Posterior Cruciate Ligament Injury

The posterior cruciate ligament (PCL) is a strong fibrous tissue present inside the knee joint. The PCL along with the anterior cruciate ligament (ACL) plays an important role in the stabilization of the knee joint. The PCL may be injured while playing sports, accidental slipping, or a motor vehicle accident.

PCL injuries occur less often than the more common ACL injuries. While low-grade PCL injuries may be managed nonsurgically, high-grade injuries usually require surgical management.

Anatomy

The posterior cruciate ligament attaches the inner side of the lower thigh bone with the back of the upper shin bone. The cruciate ligaments are rope-like tough structures that stabilize the knee during day-to-day activities such as walking, turning, twisting, running, etc.

The PCL ligament consists of two bundles, the anterolateral bundle, and the posteromedial bundle. While the anterolateral bundle is taut in a bent knee, the posteromedial bundle is taut in a straight knee.

The PCL primarily functions to prevent excessive movement of the shin bone against the thigh bone. The PCL also prevents excessive inner rotation of the leg in both flexion and extension. In a straight knee, PCL also functions to prevent excessive side-to-side movement of the knee.

The PCL is also responsible to prevent overshooting of the leg on straightening. As the PCL functions in conjunction with the ACL and the collateral ligaments, injury to the PCL often occurs in association with other knee ligament/meniscus injuries.

Injury

The PCL injury may occur in conjunction with other knee ligament injuries or may occur as an isolated injury. The injury mostly occurs as an acute injury following trauma but may also occur as a chronic injury secondary to repeated trauma.

The most common mechanism of PCL injury is falling with bent knees. As the shin bone is pushed against the thigh bone, the PCL ruptures/tears. The injury may also occur as a result of dashboard injury during a motor vehicle accident when the bent knee hits the dashboard which pushes the shin bone back against the thigh bone.

Other mechanisms of injury include traumatic knee dislocation, knee rotational injuries, etc. Athletes playing sports such as football, rugby, soccer, basketball, etc are especially vulnerable to PCL injuries.

Symptoms

The symptoms of PCL injuries as a result of acute injury present as acute pain, swelling, and difficulty walking. Patients may complain of laxity of the knee joint with a sensation of the knee giving away. Patients with isolated PCL injury may at times present with minimal symptoms. Similarly, patients with chronic PCL tears may present with only mild knee pain and instability.

Diagnosis

The physician elicits a detailed history surrounding the injury. The mechanism of injury may point towards the probable structure damaged in the knee. The physical examination involves special tests and maneuvers to test the integrity of various ligaments in the knee.

Commonly, the physician performs a posterior drawer test. The posterior drawer test involves the patient lying on the bed with their back towards the bed. The patient’s knee is bent at 90 degrees and the physician tests by trying to push the leg back against the thigh after first trying to pull the knee forward. The test is positive if there is excessive laxity on pushing the leg back.

The physician grades the PCL injury by the degree of laxity of the knee on performing the posterior drawer test. Similarly, the physician tests for the integrity of the other ligaments and meniscus in the knee.

An X-ray is usually requested to look for any bony injuries. Severe PCL injuries may result in an avulsion of a bony fragment along with the ligament which may be visible on an X-ray. The ligaments and other soft tissues are most clearly recognized on an MRI.

Management

Acute injuries with a bony avulsion may necessitate immediate surgery to fix and reconstruct the PCL ligament. Such injuries are usually associated with injuries to other structures of the knee. Grade 1 and 2 injuries are generally managed with nonsurgical techniques.

The physician may prescribe pain medication to help control pain. Icing is advised to help control the swelling. Icing and compression bandage helps to reduce swelling after acute injury. A knee brace is usually advised to help provide stability to the knee and help in healing.

Surgical reconstruction is done in case the conservative management fails to provide relief and in grade 3 and 4 injuries. The surgical reconstruction involves either the use of allograft or autograft. The allograft is harvested from a cadaver while an autograft is harvested from the patient’s own body.

The Achilles tendon, hamstrings tendon, or quadriceps tendon may be used as an autograft for PCL reconstruction. The reconstruction is usually done with the use of an arthroscope. In arthroscopic surgery, the surgeon uses keyhole incisions to insert miniature instruments along with a camera that projects the view on an outside display.

A rehabilitation program is started after the surgery to help the patient regain the strength and flexibility of the muscles surrounding the knee joint. The patients are able to get back to their day-to-day activities and sports after the rehabilitation period.

