I had a few emails from people asking for videos of ACL surgery.

I spent some time on YouTube and picked out the best ones I could find.

Here are two.

I hope they help show you what an ACL injury is, how they determine if you have an ACL injury and how they do the ACL surgery.

ACL Injury & Surgery Information

I like this video because there is great information on what the ACL is, causes of an ACL injury, how they test for an ACL injury, how they determine an ACL injury and how they do the ACL surgery.

Risk Factors and Incidence

Basketball ACL Causes of ACL Injuries (Part 5)It is estimated that the overall ACL injury rate in the United States is about 200,000 annually. This figure suggests that 1 in 300,000 individuals in the U.S. will sustain an ACL injury for the first time each year. ACL injuries commonly occur between the ages of 14 and 29 years, occurring in non-athletes and athletes. Those engaged in football, soccer, basketball, soccer and skiing activities are the most susceptible to ACL injury in the athlete group.

Female athletes are more susceptible to ACL injuries than male athletes performing similar sporting activities and training. It is estimated that female athletes are 2 to 8 times more likely to sustain ACL injuries when compared with their male counterparts (Souryal & Adams, 2009).

Many factors have been attributed to the increased susceptibility of women to ACL injuries. Females have a narrower femoral notch, or the space at the bottom of the thigh bone where the ACL runs. This tight fit may cause increased friction between the ACL and femur during knee movements. Another possible cause is the greater Q angle, or the angle between the quadriceps and the patella tendon, in women.  A larger angle is partly caused by a woman’s wider pelvis. This increases the risk for greater stress and ACL injuries. Other factors include increased joint laxity, inadequate strength and impaired neuromuscular coordination.

Anterior Cruciate Ligament Injuries (Part 4)

Filed Under (ACL Injury, Knee Injury, Knee Pain) by Rick Kaselj on 02-09-2010

Here is part 4 of my knee pain and knee injury series.

If you missed part 1, you can see it here. If you missed part 2, you can see it here.  If you missed part 3, you can see it here.

Anterior Cruciate Ligament Injuries: Mechanism of Injury and Causes

The ACL measures between 31 to 35 mm in length and is believed to withstand about 2160 N or almost 500 pounds of pressure before failure or tearing (Weinstein & Buckwalter, 2005). The ACL can also withstand up to 25% of lengthening without failure in younger and healthy adults (Golofski, 2004). Normal activities apply about 454 N or 100 lbs of force on the ACL.

Hyperextension of the knee and the medial rotation of the tibia apply the greatest amount of force on the ACL. These same positions also place the ACL at highest risk for tearing or rupture.  Hyperextension of the knee is the excessive straightening of the knee that forces the tibia excessively forward in relation to the femur. Medial rotation of the tibia is the excessive inward turning of the tibia.

Muscles

Illu lower extremity muscles 240x300 Knee Injury Ligaments (Part 3)The movements and the stabilization of the knee joint are supported by the quadriceps and the hamstrings. The quadriceps is actually composed of four individual muscles located on the anterior upper leg. These muscles are the vastus lateralis, vastus medialis, vastus intermedius and rectus femoris. These muscles fuse, forming the quadriceps tendon. The quadriceps straightens the knee by pulling the patella up on contraction.

The hamstrings are the muscles that attach to the tibia, specifically at the back of the knee. It consists of three individual muscles: biceps femoris, semitendinosus and semimembranosus. The hamstrings functions by flexing or bending the knee joint. This muscle group also provides stability on both sides of the knee.

Ligaments

The stability of the knee largely depends on the four major knee ligaments: the medial collateral ligament, lateral collateral ligament, anterior cruciate ligament and posterior cruciate ligament. Ligaments are the tough but slightly elastic bands of connective tissues that hold two or more bones together. Excessive movements, such as hyperextension or hyperflexion, at the knee joint are restrained by these ligaments, stabilizing the knee joint and keeping the bones in their correct alignment during movements.

Medial and lateral collateral ligament

The medial collateral ligament, or MCL, resists excessive forces coming from the knee’s outer surface, or valgus forces. The lateral collateral ligament, or LCL, resists the forces coming from the inner surface of the knee, or varus forces. These ligaments are located on the outside of the knee joint and are able to heal on their own.

Anatomy of Knee Pain (Part 2)

Here is part 2 of my knee pain and knee injury series.

If you missed part 1, you can see it here.

Anatomy of the Knee cont.

Lower Leg Bones 300x296 Anatomy of Knee Pain (Part 2)Next to the femur, the tibia is the largest bone in the body. It is the weight bearing bone of the lower leg. The upper end of the tibia joins with the femur and its lower end joins with the talus, the bone that forms the lower part of the ankle. The fibula is located on the outer side of the leg. Unlike the tibia, this bone is non-weight bearing. Instead, it functions as an ankle joint stabilizer and as an attachment site for one of the four major knee ligaments and the biceps femoris tendon. The lower end of the fibula protrudes on the lateral side of the ankle.

