Which screws are best for ACL reconstruction?
BACKGROUND: Graft fixation during anterior cruciate ligament (ACL) reconstruction can be achieved with use of either bioabsorbable screws or metal screws. Although bioabsorbable screws and metal screws have similar fixation strengths, bioabsorbable screws eliminate the need for removal.
How long do biodegradable screws last?
However, the evidence on the use of biodegradable interference screws in anterior cruciate ligament (ACL) reconstruction is still scarce. Although the screws promise to degrade within approximately 12-24 months after surgery, several cases have been reported in which this did not happen [1, 10, 15].
How many screws are used in ACL surgery?
In addition, in the double-bundle technique, we used four interference screws for the fixation, while in the single-bundle technique only two interference screws were used. All these factors could explain the superiority of the double-bundle ACL comparing to the single-bundle ACL even at the 10-year follow-up.
What is EndoButton made of?
The first is the EndoButton which is made of Titanium 6AL 4V ELI alloy (ASTM F136). Its length is from 12 to 18 mm and its width is from 4 to 6 mm. It is oblong in shape with four holes through which suture is threaded.
Are there screws in ACL reconstruction?
In ACL reconstruction, a replacement ligament (graft) is attached to tunnels drilled into the end of the femur (thigh bone) and tibia (shin bone). Often screws are used to attach the graft to the bone. Traditionally, metal screws have been used.
Which implant is best for ACL surgery?
Table 1
| Variable | SW | P |
|---|---|---|
| Failure load (N) | 110.1 ± 9.3 | 0.39 |
| Failure elongation (mm) | 23.2 ± 2.6 | 0.36 |
| Yield load (N) | 82.8 ± 7.2 | 0.40 |
| Yield elongation (mm) | 15.7 ± 2.1 | 0.37 |
Do screws stay in knee after ACL surgery?
Your surgeon will make a tunnel in your bone to pass the new tissue through. The graft tissue will be positioned in the same place as the old ACL and held in place with screws or staples that will remain in your knee permanently.
What are ACL reconstruction screws made of?
Bioabsorbable screws are made from poly L-lactic acid (PLLA) and are absorbed by the body.
The EndoButton is a commonly used device for femoral fixation of anterior cruciate ligament grafts. Intraoperatively, it was noted that the femoral tunnel exit was within the suprapatellar pouch, with the displaced EndoButton lodged between the posterior aspect of the lateral tibial plateau and the capsule.
What is Endobutton technique?
The authors describe a technique with a single anterior incision and fixation with an internal button, the Endobutton. The Endobutton delivers and locks the tendon into a hole in the radial tuberosity. The Endobutton technique was used in 12 patients who were allowed early active mobilization.
Which screw is used in ACL surgery?
Bioabsorbable interference screws are used extensively in orthopaedic procedures, and they are frequently used for graft fixation in ACL (anterior cruciate ligament) reconstruction.
What are the screws in ACL surgery made of?
Bioabsorbable screws are made from poly L-lactic acid (PLLA) and are absorbed by the body. This prospective, randomized study compared the safety and efficacy of the PLLA screw with that of the metal cannulated interference screw for anterior cruciate ligament reconstruction.
