We will compare two groups for acute patella tendon repair: one treated with surgical anchors and the second, with transpatellar tunnels.
Condition | Intervention | Phase |
---|---|---|
Acute Patella Tendon Rupture |
Procedure: Repair with transpatellar tunnels Procedure: Repair with suture anchors. |
Phase IV |
Study Type: | Interventional |
Study Design: | Treatment, Randomized, Open Label, Parallel Assignment |
Official Title: | Surgical Treatment for Acute Patella Tendon Rupture: a Prospective, Randomized Study Comparing Transpatellar Suture Tunnels Method vs. Suture Anchors. |
Estimated Enrollment: | 24 |
Study Start Date: | September 2008 |
Estimated Study Completion Date: | January 2012 |
Estimated Primary Completion Date: | September 2011 (Final data collection date for primary outcome measure) |

A: Active Comparator
Repair with suture anchors: The insertion points for the three suture anchors will be marked with electrocautery. The anchors will be placed approximately 2 mm from the articulate surface; placing them too superficially may increased the joint reactive force and lead to abnormal patella femora joint mechanics. Pilot holes will be drilled with a 3.2-mm drill bit parallel to the patella, avoiding penetration of the articular surface. Three Suture anchors (Arthrex, Naples FL) will be threaded with two No. 5 Fiberwire (Arthrex, Naples FL) sutures and will be inserted and deployed in the pilot holes in the usual manner.

B: Active Comparator
Repair with transpatellar tunnels: We will make a small horizontal trough at the inferior pole of the patella. Multiple, braided Krackow sutures will then be placed through the substance of the tendon using no. 5 Fiberwire (Arthrex, Naples FL) suture. Three to four drill holes will then be made through the patella. Using a suture passer, the sutures will then be brought from distal to proximal and tied over the superior pole. The knee will be flexed to 45 degrees. The tendon will be repaired adjacent to the articular surface and not to the anterior surface of the patella.

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.