Patella

The patella, also known as the kneecap, protects the knee joint. It holds the quadriceps tendon on the lower end of the femur, acting as a fulcrum for the quadriceps muscles. The quadriceps is a group of four individual muscles on the anterior part of the thigh. The lower patella connects to the tibia through the patellar tendon.

Menisci

Incompletely covering the surface of the tibia that joins with the femur are the C-shaped fibrocartilages known as the medial and lateral menisci. The menisci function as shock absorbers that equally spread the weight of the body, reducing friction between the tibia and the femur during knee movements. They assist in knee rotation and play a function in stabilizing the ligaments.

I have got a lot of great feedback from my last post on knee pain, knee injuries and ACL injuries.

If you missed it, you can check it out here.

Overview of Knee Pain

Knee Pain Exercise 225x300 Overview of Knee Pain (Part 1)The knee is the largest joint in the human body. In the most recent report of the U.S. Department of Health and Human Services, the knee is also one of the most commonly injured joints. Each year, more than 5.5 million orthopaedic visits are made due to knee injuries. The joint’s high susceptibility to injuries is mainly attributed to its intrinsic anatomical structure and its function during weight-bearing. Moreover, because of the increasing problem of obesity and a sedentary lifestyle, knee injuries are one of the leading causes of disability in modern society.

Knee injuries are complex because they typically involve more than damaged structure. The anterior cruciate ligament, the major stabilizing ligament of the knee, is frequently the cause of knee pain and injury in young, healthy adults. ACL injuries can be devastating. A significant number of patients with ACL injuries require reconstruction, prolonged rehabilitation and as a result, high health care costs. For these reasons, ACL injury prevention has been the focus of many researchers over the last few decades.

Neuromusclar training programs consisting of specialized stretching and strengthening exercises of the knee’s dynamic stabilizers, agility training and plyometrics have been found to be the most effective strategies to prevent anterior cruciate ligament injuries. These exercise programs are designed to help clients regain and maintain the functions of the knee without putting much force on the ACL. Some of these exercises are introduced in the last section of this guide.

ACL Injuries in Female Athletes

ACL Injuries in Females

NASA knee brace ACL Injuries in Female AthletesOver the last decade, torn and ruptured anterior cruciate ligament (ACL) in female athletes have increased at an alarming rate.

Consistently, it has been found that a higher prevalence of ACL injuries occurs in female athletes over their male counterparts.  Women are 2.4 to 9.7 times more likely to suffer from ACL injury when compared to men of similar competition and training levels.

Females involved in sports involving landing from a jump, abrupt changing of directions and cutting, such as basketball, soccer, gymnastics, skiing and gymnastics are especially at risk. Reports state that women basketball players are 5 to 7 times more likely to have an ACL injuries than men and that female soccer players are injured more than twice as often as men (American Council on Exercise, 2009). On average, women rupture their ACL ligaments 5 years earlier than men do. In addition, majority of females with torn ACLs are between the ages of 15 and 25.

Although the exact cause is still unclear, and the possibility of a complex interplay between different factors is likely, possible explanations of the gender difference in the rate of ACL injuries have been suggest and reviewed. The suggested reasons are anatomic differences, joint laxity, range of motion, hormonal secretion and training techniques are suggested factors that predispose women to ACL injuries.

There are two different factors that can influence an injury.  The first is intrinsic factors.  Intrinsic factors are internal factors with the body that can increase the risk of injury.

ACL Survey Results

January 2009 – OrthoSupersite -  Thomas R. Duquin, MD; William M. Wind, MD; Marc S. Fineberg, MD; Robert J. Smolinski, MD; Cathy M. Buyea, MS

In 2006, a survey regarding anterior cruciate ligament (ACL) reconstruction was mailed to physician members of the American Orthopaedic Society for Sports Medicine. A total of 993 responses were received from 1747 possible respondents (57%). The number of ACL reconstructions per year ranged from 1 to 275 (mean = 55). The most important factors in the timing of surgery were knee range of motion and effusion. Bone-patellar tendon-bone (BPTB) autograft was most commonly preferred (46%), followed by hamstring tendon autograft (32%) and allografts (22%). Five years earlier, BPTB grafts were more frequent and hamstring tendon and allografts were less frequent (63%, 25%, and 12%, respectively). A single-incision arthroscopic technique was used by 90%. Most allowed return to full activity at 5 to 6 months, with a trend toward earlier return for BPTB grafts; quadriceps strength was an important factor in the decision. There was limited experience (4%) with double-bundle and computer-assisted ACL reconstruction.
