Osteoarthritis of the knee

Degenerative Osteoarthritis of the Knee

Avoiding and preventing the surgery should be a primary goal of the physician treating orthopedic disease of the knee joint.

The knee is primarily a hinge joint and its primary function is to flex and extended with it's articulation with the tibia and the femur. The knee joint is affected by all three body planes.

Transverse Plane
Excessive internal rotation of the lower leg produced by excessive foot pronation is a primary cause for knee instability. When the foot overly collapses or pronates, the leg goes through excessive internal rotation during the mid stance phase of the gait cycle. This offsets the normal axis of motion of the knee joint causing the normal range of motion of the knee to be affected.

Frontal Plane
Knock knee position (coxa vara genu valgum) crests additional knee instability.

Lateral Plane
Hyper-extension of the knee along with tight posterior compartment shortages (equinus of gastrocnemius (calf) and hamstrings) are another deforming force on knee mechanics.

New methods of biomechanical and ergonomic intervention

• 3-D weight bearing kinematic imaging is a static and dynamic cyclic load stress analysis for providing the physician with critical information relative to loadbearing mechanics of the limb, pelvis and spine. Understanding the mechanical causes of knee disease is critical in both preventing surgery reducing medical costs and treatment and providing effective postoperative treatment regimens, especially in the case of knee implant surgery.
• Critical surgical planning and biomechanical evaluation of of all three body planes (limb length, leg positioning (frontal plane) and rotation, muscle compartment strengths and weaknesses) are necessary evaluations prior to surgical intervention.
• If the implant surgery must be done, the patient should be evaluated postoperatively at three and six months as the implants seats in both the tibia and the femur postoperatively abd then followed every two years for adaption changes as the implant and other structures heal and compensate for surgical intervention. 

Using 3-D weight-bearing kinematic imaging provides a true biomechanical and ergonomic snapshot of the patients static and functional conditions relative to cyclic load. Utilizing 3DO imaging (Three Dimensional Orthodynamics) is a very affective diagnostic tool for the assessment of both pre-surgical and post-surgical changes of the knee joint.

Chondromalascia of the Patella (Knee)

Chondromalascia of the patella (knee cap) is a biomechanical problem resulting from abnormal tracking of the patella in the Femoral Groove of the femur.

• The cause is due to excessive transverse plane rotation of the leg as a result of foot pronation.
• Most of the treatments provided are symptomatic with injections, surgery, and rehabilitation. Unfortunately few physicians look at the biomechanical cause of the condition.
• The knee primarily works as a hinge anatomically and as a result is designed to work on one plane of motion which is flexion and extension.
• When the foot overly pronate's or collapses, it causes the internal rotation of the lower leg to increase thereby setting off the normal axis of motion of the knee joint causing the patella to abnormally track in the femoral groove.

Understanding the complex biomechanics of the foot and its affect on transfers plane limb rotation is critical in the proper treatment of this condition.

New medical treatments and have been developed to better understand the internal mechanical function of the foot and static and dynamic environments and it's effect on abnormal transverse plane limb rotation.

3-D weight-bearing kinematic imaging is the most sophisticated method for analyzing this condition. This is done through the utilization of a computer weight-bearing 3-D mechanical tracking system referred to as 3DO (Three Dimensional Orthodynamics).   This analytical computer system was developed by Digital Orthotics after many years of research and development.

Low Back Pain

Low back pain is one of the most common conditions seen in Orthopedics. The treatment varies substantially depending on who you see.

• Most back pain is due to a cumulative trauma from loadbearing forces affecting the body as we walk and stand and work and play.
• The Spine is affected by all three body planes and for successful treatment, all body planes need to be evaluated and treated,
• Understanding the loadbearing conditions that caused spinal pain is vital in the successful treatment of the condition.

Advancements in medical imaging has substantially improved our understanding of the complex factors that create not only spinal pain but pelvic hip knee and limb pain.

3DO imaging, (3D weight-bearing kinematic imaging), represents the latest advancements in medical imaging to understand simple to complex cyclic load conditions of the body interacting with the ground.

Bioengineered Devices represent a new and more advanced and precise method to controlling the body's interaction with reactive ground forces.
