| Abstract |
| Abstract The Statak is a suture anchor device
used for attaching soft tissue to bone. This is a report on six knees
in which this device was used to repair partial avulsion of the patellar
ligament during total knee arthroplasty (TKA). The six patients were
all women. The average age of the patients was 69 years. The diagnosis
was osteoarthritis in three patients, rheumatoid arthritis in two,
and steroid arthropathy in one. Three of the operations were revision
arthroplasties. In all six cases, approximately half of the patellar
ligaments were accidentally detached from the tibial tubercles during
surgery, and were repaired using the Statak devices. The average
length of follow-up was 3 years. The Knee Society knee score improved
from an average of 15 points preoperatively to 87 points at the latest
follow-up. The average total range of motion measured 104° before
surgery and 108° at the latest follow-up. Three of the six knees
operated on had no extensor lag. The suture anchor simplifies the
secure fixation of the ligament to bone. The procedure can be performed
easily and quickly. In our opinion, the Statak device has proven
itself to be effective for the repair of partial patellar ligament
avulsion during TKA. |
