Patellofemoral Dysfunction

The patellofemoral compartment is commonly known as the knee cap joint.  The knee cap (patella)  sits on tops of the thigh bone (femur). 


With activity there is movement or tracking of the knee cap along the femoral groove.  If there is misalignment of the knee cap within the femoral groove, the patient experiences pain.

Lateral release is a common surgical treatment for patellofemoral dysfunction  which involves cutting the lateral retinaculum,  the fibrous tissue that supports the kneecap.  


The goal is to release abnormal lateral tension on the knee cap thereby allowing  normal tracking to occur.  Rehabilitation following surgery is extensive  usually requiring 3-5 months of physical therapy.  Unfortunately the body only requires  adjustments in very small increments such as millimeters.  Regrettably surgeons typically make adjustments in centimeters.  The difference is a 10 fold and the result can be an over adjustment with resultant  pain and deterioration of the cartilage.

Once there is loss of cartilage in the patellofemoral joint another surgery is recommended aimed at repairing the cartilage. 

Fortunately regeneration of cartilage in the knee is now available without surgery.  Regenexx enables patients the opportunity to regenerate cartilage by using their own stem cells.  Centeno et. al., have demonstrated cartilage regeneration using stem cell therapy.  Regenexx is a simple needle-in, needle out procedure that avoids surgery and anesthesia.

Patella Tendon Repair and Rehabilitation

The patella tendon connects the knee cap ( patella) to the shin bone (tibia). It serves to stabilize the knee and allows the quadriceps muscle group to straighten the leg.


The patella tendon is prone to rupturing in individuals with a history of patella tendon injury such as jumper’s knee or osteoarthritis. Injuries of this type  weaken the patella tendon and in the event of strong contraction of the quadriceps  such as landing from jump, the patella tendon may tear or rupture.

Corticosteroid injections given to address the inflammation seen in patella tendon injuries are also known to predispose the individual to ruptures.  At the Centeno-Schultz Clinic patella tendon inflammation and pain has been successfully  treated with prolotherapy .  This therapy does not predispose patients to patella tendon rupture.

Patella tendon repair most commonly involves surgery.  Following surgery rehabilitation for patella tendon repair normally involves little or no weight-bearing on the affected knee and wearing a knee brace or cast prevent the knee from bending. This may be required for more than 6 weeks.

Rehabilitation from a patella tendon repair is extremely slow and it may take between 6 and 12 months before the patient is able to return to sports.

Patient now have the option to utilize their own stem cells to regenerate the tendon and forgo surgery through RegenexxRepair of torn tendons has already been achieved through this unique technique.  See our patient testimonials on the success of using stem therapy for the repair of tendons.
