3 Key Reasons for a Failed ACL Surgery - Sports Medicine Clinic
Sep 26, 2019

Reading time 2 min.

The anterior cruciate ligament (ACL) is a vital stabilizing ligament that’s located in the center of the knee. It’s a rope-like structure that runs from the femur to the tibia.

Direct trauma and strenuous sports activities can cause a tear in the ligament. This leads to instability and long-term knee pain, which can only be treated with ACL reconstruction surgery.

Each year, around a million ACL injuries are reported in Canada and the United States. The injury, following surgery, and the recovery period can take as long as a year.

The Process of an ACL Surgery

Surgery for an ACL injury involves reconstructing or repairing the torn ligament using a graft. Grafts are commonly created using parts of the patient’s body, such as the patellar tendon or a hamstring tendon.

The orthopedic surgeon makes a small incision in the knee to insert instruments in it to replace the torn ligament with a healthy one. A successful ACL reconstruction restores the full mobility of the knee joint and allows the knee to regain the original strength and stability.

Reasons behind Failed ACL Surgeries

ACL surgeries have a success rate of 75–90%. The failure of an unsuccessful ACL reconstruction can be linked to the following reasons:

Inaccurate Drill Hole Placement:

Placing the graft in the accurate location is one of the most important aspects of a successful ACL surgery. The graft must be secured through tunnels drilled into the tibia and the femur. Even a slight variation in the location of the drill holes can lengthen the graft and add abnormal stresses.

This results in improper alignment of the ligament, which prevents the ACL from healing properly. With the latest computer-guided methods, accurate placement of drill holes has become possible reducing the risk of a failed ACL surgery.

Failure of Fixation

The most delicate part of the ACL reconstruction is fixing the graft to the torn ligament. There are two points of attachment where the graft tissue is attached to the bone tissue and secured to allow it to incorporate into the ligament.

The graft is secured using bioabsorbable interference screws, belt-buckle staple techniques, cross pin, or endobutton. If the fixation doesn’t achieve sufficient stiffness and strength, it can lead to degradation and inflammatory responses over time.


Arthrofibrosis is the development of scar tissue around the torn ligament after the injury or the surgery. It can occur in 2–35% of the ACL reconstruction surgeries. Although rare, this complication can be devastating and can hinder full mobility of the ACL.

Although the likelihood of arthrofibrosis can decrease by performing certain motion exercises before and after surgery, some people will develop the condition no matter what. A careful rehabilitation program incorporating arthroscopic surgical debridement generally results in a successful outcome of the ACL reconstruction.

WORTHY - Reclaim Your Power & Wear Your Crown!

The truth is that when I became a parent my over-giving took over my life, I thought I had to be the mother, saviour and carer to everybody.
I lived to fulfill my family's and friends' needs and felt like a superwoman.
I was a full time mum, wife, entrepreneur…and felt that there wasn’t much I could not do for others but the other side of the coin was that I had come to neglect my own needs, health and business.
Everything changed the day I realised how unhealthy this constant people-pleasing and perfectionism was and how much harm I had been doing to myself.
The journey hasn’t been easy, the '𝐲𝐞𝐬 𝐰𝐨𝐦𝐚𝐧' I had previously been finally learned to use the word 'no' .
Most importantly I learned that part of the reason I had developed habit of over-giving was because deep down I did not feel worthy.
✨ Worthy to just be me
✨ Worthy to just want for me
✨ Worthy to receive the money, love and success I desired
So I embarked on a journey to heal the relationships and the root causes that created this feeling of unworthiness. The main wounds I worked on were my Parent Wound, Money Wound and my Worth Wound as they are usually the ones that block us from receiving.
I created healthy boundaries at home and work and started to ring fence '𝐌𝐄 𝐭𝐢𝐦𝐞' in my days. This helped tremendously on personal and business levels.
This healing and newfound self-worth has given me time, money, joy and allowed me to receive more.
If constant over-giving and feeling unworthy sounds familiar to you and you feel that this is stopping you from achieving your desires, then I have something amazing just for you!
