignore pain or symptoms that are limiting your activity.
