Utilize The Powers Of Electrical Stimulation
Neuromuscular electrical stimulation appears to be a promising intervention for use after ACLR. NMES allows for the direct activation of the motor axon, and could allow for the direct recruitment of the inhibited motoneurons. Muscle activation by means of NMES allows for the recruitment of a greater proportion of type II muscle fibers when compared with voluntary contractions of a similar intensity.- Furthermore, although, during voluntary contractions there is a logical order of recruitment beginning with the smallest motor units and progressing to the largest motor units, NMES results in a reversal of the order of motor unit recruitment. The activation of type II motor units are essential to achieve a higher level of quadriceps force production, as well as sufficient power and RFD. As such, their recruitment by means of NMES undoubtedly should aid in the quest to achieve complete recovery of quadriceps strength. A recent meta-analysis reported that use of NMES in addition to standard physical therapy appears to significantly improve quadriceps strength and physical function in the early post-operative period compared to standard physical therapy alone.
Focus On Your Whole Knee
The quadriceps may be the bodys natural knee brace, as the study authors referred to them, but theyre not the only muscles that are critical for good knee function. Equally important are the hamstrings on the back of your thigh and the gluteal muscles of the buttocks. Like the quadriceps, these muscles not only help you sit and rise from a seated position, but they also enable you to complete other everyday activities. These include climbing stairs, lifting heavy objects and getting into and out of your vehicle.
Unfortunately, many people tend to focus on increasing quad strength and flexibility, at the expense of their hamstrings and gluteal muscles, Bungo says. We see that a lot, and that creates a muscle imbalance, which can predispose you to injury. Its important to have that balance.
Several complications can arise from having weakness or poor flexibility in your quads, hamstrings and gluteal muscles. For instance, you might alter your gait to compensate for these deficiencies, and in doing so, you can put stress on other parts of your body, such as your hips and lower back. Plus, poor leg strength can impair your balance and increase your risk of debilitating falls.
Balance is a combination of lower-body strength and your sense of balance, Bungo explains. Knee weakness, and lower-extremity weakness in general, absolutely can increase your fall risk.
Think Beyond The Knee
Typically, early and mid-phase programs focus exclusively on resolving knee mechanics. It is becoming accepted that weakness of core and hip muscles are risk factors in lower extremity injury risk- and in particular ACL injuries., A systematic review by Petersen et al. revealed deficits in hip muscle strength after ACLR. Beyond injury prevention, proximal dysfunction is associated with high risk movement biomechanics and linked to PFP., Strong evidence currently exists that patients with anterior knee pain have deficits in hip abduction, hip extension and external rotation strength. Hip muscle strengthening is effective in reducing the intensity of pain and improving functional capabilities in patients with PFP and should form part of the ACLR rehabilitative program focused on resolving knee extensor strength deficits.

Exercise #: Stationary Bike And Elliptical Machine
These cardiovascular exercises are especially beneficial because they help strengthen the quadriceps muscles, says Geller. This is particularly important after a knee replacement because the quads are essential to movement and stability in the knee. “These exercises are non-impact, which is safer for your knees than high-impact exercises like running,” says Geller. Bill Bryan, MD, an orthopedic surgeon at Houston Methodist adds that when he tells patients who’ve had a knee replacement to use the stationary bike, he recommends that they push down harder on the pedal with the leg that’s had the knee replacement. “This will maximize the benefits of this exercise,” says Bryan.
The Best Leg Strengthening Exercises After Surgery
After surgery to the hip, knee, ankle, or foot, the muscles of the leg often become weak from decreased use during recovery. For this reason, it is important to begin strengthening these muscles once your physician gives you the green light to do so.
Gaining back strength that you have lost after an injury or after surgery is an important step in obtaining full functional mobility and a full recovery.

What Is Quad Activation Failure
Quad activation failure is the inability to squeeze or tighten your quadriceps. Its not uncommon after major surgeries like an ACL surgery or a total joint replacement but can occur even with arthroscopy.
The frequency is highly variable, but full quad shutdown occurs in less than 5% of post-operative knee patients, said Dr. Farr.
Quad shutdown is caused by neural inhibition which means the nervous system isnt allowing the normal pathways of muscle activation to happen.
After knee surgery, the knee swells up which leads to arthrogenic muscle inhibition, which is having the inability to contract your muscle despite no injury to the muscle or nerve.
In fact,years ago, according to a study, researchers injected saltwater into the knee joint of volunteers,said Dr.Farr. Whenthe volunteershad knee fluid distention , they were unable to fullyactivate their quadriceps.This quadriceps restriction may beamplified with pain, the fear of increasing the pain or even partial weakness from a nerve blockperformed at the time of surgery.
To reverse this after knee surgery, you will need to re-establish a brain-muscle connection and retrain your muscle to contract properly.
Return To Sport And Normal Function
It is possible to get ACL knee strength back in the first year after surgery and to pass return-to-sport criteria and achieve normal function, says Claussen.
Key elements in Shelbourne Knee Center ACL rehab model are:
- Restoring ROM prior to strengthening
- Using a contralateral PTG, which provides a predictable return to normal strength in both knees.

