Quad extensions after acl surgery, how to lose 10 percent body fat in 2 weeks - Within Minutes

Author: admin
Skiers usually injure the ACL when they catch the inside edge of a ski on ice, causing them to lose control and fall backwards as they hyperflex the knee. Once the athlete is diagnosed with an ACL injury, the first step is to decide whether to undergo surgery to reconstruct the torn ligament, or to rehabilitate the knee without surgery. Rehabilitation after ACL reconstruction surgery should initially focus on decreasing inflammation and restoring normal range of motion. Restoring full range of motion of the injured knee, particularly in extension, should be a priority in the first two weeks post-surgery. The continuous passive motion machine (CPM), an electrical motor-driven device, may be used in the hospital immediately following recovery from surgery. After the patient is released from the hospital, a specific series of exercises (provided by a trained therapist) should be done as often as possible to restore full range of motion of the knee in extension. Towel stretch extension exercises (Figure 4C) can be incorporated if the above exercises are not restoring extension appropriately.
A normal gait cycle depends on a person’s ability to lock the knee in full extension while weight bearing. The goals of the first two weeks of post-operational rehabilitation are to reduce swelling, restore full range of motion in extension and flexion, ambulate without the use of crutches, and sit down and stand from a seated position.
According to Bill Knowles, director of iSPORT at the Vermont Orthopaedic Clinic in Rutland, Vermont, after ACL repair, the sutures are usually removed between ten days and two weeks post surgery. After 115 degrees of leg flexion is attained, stationary cycling can commence to increase range of motion of the knee joint, as well as provide light endurance exercise. Continue towel stretches and Flexband® stretches to maintain and increase range of motion of the knee in both flexion and extension.
The patient can return to full light sport participation if assuming full range of motion, 90 percent strength of the hamstrings and quadriceps musculature (as compared to the healthy leg) and success in conducting all of the agility drills with no pain or swelling.
Treatment of the repaired ACL at this office would commence after the sutures are removed and the wound is healed, approximately two weeks post-surgery.
ACL reconstructive surgery would be recommended for athletes who continue to suffer from repetitive bouts of the knee giving away, or for those athletes who want to return to a highly competitive sport level.
The most important goals in the first two weeks are to reduce swelling and restore full range of motion of the knee in extension and flexion. The surgeon selects the appropriate type of surgery based on the patient’s sport and the movements most frequently used. At two weeks post surgery there was still no continuity between the graft tendon and the insertion point in the bone.


After the first week of post-operative rehabilitation, the patient should be able to fully extend the leg and flex the leg to 110 degrees.
Passive extensions (Figure 4A) and weighted extensions and prone leg hangs (Figure 4B) are useful exercises for restoring extension of the knee. These pads are secured by ropes passing through a ratchet system that would be tightened to force the knee into full extension (Figure 4D).
Surgical reconstruction of the ACL restores the check-rein function of the ligament by preventing excessive forward movement of the tibia on the femur.
Two exercises that are instrumental in returning coordinated strength to the leg are isometric co-contractions of the hamstring and quadriceps musculature, and the other is properly performed quarter squats and full chair squats.
ACL injuries commonly occur in athletes participating in sports such as football, basketball, soccer, and volleyball, where movements such as cutting, pivoting, single leg landing and rapid decelerations are routinely performed.
Examination of the knee may reveal extensive swelling around the knee joint, loss of full extension of the knee and an inability of the athlete to bear weight on the injured leg.
Athletes deciding not to have reconstructive surgery may be able to return to an active lifestyle after completing a rehabilitation program; however, they must learn to modify their activities to accommodate for the compromised stability of the knee due to the lost check-rein function of the ACL. The pre-operative rehabilitation phase prepares the patient physically and mentally for both the surgery and the postoperative rehabilitation program.
The selected graft tissue would be surgically placed in the anatomical location of the previous ACL and then secured by interference screws. At this point, full extension is the most important goal; flexion of the knee improves steadily as swelling around the knee joint decreases. The CPM supports the leg while moving it from full extension to a progressively set degree of flexion. During passive extensions, the patient can lie on the back with the heel propped up on pillows.
The patient then raises the heel off of the ground to bring the knee into extension while placing the other hand on the thigh to stabilize the leg. Post-surgery rehabilitation depends on restoring the function of these dynamic restraints, with the main focus on restoring flexibility and strength to the hamstring and quadriceps musculature. Tearing of the ACL is most commonly caused by landing awkwardly or cutting on a fully extended or slightly flexed leg with the foot turned outward (Figure 2). If full extension of the knee is not restored within two weeks post-surgery, scar tissue may develop in the joint, preventing the restoration of full knee extension. There is a ten-second pause at the end of each movement, during which time the patient will isometrically contract the quadriceps (front thigh muscles).


Once the leg is relaxed in extension, the patient can periodically contract the quadricep musculature to push the knee further into extension. However, full functional rehabilitation of the reconstructed ACL may not occur until six to 12 months post-operatively.
After 12 weeks the tendon graft was safely secured to the surrounding bone, at which point failure of the graft-insertion point was minimal. The patient then holds the quadracep contraction for five seconds, then returns to relaxed extension. A straight leg raise is an example of an isometric strength training exercise for the quadriceps musculature.
Correct technique of step-downs is necessary for the patient to maintain hip stabilization, prevent pelvis drop, and proper cocontraction of the hamstring and quadriceps musculature of the injured leg to achieve a controlled leg flexion as the other foot touches the ground surface.
As the patient squats down, the quadriceps musculature fires to decelerate flexion of the leg, while the hamstring and gluteus musculature fire to decelerate the pelvis from rotating forward. If extension is not achieved this way, the patient may progress to weighted extension exercises by placing a five to ten pound weight just above the knee and following a similar procedure as passive extensions. The hamstring musculature also aids the reconstructed ACL in its check-rein function on the tibia. The step-down height can be increased to four, six, and eventually eight inches as the patient regains motor control of the hip stabilizers, gluteus and hamstring musculature, as well as the decelerator of leg flexion, the quadriceps musculature. Proprioception training will increase the state of readiness of the knee joint, decreasing the chance of re-injuring the ACL upon return to sport.
These exercises are crucial in developing the coordinated muscular activity of the hamstring, gluteus and quadriceps musculature that is necessary for a normal walking gait during full weight-bearing on a flat surface, as well as walking up and down stairs and getting into a seated position. An example of a concentric strengthening exercise would be forward stepups, whereby the quadriceps would concentrically contract to force the leg to extend.
Have the patient lie on the stomach with the knee just past the edge of the table or bench with the knee in full extension; use a weight if struggling with full extension.
Rehabilitation of the dynamic restraints will aid in taking stress off of the repaired ACL, preventing re-injury.
