I was biking and hiking in India over the summer when I injured my knee badly. I was lucky enough to find my way to a large surgical center there where one surgeon was an ‘expert’ on knee injuries using a new grafting technique. Part of my quadriceps muscle was used to replace the torn ligaments. Now that I’m back in the U.S. and in rehab, I’m looking for any information that might help my physical therapist know what was done in the surgery so she can create a program to match. Can you help me? I don’t remember the name of the clinic I went to but I know I was in Ahmedabad (western India, south west of New Delhi). Can your orthopedic surgeon contact someone and find out what was done?

We do not provide that type of on-line service but we can tell you there was a recent article published in a well-known orthopedic journal from that area. Specifically, one surgeon from the Saumya Orthocare: Centre for Advanced Surgeries of the Knee Joint in Ahmedabad, India conducted a study of 32 patients with chronic patellar insufficiency (i.e., the knee cap kept dislocating).

In this study, the superficial quad technique was used as the graft to replace the ruptured medial patellofemoral ligament (MPFL). The quadriceps muscle is the large four-part muscle along the front of the thigh. The quadriceps tendon attaches to and around the patella.

The MPFL is the stabilizing ligament that helps keep the patella (knee cap) tracking up and down over the knee. When the patella is dislocated, this ligament is almost always ruptured. And once a ligament is torn, it does not repair or heal itself. Chronic, recurrent patellar dislocation with MPFL rupture is referred to as medial patellofemoral insufficiency.

In order to regain patellar stability and prevent repeated dislocations (ligament insufficiency leading to patellar instability), (surgical) reconstruction is needed. There are many different ways to reconstruct the damaged ligament. Most techniques involve a tendon graft to replace the ligament. Attaching the graft in place (called fixation) creates problems of its own. That’s one reason why surgeons are looking for better ways to accomplish the reconstruction procedure.

If, in fact, you had a superficial quad technique to repair a torn medial patellofemoral ligament, you will likely experience good results. According to the Indian surgeon who is developing and investigating this surgical approach to patellar insufficiency, there are five advantages or “plusses” to this new technique.

First, the graft is a better anatomic match to the original medial patellofemoral ligament (MPFL) in terms of width, breadth, and length. The natural or native MPFL is thin, broad, and sheet-like; so is the quadriceps slip used in this procedure. Two, the superficial quadriceps tendon graft is not as stiff as the commonly used hamstring tendon graft. A strong, stiff graft puts more load on the patellofemoral joint and can cause patellar fracture later.

Three, the superficial quadriceps graft does not have to be held in place with screws or wires. This makes it possible to attach the graft to the medial border of the patella where the MPFL is located normally. The result is a more accurate re-creation of patella biomechanics and elimination of complications from patellar fixation. This is helpful because most common problems that develop after MPFL reconstruction can be traced back to either the type of graft material or the way in which the graft is held (i.e., fixation technique used) in place.

Four, the graft can be harvested arthroscopically with a very small incision. And five, at least in the short-run (first three years), the results are equal to outcomes when compared with using the hamstring tendon.

In the published article, the surgeon described and displayed photographs of the 10-steps of this surgical technique. Your therapist may want to take a closer look at this information.

The author begins with arthroscopic examination to assess all injuries and damage inside and around the knee joint. Graft harvest, preparation of the graft, and attachment of the graft are part of steps two through eight. The final steps involve getting the most optimal graft length and then repairing any other soft tissue injuries (e.g., medial retinaculum).

In the follow-up of these 32 patients, no one had recurrent patellar dislocations or other patellar complications. One-fourth of the group had problems bending the knee fully and went to physical therapy to resolve the issue. The author suggested that future improvements of the superficial quadriceps procedure (e.g., better fixation points at the femur, elimination of scarring, better arthroscopic techniques) may help prevent this complication and further improve results.

In addition to reviewing this article, you may want to see an orthopedic surgeon locally for follow-up. He or she can initiate contact with the surgical center in India where you were treated to obtain more information.