What Not To Do:
- Do not lock the knees during this exercise. The knees should remain slightly bent.
- Do not allow any part of the stepping foot to hang off the stool or platform.
- People who have issues with balance should not perform this exercise.
Muscles involved: Quadriceps, hamstrings, and gluteal muscles.
There are many different ways to stretch the hamstrings in the back of the legs. One is through traditional toe touching.
- With the feet close together, slowly bend over at the hips and extend the arms downward. Keep the legs straight but do not lock the knees.
- Reach the fingers to the top of the toes and hold for 30 seconds.
- Initially, it may not be possible to reach the toes. In this case, try to get the fingers as close as possible to the toes without causing pain.
What not to do:
- Do not use a bouncing motion. Hold the body still.
Benefits Of Knee Strengthening Exercises
The Arthritis Foundation state that exercise may be the most effective way to treat osteoarthritis without surgery, while the American Academy of Orthopaedic Surgeons note that strong and flexible muscles can keep knees healthy and prevent injury.
Knee strengthening exercises do not affect the knee joint directly, but they strengthen the muscles surrounding it. Strong muscles in the legs can help provide support for the knees. This support may alleviate pressure and strain on these joints, which can relieve pain and help a person be more active.
The following exercises can help strengthen the muscles surrounding the knee. If a person experiences pain during these exercises, they should stop doing them and speak to a doctor. Anyone with severe knee pain should consult a doctor before trying to exercise.
It is best to warm up with light exercise before starting any knee strengthening exercises. Examples of gentle exercise include walking, cycling, and using an elliptical machine, all of which put minimal stress on the knees. This activity will help increase blood flow to the muscles and allow them to be more flexible.
Muscles involved: Quadriceps and abdominal muscles.

Optimally Prepare For Surgery
Optimally preparing for surgery and resolving deficits in muscle mass and strength would be expected to enhance post-operative function. The research available indicates that prehabilitation results in superior knee function post operatively.- Recent research shows that patients with better pre-operative quadriceps activation demonstrated greater post-operative activation, whilst patients with better pre-operative strength also demonstrated better post-operative strength. There is no consensus on the optimal level of pre-surgery function. Grindem et al. recommended patients should have a LSI of 90% for muscle strength and hop performance prior to ACL reconstruction, which may not be plausible for all patients.
Sit To Stand Quad Exercises
Standing up from sitting is a movement we do countless times a day but actually works the quadriceps muscles quite hard.

Open Chain Or Closed Chain Isolated Or Functional
There is no consensus among the existing published evidence as to whether closed kinetic chain or open kinetic chain exercises should be the intervention of choice following ACLR. There are doubts about safety of OKC exercises, which are arguably unsupported by substantial published evidence. OKC exercises can be useful as they isolate the muscle and limit the involvement of other muscle groups and thus, can ensure higher and more complete activation and fatigue of the target muscle. Some studies have shown that OKC exercises or OKC plus CKC exercises are more effective than CKC exercises alone in improving quadriceps strength after ACL reconstruction, and in patients who are ACL deficient. Others have found no differences in patients quadriceps strength when comparing the two types of exercises., Available clinical research suggests that cautiously incorporating OKC exercises into ACL rehabilitation will improve quadriceps function and the authors advocate the use of both OKC and CKC exercise.

Optimal Load To Preserve Quadriceps Strength
Optimal loading may be defined as the load applied to structures that maximizes physiological adaptation. Additionally, in the context after injury, it can also be considered as the load which minimizes adaptation .
Achieving optimal loading is challenging. It is essential that in the early periods after surgery, the rehabilitation program incorporates progressive optimal loading to prevent muscle atrophy and strength loss and subsequently facilitate functional recovery. Use of electrical stimulation can support strength preservation, through providing a stimulus to activate the motor units, which may be inhibited due to AMI. The use of electrical stimulation and voluntary isometric contractions can support muscle mass and strength preservation in the early phase. Monitoring pain and joint effusion particularly during the early phases of rehabilitation are important to ensure that the applied training stimulus is not excessive and causing tissue overload. Measurement of pain via the use of the visual analog scale should be taken regularly and recorded. Swelling can be measured with limb girth daily. Measurement of knee circumference at the patella has been shown to have strong intra-tester reliability and good sensitivity to change. Within, the knee, change greater than one centimeter was shown to be clinically significant.

Tips To A Speedy And Successful Rehabilitation
- Apply ice for 10 15 minutes to the operated knee after exercise. Using cold therapy while elevating the leg above your heart helps reduce swelling
- Beginning 3-4 days after surgery, you can also apply heat under the knee or to the thigh muscle well above the incision for 10-15 minutes before you exercise
- Short arc quad exercise helps improve strength and range of motion in the knee. Lie on your back with your legs extended and the knee supported by a rolled towel or foam roller. Keeping the knee on the roller, straighten the operated leg at the knee by lifting the heel off the floor. Hold for 5 seconds, then slowly lower the heel back down
As you recover in the hospital, a physical therapist will most likely teach you exercises to help strengthen your knee. Most often, you can begin these exercises the day after your operation. It is highly recommended you stretch and exercise daily to help avoid complications or dislocation of your new joint.

Get Up And Get Moving
After a knee replacement, the patient is strongly encouraged to get up and move almost as soon as the anesthesia wears off. Early mobility is key to the prevention of blood clots, which is a risk of lower extremity surgery. Getting up and moving is also crucial in reducing swelling, which will hinder range of motion.
