4 factors that contribute to the kneecap dislocation
www.PTcares.com

Kneecap is a bone in the front part of the knee joint, also is known as the patella. Many young athletes have dislocation accidents followed by pain, swelling, and significant functional limitations. My friend's 18 years old son, Tom, has been diagnosed with Patellar Femoral (PF) joint dislocation. As a bike-riding lover, Tom was sad to be told by his PCP to stop the biking for 3 weeks after the accident. He had X-ray done and was suggested to go to see an Orthopedic surgeon for suggestions and see an experienced PT for quadriceps training.  Tom's mother asked me this question, "Why and how to deal with the kneecap dislocation?"

So today I will share with your the 4 factors that contribute to the kneecap dislocation.
1. The shape of the distal femur bone. There is a groove in the distal femur bone that accepts the kneecap while the joint is moving into flexion or extension. When the shape of the groove is too shallow or one side of the groove is not well developed, it is very easy for the kneecap to pop outside of the groove.
2. The weakness of the distal quadriceps muscle. The kneecap was supported externally by distal quadriceps muscle. Without the protection of the muscle, the surrounded soft tissues will be pulled and eventually cannot hold the bone in the right position anymore.
3. Wrong alignment of the legs. When the hip internal rotators are too tight and/or the foot is pronated, the knee will end up with increased valgus. Medial side of the knee will be stretched and the kneecap will be pulled toward lateral side.
4. Wrong dynamic control of the knee with landing after jumping. A habit of too much inward shifting of the knee with landing was very common for young athletes especially the female athletes.

Now we know the kneecap dislocation is related to the above 4 factors. How to prevent it then?
My recommendation will be:
1. Work on the distal quads muscles
2. Pay attention to the alignment of the leg with workouts and other activities
3. Motor control training to improve the landing technique
4. Get an X-ray of Axilla View of the knee, talk to your PCP or Orthopedics.

Well, here you have it. The 4 factors related to the kneecap dislocation and treatment strategy.

Dry Needling by a Physical Therapist: What You Should Know

Dry Needling by a Physical Therapist: What You Should Know I got questions about DN a lot recently. So here is a useful link to learn about Dry needling. https://www.moveforwardpt.com/Resources/Detail/dry-needling-by-physical-therapist-what-you-should A licensed PT with DN training will help you to deal with tightness, pain, and headache. My personal feeling about Dry Needling was not as great at the very beginning, mainly because of the limited evidence we have now.  But after seeing the change of my clients after DN, I recommend DN to all providers and clients. The baseline is the anatomy. Now I see the DN technique as a new approach to get to the deep and sensitive muscles. Usually, I will have to do a lot stretching and adjustment of the spine before the "angry tissues" will relax. That means more pain during the process and less compliant with my client. Now with DN approach, I can pinpoint the compensated tissues quickly. I mean genuinely PINPOINT ...

A true case of neck herniation presentation

"Surgery, or not surgery?" Recently one of my clients had to make the biggest decision of her life. She will have to make up her mind and accept a fusion surgery on the cervical spine. The risk of paralysis with or without surgery is the biggest concern for her, not to mention the risk of infection, active bleeding and possibly expensive medical bills. Her MRI did show spinal stenosis with 4 intervertebral disks herniations, which match the constant spasm and very limited range of the neck and shoulders. She started to notice the weakness of the legs with mild tripping imbalance accidents. She almost cried when we talked about the possible surgery before further rehab. Constant spasm with tingling of the limbs usually indicates some impinging problem of the peripheral nerves close to the spine.  I strongly suggest anyone with a similar presentation go for professional help immediately. Compared to the expensive medical bills for surgery, the cost to...

What are Shoulder Rotator cuff muscles? Why they might be the source of your upper back, neck and shoulder pain?

WWW.PTcares.com One of my clients was diagnosed with Rotator cuff muscles injury.  She asked me about the rotator cuff muscles and why they are contributing to the shoulder pain and neck pain.  Today we will talk about the function of rotator cuff muscles. There are 4 rotator cuff  muscles: Supraspinatus Infraspinatus Teres Minor Subscapularis The primary function of the rotator cuff muscles is to maintain the stability of the glenohumeral (GH) joint, which is part of the shoulder complex.  As you can see, there are 3 bones in the shoulder complex: Scapula, clavicle and humeral bone. When the rotator cuff muscles are weak and could not maintain the humeral head close to the glenoid of the scapula, the humeral head might not glide smoothly and impinge surrounding tissues, causing connective tissue problems, such as tendinitis, bursitis, capsulitis, or rupture of tendons or ligaments. When the connective tissues and mus...