I had such a wonderful experience with Complete Orthopedics in Stony Brook. Not only did Dr. Kuo fix my broken wrist with such kindness and care, but the office staff, including Billing, Reception and the X-Ray Technician, was always so helpful, going out of their way to ensure that each patient felt welcome, answering any questions with a smile, and ensuring any issues with insurance/billing were handled with the utmost professionalism. I highly recommend their practice!

I'm very happy St. Catherine's sent me to this office for treatment after I broke my collar bone! Unfortunately the break was too severe to repair on its own and I had to have it rebuilt a week after the injury. Dr. Vaksha did a great job fixing it. I'm three months out, and I have full use of the arm and shoulder. The whole office staff is very professional, accommodating, and welcoming. I hope to not need orthopedic services again, but Dr. Vaksha will be my number one choice if I or anyone in family suffers such am injury.

Scheduling my appointment was quick and easy. The staff was super friendly and down to earth. I was seen on time. The appropriate test, “x-rays” were taken before the conversation with doctor, something I really liked, test for analysis and conversation was done upfront. Dr. V had a great personality and was no BS, straight forward diagnosis and a play on next steps. I am happy I found them and would refer them to friends and family.

After suffering from a severe ankle injury Dr. V was able to help me heal and return back to work completely to a job where I stand for 12 hours a day. The office is very clean and I appreciated the reminders of my appointments via phone call and through text. The patient portal made it easy for me to access all my documents including work notes. The office staff is wonderful and Rebecca was able to schedule me with a busy schedule and awesome at answering all of my questions including referring me to a great physical therapy office. I highly recommend this office to anyone who’s looking for knowledgeable and kind orthopedic office.

I was rear ended in an auto accident , Dr Vashka was recommended by a friend of mine .I was experiencing Back , neck , and shoulder pain . After a thorough examination and given exercises to do at home , I am feeling much better , and I ended up avoiding surgery . The staff at Complete Ortho is extremely attentive and show great care when making an appointment and are very friendly and i never waited more than 5 minutes for my appointment . So I would strongly recommend Complete Orthopedics for any aches and pains that one might be experiencing.....

It was the afternoon of Friday Sept. 24. We were in Pt. Jefferson and my wife, Mary Ann, broke her hip. We went to Mather Hospital and it was determined that she would have to have an operation to have it repaired. This would be her third time under the knife in the past year. It just so happened that we were very fortunate enough to have Dr. Karkare, who was on standby, perform the surgery. He put in a rod and two screws in her hip. She spent a few days in the hospital and then went to Gurwin rehabilitee for another few weeks.It has now been almost six weeks and we both worked the election the other day. If it wasn’t for Dr. Karkare’s expertise she never would have been able to work. She is able to walk with a walker and is doing physical therapy three times a week.We can not thank the doctor enough for the compassion and dedication that he puts into his work. It allows Mary Ann do the things that she likes to do, even on a limited basis for a while. I know that with her will, perseverance and the great work that the surgeon performed she will be back on her feet in no time.Sincerely:John V. PlumpEast Northport, NY 11731

In the year of 2018 I was referred to Dr. Karkare because I was experiencing severe knee joint pain. After exhausting physical therapy and trying to labor through the pain, I had to make a quality of life decision. Total knee replacement was the only viable option. Dr. Karkare made my decision easy as he walked me through the whole process from surgery to recovery.On 12/13/19 ( Friday the 13th) I enter Lenox Hill Hospital in great hands. From the time I entered Dr. Karkare’s office for the first time until now, his staff has been amazing. Andrea the medical coordinator walked me through all the paper work and necessary preparations for the surgery. Courtesy and kind would be an understatement. Dr. Karkare went over and beyond from the wellness checks and phone calls all to assure me that I was important to him. This was the right decision no pain and no limp. Complete Orthopedics should be your choice!

I suffered with pain in both knees for years. My orthopedic doctor kept recommending knee replacement . I fought it for years, as I was just afraid. When I had no choice and could barely walk , it was recommended I see Dr. Karkare. We set up a consultation and my wife and I left his office feeling totally confident and comfortable with moving ahead with the surgery. He explained everything to us, and the office staff set everything up for us and made the process easy. So about one month after our initial meeting I had the first knee done. I was up walking mere hours after the surgery, and on the workout machines the next morning. I went home two days after the surgery, and yes walked my daughter down the aisle at her wedding only one week after the surgery without even a cane! Three months later I had the other knee done and went home the very next day. Dr. Karkare put my fears to rest . I would highly recommend him. His expertise gave me my life back. Thank you Dr. Karkare.SincerelyVito Congro
