Understanding PCL Injury and Knee Stability
A PCL injury affects the ligament that stabilises the back of the knee joint. The posterior cruciate ligament connects the thigh bone to the shin bone and prevents the shin from moving too far backward during movement.
The knee contains several major ligaments that guide joint stability. The posterior cruciate ligament plays a critical role during walking, running, and changes in direction. When a PCL tear occurs, the knee may feel unstable or weak, especially during weight-bearing activities.
Many injuries occur during sports, motor vehicle accidents, or falls that drive the shin backward while the knee remains bent. Damage to the posterior cruciate ligament may range from mild stretching to a complete PCL tear.
Orthotics Plus clinicians assess knee stability and recommend appropriate orthotic support to assist recovery.
PCL Treatment at Orthotics Plus
Orthotics Plus has extensive experience in treating people with PCL injuries- ranging from elite athletes to everyday people.
We provide bracing and rehabilitation support. Our services are delivered at our Melbourne clinic locations.
Anatomy of the Posterior Cruciate Ligament
The posterior cruciate ligament sits deep within the knee joint. It connects the femur to the tibia and works with other ligaments to control knee motion.
The ligament guides backward movement of the tibia and supports joint alignment during walking and load-bearing activities. Damage to this ligament can alter knee mechanics and create long-term joint strain if left untreated.
A PCL injury may occur in isolation or alongside other knee ligament injuries. Accurate diagnosis helps determine the most appropriate treatment plan.
How PCL Injuries Occur
The PCL is most commonly injured via a blow to the anterior section of the tibia. Such a high-impact force displaces the tibia backwards to a degree beyond what the PCL can stretch to, resulting in a partial or complete tear.
Most patients injure their PCL while playing sports, from a fall or during a car accident.
The injury usually occurs when the knee is positioned at 90 degrees (such as sitting in a car), sustaining a physical impact that shifts the tibia backwards and tears the PCL.
Benefits of Early Diagnosis and Treatment
Early evaluation of a PCL injury improves the chances of successful recovery and reduces the risk of ongoing knee instability.
Improved Knee Stability
Proper management helps restore alignment between the thigh bone and shin bone. This stability supports safe movement during daily activities.
Protection of Joint Structures
When a PCL tear remains untreated, abnormal joint motion can place stress on cartilage and surrounding ligaments. Early intervention protects the joint.
Support During Rehabilitation
Specialised braces such as the Ossur Rebound PCL brace guide the position of the tibia during movement. This support helps protect the healing ligament.
Reduced Recovery Complications
Early clinical assessment and appropriate bracing may shorten pcl tear recovery time without surgery for many patients.
Choosing the Correct Brace for PCL Recovery
Historically, there have been general braces that were used to aid PCL recovery. Fortunately, there has been development in this area, and there are now specialised braces available.
At Orthotics Plus, we believe the most appropriate product is the Ossur Rebound PCL Brace for people who have sustained an isolated PCL injury.
In our experience, this device generally yields better outcomes as it provides the correct force at the correct time during normal activity rather than providing a static force. It is the brace that most sports medicine doctors and orthopedic surgeons recommend.
Assessment and Diagnosis of PCL Injury
Clinical Evaluation
A clinician evaluates knee movement, stability, swelling, and pain. The clinician observes walking patterns and assesses ligament stability through specific clinical tests.
Imaging and Medical Diagnosis
Medical professionals may recommend imaging, such as an MRI or an ultrasound, to confirm the severity of a PCL injury.
Orthotic Assessment
After diagnosis and referral, Orthotics Plus clinicians assess the need for specialised knee bracing that supports recovery and protects the ligament during rehabilitation.
Treatment Options for PCL Injury
Treatment varies depending on the severity of the injury and the activity level of the patient.
Non Surgical Management
Many patients recover from a PCL tear through structured rehabilitation and orthotic support. Knee braces that guide tibial alignment may help protect the ligament during healing.
Rehabilitation programs focus on strengthening surrounding muscles and improving knee stability.
Surgical Management
Severe injuries or combined ligament damage may require surgical reconstruction. Orthotic support may still play a role during postoperative rehabilitation.
Rehabilitation and Recovery
Recovery after a PCL injury often includes guided strengthening and controlled return to activity.
Clinicians work with rehabilitation teams to monitor knee stability during recovery. Structured exercise programs help restore strength and coordination around the joint.
Many patients ask about PCL tear recovery time without surgery. Recovery timelines vary depending on injury severity and rehabilitation progress. Some individuals return to normal activities within several months with appropriate treatment.

How the Rebound PCL Aids in PCL Recovery
The PCL in a healthy knee undergoes a normal stretch as the knee bends. Your PCL is under the maximum tension at about 90-110 degrees of knee flexion, or while the hamstrings are engaged and pulling the tibia backwards.
When the Ossur Rebound PCL is worn, a dial is used to shift the tibia forward via a force system. That force system is on a cam, which increases the force proportionally as the knee bends, thereby minimizing the stretch on the PCL when it is most needed.
The Rebound PCL aids the PCL in recovering “tighter”, meaning the ligament will be less attenuated. The knee should be more stable than if the person didn’t wear a brace at all.
The PCL brace helps to push the tibia back to where it should be and hold it in the correct position while it heals. Otherwise, the tibia will sag without this support.
We Support Both Surgical and Non-Surgical PCL Patients
If the physiotherapist or surgeon decides that conservative treatment is the best approach, our team at Orthotics Plus can help manage your treatment with a PCL brace.
Braces generally provide good outcomes for our patients. In some cases, we can fully prevent or postpone surgery.
Even if a surgeon repairs a PCL, a brace may still be needed. For example, if you have a multi-ligament injury or are very unstable, the surgeon may choose to operate and repair the PCL but also prescribe a PCL brace afterwards to protect the repair.
Some surgeons may also choose to lock your knee straight with a brace for a time following surgery to stop you from bending the knee too much while the graft heals.
Patient Experience of PCL Supports
Most often, Orthotics Plus will become involved in your treatment following a referral. It’s rare that we would diagnose a patient with a PCL injury before they are seen by a Physio/GP.
Once we fit a patient for a brace, we recommend appointments every two weeks at a minimum until they’re out of the brace to tighten up the posterior dial. If a patient is located a far distance from our office, we can liaise with other Allied Health professionals to assist with follow ups.
During the initial assessment with our team, we’ll always discuss with patients the expected timeline as well as treatment costs and the variable pathways that may occur.

Frequently Asked Questions
Symptoms may include knee pain, swelling, instability, and difficulty with weight bearing activities. Some individuals notice a feeling of the knee shifting backward.
Medical professionals perform clinical tests and may request imaging such as MRI to confirm damage to the posterior cruciate ligament.
Rehabilitation focuses on strengthening muscles around the knee and improving joint stability. Knee bracing may support the joint during recovery.
Many patients return to sporting activity once strength and knee stability improve. Recovery timelines depend on injury severity and rehabilitation progress.
Surgical reconstruction may involve risks such as infection, stiffness, or prolonged rehabilitation. Orthopaedic specialists discuss these risks during surgical consultations.
