Can Patellar Resurfacing Prevent Anterior Knee Pain
The necessity for patellar resurfacing in TKA is discussed extensively in the literature . Fu et al. conducted a meta-analysis of the efficacy of patellar resurfacing in TKA ten studies with 1,003 TKA were included. In this study there was no difference in the incidence of anterior knee pain. The risk for reoperation, however, was lower in the resurfacing group than in the group without resurfacing. Similar results were published by He et al. . This meta-analysis included 16 studies with more than 3,000 knee joints. There was no difference between the two groups in terms of anterior knee pain rate, knee pain score, Knee Society knee score and function. The incidence of reoperations in patients without resurfacing was lower than in patients with resurfacing . When only high-quality studies were analysed, there was no difference in reoperation rates between the two groups. From these results, no clear recommendation can currently be made regarding the need for patellar resurfacing regarding the prevention of anterior knee pain.
What Causes Tight Tibialis Anterior Muscles
Tight anterior tibialis muscles can be rather annoying as it makes the simple task of walking unpleasant. The causes of tight tibialis anterior can lead to shin splints and can be a result of any of the following:
- Direct trauma to the muscle area
- Intense workouts or prolonged workouts where your ankle is constantly flexed upwards
- Running, jumping or other high impact activities on hard surfaces
- Imbalance gait while walking or running
- Sudden change in exercise routine
Area : Medial And Lateral Knee Pain
Thomas McDaniel / Immediate Media
Pain at the sides of the knees is fairly common and the culprits here are almost always the feet, or more specifically, incorrectly fitted pedal cleats.
To this end, such pain is often noticed during or after the rst ever ride with cleats, or with a new pair of shoes or replacement cleats.
The structures causing the pain are most often the collateral ligaments, which sit on the outsides of the knee joint, stopping them from bending the wrong way.
- Bike-specic problems are usually to blame here: badly placed cleats will either affect the Q angle or cause excessive rotation of the knee joint, stressing one or other of the collaterals. The Cleat Position and Knee Pain diagram describes the usual culprits and what to do with them.
2 ways to avoid and treat medial and lateral knee pain when cycling
- Check cleats for excessive wear regularly. Always make sure you draw round cleats with a felt tip pen to mark position before replacing them, and experiment with different cleat types until you nd one with the right amount of oat for you .
- Get off on the right foot. If youre new to cleats, one tip for getting a good starting position is to sit on the edge of a table with hips, knees and ankles relaxed at 90 degrees. Look down: whatever angle your feet naturally dangle at should be replicated by the cleats.

How Long Does It Take To Fix Anterior Pelvic Tilt
Its impossible to say. If its a genetic trait, you may not be able to make a permanent change.
But you can fix movement patterns. The more you focus on changing the way you sit, the way you stand, and the way you do key exercises, the faster and more permanently you can change the effects of anterior pelvic tilt.
Thus, while the anatomical change may be minimal, you can keep it from becoming dysfunctional and minimize the risk of injury.

Osteoarthritis Of The Knee
Osteoarthritis is a common cause of knee pain and usually affects people over fifty years old. It occurs when cartilage which protects the bones degenerates. Symptoms include:
- Knee pain which develops gradually over time.
- Initially, thie may be a deep, aching pain in the inner knee.
- Pain is worse after exercise.
- You are likely to have stiffness and sometimes swelling in the joint.
- Sometimes a clicking or cracking noises are heard when moving your knee.

Why Would A Teenager Have Knee Pain
Knee pain isnt a condition that only happens to older people. Despite being young, your teenager can develop knee pain too.
Knee pain in teens is a common result of overuse, but also results from specific knee injuries and medical conditions that affect the knee. Knee pain can also be temporary and not related to an injury, but rather a change in your teens level of activity or sport.
Because of the many different reasons for knee pain, if your teen complains of pain, its wise to get it checked. Never think that knee pain in your teen is simply growing pains. This is not a typical cause of knee pain in a teenager.

