Current Concepts in Anterior Cruciate Ligament Repair

Anterior cruciate ligament (ACL) repair is a procedure used to rebuild the ligament in the center portion of the knee. The ACL keeps the tibia (shinbone) in place. When this ligament is torn or damaged, it can cause the knee to buckle during physical activity.

How common is ACL ligament repair?

The ACL is one of the most commonly injured ligaments in the knee. Around 200,000 people ACL Tear2suffer some sort of injury to the ACL, and 100,000 ACL repair surgeries are performed annually. ACL injury incidence is higher in people who participate in high-risk activities, such as skiing, football, basketball, and soccer. It is common to see an injured ACL in combination with injury to the meniscus, collateral ligament, articular cartilage, and/or joint capsule.

What tissue is used to make the repair?

The ACL is often repaired using tissue grafting. The graft taken from the patient’s own body is called an autograft. The most common area for taking tissue is the hamstring tendon (kneecap tendon). When not possible to use the patient’s own tissue, an allograft (cadaver tissue) is used.

Why is ACL repair necessary?

ACL repair is done because the knee becomes unstable after a tear in this ligament. This will increase the chance of a meniscus tear. ACL repair is also used for treating knee problems, such as:

  • Knee pain
  • Knee instability
  • Inability to participate in usual activities

How do I prepare for ACL surgery?

After surgery, you will not be able to bear weight on the knee, so you should prepare your home. Have items you need within reach, and stock up on supplies. You need to arrange to have ACL Graftsomeone drive you home, and should notify the doctor of all blood thinners you are taking, as some of these must be held for several days before the procedure.

What happens when I arrive at the surgery center?

Be sure to arrive at the surgery center 60 minutes before your scheduled procedure. A nurse will go over the risks and benefits of the procedure, and ask you to sign a form of consent. After you change into a gown, the nurse will place an IV catheter in your arm.

How is the ACL repair performed?

After receiving anesthesia, the Gilbert sports medicine surgeon makes small incisions over the knee. The tiny, lighted camera is inserted into the knee so the doctor can visualize the structures (arthroscopic). The surgeon uses the camera and monitor to check the ligaments and repair the

What happens after surgery?

You will need time and effort if you wish to fully recover. You must follow a rehabilitation program for 4-6 months, and your ability to return to full activity depends on how well you follow this program.

What is the success rate of surgical ACL reconstruction?

Patients who have surgical reconstruction of the ACL have a success rate of 82-95%, according to clinical studies. Only 8% of patients experience graft failure or recurrent instability.

The Latest Advancements in Knee Replacement for Active Boomers

The majority of patients coming in for knee replacement surgery are in their 50s, according to Steven Haas who is heading the Knee Surgery and Attending Orthopedic Surgeon Department at the Hospital for Special Surgery based in New York City. If these statistics are compared with those of 20 years ago, there has been a rapid shift in demand for knee replacement surgery, especially for people in their 50s.

Why the sudden interest and growth of demand for the surgical procedure? The points responsible for this are new and innovative technologies that are being used now, especially in implant design and far more improved surgical techniques that are being used by orthopedic surgeons to meet with the growing demand for knee replacements. In addition, the growing number of baby boomers reaching older age has increased the numbers in need of the procedure.

The Latest in Knee Replacement Surgery

Only recently, the orthopedic community announced the arrival of the newest advancement for the surgery, i.e. a knee replacement implant that can last the patient as much as 30 years instead of the standard 10-15. Moreover, the implant has also been cleared by the FDA which means that those looking for ways to make their implants last longer, can opt for this.

VERILAST technology is used for making the implant that will make it possible for patients to possibly outgrow the implant, rather than the other way round. In addition to this, the implants are thought to be much more functional than the earlier versions, as is proved by a series of tests that researchers underwent before giving that verdict.

Adoption of Better Surgical Procedures and Techniques

Orthopedic surgeons have also changed their way of performing surgical procedures, by introducing techniques such as minimally invasive surgery, which helps in decreasing trauma to the patient, as much as possible, which in turn leads to a faster recovery.

Another development is the usage of small surgical instruments for performing the procedure, where the goal is to cut as little as possible, which will minimize the collateral damage and trauma that came with previous surgical procedures that were extremely invasive in nature.

Better Recovery Rate Due To Minimal Invasive Surgical Procedures

The entire point of such a surgery is not to make the cut big enough to fit the instruments, but rather, to use smaller instruments during the procedure that would best fit the cut made. This is the reason why, smaller incisions are used to get access to the knee area after providing local anesthetic to the patient.

One point in favor of the minimal invasive procedure is that, no need is felt to cut the quadriceps tendon or flip the kneecap upside down in order to gain access to the area, which was required in the case of previous surgical techniques. This has also improved the recovery rate far more significantly and at a much faster rate, than old surgical techniques, so now patients are up and about after only 6 weeks of having the procedure done as compared to 3 months.

Cartilage Regeneration Options in Gilbert, Chandler, Mesa AZ

What Is Cartilage Regeneration?

 

Back in the year 2014, a study was carried out by researchers from the Hospital for Special Surgery. They discovered that patients who suffer from cartilage damage in their knee can have it treated with good results, due to the revolutionary technology of cartilage re-generation.knee cartilage defect

The research and a few case studies that followed after the discovery were presented to the American Orthopedic Society for Sports Medicine at its annual meeting held in Chicago that year.

Current Approaches to Cartilage Repair

The name of the tough and incredibly flexible tissue which acts as a cushion for bones and joints is Hyaline Cartilage and it’s this that prevents joints and bones from rubbing against each other during physical activity. Gradual wear and tear or trauma can result in the hyaline cartilage being damaged, which in turn, limits normal joint movement and cause patients to suffer through severe pain. This condition, if left untreated for a long time, can lead to disability.

You should know that damage done to the cartilage isn’t as readily repaired by the body naturally, as the cartilage tissue does not having its own blood supply that would have been otherwise used to bathe damaged tissue and promote cartilage regeneration.

Thus, the current approach of surgeons to effectively treat cartilage damage and help promote its growth is by employing a technique called micro-fracture, a surgery which is generally performed on young adults, who as a result of a sports injury, are suffering from a cartilage tear.

While the procedure promises and gives good results to damage on a smaller scale, micro-fracture is ineffective for those who have widespread cartilage de-generation, or osteoarthritis.

Lighting the Way towards Cartilage Regeneration

Attempts have been made over the years by researchers and orthopedic surgeons alike to build human cartilage outside of the body for years and most of the attempts have proved to be successful, largely due to today’s technological advancements.

The process that is widely used to mimic and grow human cartilage outside of the body involves planting a number of cartilage producing cells into a biological scaffold, then placing them into incubation conditions found in the human body.

There are a number of factors concerned with the effective and successful regeneration of cartilage, one of them being the scaffolds that are being used for the experiment according to Jennifer Elisseeff, director of the Cell and Tissue Engineering Program at John Hopkins University. In her own lab, she uses hydrogel which is a specific type of scaffold.

After spending several years working on creating the highest quality cartilage under lab settings, Elisseeff discovered that the quality of the regenerated cartilage can be influenced for the better if a hydrogel scaffold could be used on the patient following micro-fracture surgery. A series of clinical trials followed the discovery, the results of which were published in Science Translational Medicine.

Clinical Trial Results

The results showed that more of the cartilage defect was filled successfully by the repaired cartilage, i.e. in 86% of the patients, after receiving the special gel/adhesive as compared to 64% who didn’t. Moreover, the cartilage implanted closely resembled the native strains in those who underwent the gel/adhesive treatment following a micro-fracture surgery.
