Knee Pain Diagnosis
The most common type of injuries we see at JOI are as follows:
Degenerative knee arthritis. Basically this is the degree that your cartilage is wearing off the end of each bone at the knee. This erosion can lead to a change of alignment at the knee. This is referred to either knocked knees or bowlegged in layman’s terms.
Causes and Risk Factors Related to Knee Pain
The causes of knee pain are very diverse and varying.
Aging: As we age the cartilage that surrounds and cushions the knee begins to wear away in the joint. As our cushioning layer of cartilage becomes less and less than your pain will increase. This condition can worsen until it’s bone on bone.
Trauma: Force to the knee that over powers the structure and leads to injury. An example is an ACL tear. During activity if the knee joint is extended forcefully like being tackled in football and the joint is also twisted than the ACL can rupture.
Weakness. If your muscles that support the knee are not strong than your knee will lack control and stability. This can lead to pain.
Knee Pain Biomechanics
A classic example is that females usually have wider hips. Since female’s hips are wider it can cause the angle of the knee cap to not follow is normal path with movement of the knee.
Overuse: If the knee joint is continually pushed past its limit of tolerance than a physical breakdown will result leading to pain.
Obesity: The more load that the knee is forced to carry the more the negative stress on the joint.
High Impact Activity: As with obesity the more stress of high load activity you put on your joint the more chance of injury.
Knee Pain Test
JOI Describes the Various Knee Pain Tests and Diagnostic Tools X-ray:
Classic tool that can help show the level of loss of cartilage in the joint. X-ray can help to show if there is alignment issues with the knee cap. An x-ray is to diagnose fractures and the extent of arthritis or the loss of joint space in the bones or joint.
Produces an image of all the soft tissue structures of the knee joint to allow diagnosis of an tear. Considered the new standard for diagnosis. Each MRI has a different signal strength and clarity. Patients who are claustrophobic may choose an open MRI.
Manual Special Tests of the Knee
Both your orthopedic MD and Physical Therapist at JOI can perform specific joint movements that can help to identify pathology. One such example is a Lachman’s test. This test is used to detect an ACL tear. To perform this test, the knee is slightly flexed lying down. Next the upper leg is stabilized and force is applied to the lower leg in a specific upward angle. If the lower leg shifts up than there may be a tear. Every ligament of the knee has a specific test to check its viability. Here are some of the other tests:
McMurray, Anterior Drawer, Posterior Drawer, Pivot Shift, Appley’s Compression and Distraction Test, Varus, Valgus, and Clark’s Tests.
JOI Knee Pain Treatment Plans
Your physician will do an examination of your knee with x-rays. Depending on the type and severity of the arthritis, your MD with provide a treatment plan for you. They may prescribe anti-inflammatory or other medications. Possibly a knee brace to include Unloader(OA) brace to support the knee. Also, physical therapy for an improvement in mobility and strength. Laser, modalities and other treatments for pain control. Activity modification to include swimming and stationary cycling is also a good idea. In addition, injections to the knee may be considered. If you to have pain without benefit from conservative care, a total joint replacement may be considered.
In this paragraph, we will explain an ACL Reconstruction treatment plan. Physical Therapy prior to surgery for ROM, strength and the reduction of swelling. Surgery is the option to repair the torn ligament with either an autograft (own tissue) of allograft (cadaver). Initial PT starts 2 days after surgery. Post OP bracing right after surgery with progression to a functional brace as the rehab progresses. After about 5 months’ return to jogging and sports activity around 9-12 months.
Conservative treatment with Physical Therapy to advance strength and functional activity. Initial stages with modalities to control pain/inflammation to include laser. Surgical intervention if conservative treatment fails. The recovery time is usually about 6-10 weeks if with only arthroscopic debridement.
Patella Femoral Inflammation:
This condition treatment usually starts with an anti-inflammatory medication and physical therapy. Therapy consists of modalities to include laser for pain/inflammation control. It is important for the initial avoidance of squatting, steps and kneeling activity that place negative pressure on knee cap. Bracing can help control the motion and position of the knee cap. Taping can also be helpful to improve the tracking of the patella. Specific strengthening exercises for the quadriceps muscles with emphasis on the VMO. Also, stretching to focus on the ITB band and hamstring muscles. In the final stages of rehab, there is a focus on eccentric strength and movement and return to sport activities.
If you have knee pain after a mechanism of trauma, you should be properly evaluated by an MD. Further damage can occur if your treatment is improper. Therefore, if your knee motion is not correct, this could then eventually impact your hip or back.
JOI Offers Conservative Physical Therapy Approaches for Treating Knee Pain
It is not uncommon for people of various age groups to have knee pain. There are several different ways to treat pain in the knee in physical therapy. Strengthening is very important in order to obtain a full recovery. Range-of-motion is also a typically way to treat those who are having painful knee symptoms. Lastly and perhaps most importantly is keeping up with your health. Weight loss and a healthy BMI are always recommendations in the treatment of knee pain.
