PCL Tear Symptoms And Diagnosis
Understanding Posterior Cruciate Ligament (PCL) Injuries: A Comprehensive Guide
The posterior cruciate ligament (PCL), located at the back of the knee, connects the femur (thigh bone) to the tibia (shin bone), playing a pivotal role in stabilising the knee and facilitating smooth movement. An injury to the PCL, through a sprain or tear, disrupts this function, leading to what is known as a PCL injury.

Who Is at Risk?
PCL injuries are not exclusive to athletes, though individuals participating in skiing, baseball, football, or soccer may find themselves more susceptible due to the nature of these sports.
Prevalence of PCL Injuries
Compared to anterior cruciate ligament (ACL) injuries, PCL injuries are relatively rare, constituting less than a fifth of all knee ligament injuries. They often occur alongside other ligament injuries, with isolated PCL injuries being even rarer.
Impact of a PCL Injury on the Body
PCL injuries are classified into four grades, reflecting the severity of the damage from a partial tear (Grade I) to a complete tear with instability (Grade III) and additional ligament damage (Grade IV). The severity of symptoms can range from mild to severe, potentially affecting the knee's stability and function over both short and long term.
Mobility with a PCL Injury
Walking capabilities post-injury can vary, with some individuals managing mild cases without significant difficulty, while others may struggle with severe damage.
Symptoms of a PCL Injury
Common indicators of a PCL injury include progressive pain, swelling, a sensation of instability, stiffness, and challenges with mobility such as difficulty descending stairs.
Diagnosing a PCL Injury
A healthcare professional will evaluate symptoms, perform a physical examination, and may request imaging tests like X-rays, MRIs, or CT scans to assess the extent of the injury.
Treatment Options
Treatment depends on the injury's severity and may range from the use of crutches and knee braces to support the joint, to physiotherapy for strengthening and stabilisation, and potentially surgery for severe cases. Post-surgical risks include infection, bleeding, blood clots, and knee stiffness, although these are rare.
Healing Timeframe
Recovery durations vary, with mild injuries potentially healing within 10 days and post-surgical recoveries extending to six to nine months.
Home Management
Home care includes rest, ice application, compression, elevation, and NSAIDs for pain and swelling reduction.
Preventing PCL Injuries
While it may be challenging to prevent PCL injuries entirely, maintaining knee health through stretching, employing proper technique during physical activities, and exercising caution can mitigate risk.
Prognosis and Recovery
The prognosis for PCL injuries ranges from complete recovery in minor cases to the potential for knee weakness and re-injury in severe cases. Post-surgery, most individuals see improved stability and mobility, though continued precautionary measures may be necessary during physical activities.
Returning to Daily Activities
The timeline for returning to work or school post-injury varies, with sedentary jobs allowing for a quicker return than more physically demanding roles.
When to Seek Medical Advice
Immediate medical consultation is advised for any signs of pain, swelling, instability, numbness, or discolouration in the knee post-injury. Prompt attention ensures an accurate diagnosis and tailored treatment plan.
Living with a PCL Injury
Living with a PCL injury requires adapting to the limitations it imposes and following through with prescribed treatments and rehabilitation. Monitoring symptoms and maintaining communication with healthcare providers are key to navigating the recovery process successfully.
