We will compare two groups for acute patella tendon repair: one treated with surgical
anchors and the second, with transpatellar tunnels.
The patella tendon is located in the knee, and is attached to the leg bone and the patella
bone (knee cap). The quadriceps muscle (an important tight muscle) attaches to the patella
bone and allows for extension and flexion of the leg. Rupture of the patella tendon occurs
mainly in people under the age of 40 years old with an active lifestyle. Normally, surgical
repair is needed to fix this injury. The widely accepted surgery for this injury consists
in drilling 2 holes in the patella bone that are used to anchor the patella tendon in place.
This surgery has some complications such as re-rupture of the tendon, breakage of the bone,
etc. Some investigators have tried different techniques to avoid these complications with
variable results. We want to use 2 anchors in the bone to avoid making holes in the patella
bone, decreasing complications and surgical time, and hopefully, allowing for a better
surgical repair. We will have 2 arms. One group will have the standard of care technique
and the second group will have the anchors technique. We will follow up with our patients
after the surgery to record their progress, and complications, if any. We will also have a
standardized physical therapy program for consistency and to avoid any problems.
1. Stage of Disease: Acute ruptures of the patella tendon, no more than 3 weeks since
the time of injury.
2. Age: 18 years old and up.
3. Performance status: Patients with no other previous illnesses that prevented them to
ambulate normally (without help of devices).
4. Informed consent requirements: One person from our research staff will approach the
patient after the diagnosis has been made. The diagnosis will be made by the doctor
in charge on the patient care based on the medical history, physical exam and image
studies (MRI). We will explain the benefits/risks to be part of the study and that
they are not obligated to be part of it as part of their care.
1. Prior treatment: Patients with chronic patella tendon ruptures (more than 3 weeks).
2. Prior other diseases: diseases with systemic collagen deficiencies.
3. Infection: Patients with active infection will be disqualified.