What Is Tibialis Anterior Tendinopathy
Tibialis anterior pain refers to swelling within the anterior tibialis tendon.
The injury is caused either by overuse or traumatic ankle injury.
But whats the anterior tibialis tendon in the first place?
Time for anatomy 101.
The lower leg is made of four compartments that separate and contain the muscles located within the knee to the ankle.
The four compartments include:
- Deep Posterior , and
- Superficial Posterior
The tibia and fibula , the anterior intermuscular septum, and the interosseous membrane are the borders of the compartments.
What Is Anterior Pelvic Tilt And Why Its Bad For You
An anterior pelvic tilt means that your pelvis is rotated forward. The forward positioning of your pelvis forces the curve in your lower back to adopt a more extended position, known as hyperlordosis.
This posture is sometimes referred to as the Donald Duck posture!
Not only is an anterior pelvic tilt unsightly, it can lead to a variety of problems, including:
- Increased pressure on spinal vertebrae, which can lead to facet joint irritation, stress fractures, increasedintervertebral disc pressure, and disc degeneration.
- Chronic pain of the back, hips, knees, and ankles
- Sciatica symptoms

Offset Errors Of The Femoral Component
The anterior offset of the femoral component has a major impact on the mechanics of the patellofemoral joint. An anterior overhang can be caused by selection of a femoral component that is too large or an overly minimal anterior resection . This can lead to increased pressure of the patella and its surrounding structures .
However, an increased anterior resection can also lead to patellofemoral problems. In this case, the passive quadriceps insufficiency may be a cause of anterior knee pain. Increased posterior offset can also lead to flexion deficit which might also influence the contact pressure in the femoropatellar joint.
Functional Causes Of Anterior Knee Pain After Tka
Most patellofemoral complaints are mild to moderate and do not require any revision . Many of these problems have no structural but a functional cause and may be related to preoperative osteoarthritis.
It is well known that a preoperative weakness of the quadriceps muscle may persist after TKA. This weakness has significant influence on the movement pattern of the knee . It is also known that imbalance of the quadriceps with weakness of the vastus medialis and increased activation of the vastus lateralis muscle can cause a lateral maltracking of the patella . The preoperative quadriceps weakness caused by osteoarthritis may further deteriorate due to the implantation of a total knee replacement and it may take more than two years until the power of the contralateral limb is reached .
Patients with osteoarthritis of the knee often present with additional osteoarthritis of the hip . The weakness of the hip abductors and external rotators can lead to dynamic valgus . If the functional disorder of the hip abductors is caused by osteoarthritis, osteoarthritis of the hip should be treated. Sled et al. , however, have shown that patients with knee osteoarthritis profit from training the hip abductors.
Dynamic valgus affects the femoropatellar joint because it leads to lateral patellar maltracking . Dynamic valgus or functional malalignment can be clinically detected with the single leg squat .

Can Someone With Pfp Syndrome Play Sports
Most people with PFP syndrome need to cut back or stop sports for some time. Follow the health care provider’s instructions on when it’s safe for you to go back to sports. This usually is when:
- Hip, leg, and core strength is near normal.
- Flexibility, especially in the hamstring muscle, has improved.
- There’s no pain with everyday activities, such as walking and going up/down stairs.
- Any pain with activity is very mild and goes away within a few minutes of starting the activity.
Exercise : Standing Pelvic Tilts
Here, you want to repeat the previously discussed exercise in the standing position. The exercise is now less controlled. You no longer have the support and stability gained by performing the exercise on the ground. Despite this change, the movement is nearly identical. Mastering exercise 1 will allow you to perform exercise 2 with much greater ease.
Exercise 2 is shown with the top picture showing the anterior pelvic tilted position and the bottom picture showing the posterior tilted pelvic position. The blue arrows indicate the direction of movement of the lower back and glutes in the picture.
The backward movement of the lower back and tilting of the pelvic girdle in the posterior direction will move you from the anterior to the posterior tilted position. The opposite movement will then return the body to the anterior tilted position. You can repeat this movement multiple times to attain the desired results. You can do so throughout the day or on successive days if you like.

Lower Iliotibial Band Stretch
Lie on your good side, in a straight line along the edge of a bed so youre looking across the bed.
Hold on to the end of the bed with your lower arm for support.
Reach behind you with your upper arm and pull your foot to your bottom, as if you were doing a regular quads stretch. Keeping your foot against your bottom, gently increase the quads stretch by pulling your leg backwards. Youll feel it along the front of your thigh let yourself relax into this stretch.
Still holding this stretch, and making sure you dont tilt your hips backwards, now very gently push your knee down towards the floor.
At a certain point you should feel quite a sharp stretch down near the knee perfect for lengthening those tight soft tissues around the lateral aspect of the patella. Its important to keep your whole body in line and perpendicular to the bed during the stretch.
If youre lucky enough to be able to enlist the help of a patient friend, then ask them to place one hand on your hips and push down very gently! on your knee with the other. This produces a better stretch, since you can completely relax the leg as its being pushed down.
Emphasize Spinal Alignment On Deadlifts Squats Presses And Other Compound Lifts
With most clients, arch your back is a useful cue for deadlifts and other hip-dominant exercises. Same with exercises in which clients are likely to round their backs, like box squats.
But telling someone with anterior pelvic tilt to arch can do more harm than good. The lumbar curve is already exaggerated, especially on deadlifts, when someone with APT might arch his back throughout the entire lift. That increases the risk for spinal damage.
And the deadlift is just one problematic exercise for a client with anterior pelvic tilt. You may see swayback on overhead presses and pulldowns. A quad-dominant client with poor glute activation could struggle with squats, and her poor technique could set her up for injuries.

On both squats and deadlifts, the two cues that work best for me are spread the floor apartthat is, push against the outside of the feetand drive through your heels. You also want to assess the clients technique with a side view, paying close attention to the bars trajectory. It should travel in a vertical line over the midfoot, with the spine in neutral alignment.

Basic Knee Anatomy & How It Functions During Deadlifts
Lets briefly cover the anatomy.
The knee joint contains four bones which are the: femur, tibia, patella, and fibula.
The thigh bone is broken up into the medial and lateral condyles, which are the edges that sit on top of the shin bone .
Both the thigh bone and shin bone are lined with shock-absorbing cartilage which includes the lateral and medial meniscus.
The knee also has ligaments across both the femur and tibia that provide stability with:
The knee cap is a bone that is a part of the quadriceps tendon that sits in a groove on top of the femur and is also connected to the tibia through the patellar tendon.
There is a common misconception that the knee is just a hinged joint that bends and straightens . Its actual motion is much more complex due to the contours of the medial and lateral femoral condyles, which are oval-shaped and not rounded when they sit on top of the shin bone . Due to this shape, the knee joint also has a small degree of inside and outside rotation as well.

What Are The Symptoms Of Patellofemoral Pain
- Pain around the knee. The pain is felt at the front of the knee, around or behind the kneecap . Often, the exact site of the pain cannot be pinpointed instead the pain is felt vaguely at the front of the knee.
- The pain comes and goes.
- Both knees are often affected at the same time but one is usually worse than the other.
- The pain is typically worse when going up or, in particular, going down stairs.
- Running, especially downhill, squatting and certain sports can all set it off – anything that leads to the patella being compressed against the lower part of the thighbone.
- The pain may be brought on by sitting still for long periods. For example, after going to the cinema or for a long drive, when it will be worse when starting to move about again.
- There may be a grating or grinding feeling or a noise when the knee bends and straightens. This is called crepitus.
- Sometimes there is puffiness or swelling around the kneecap.
Does Anterior Pelvic Tilt Cause Tight Hamstrings
Possibly. Muscles that are chronically lengthened will tend to be tight, whether theyre strong or weak. If a muscle is already stretched, its going to reach maximum tension sooner than a muscle without that handicap.
But heres a riddle: If the hamstrings are tight, why dont they pull the pelvis down into a neutral position?
The answer, as Mike Reinold explains here, is that the hamstrings may be fine. But because APT shifts the top of the pelvis forward, and the hamstrings are attached to the bottom of the pelvis, they have to start any movement from a suboptimal position, even if theyre capable of an optimal range of motion.
Again, this all happens in degrees.
