“…However, all of the patients who underwent MRI had evidence of intraosseous fluid collections at the tibial BioScrew site (Linvatec, Largo, FL), and four of six had fluid collections at the femoral screw site [11]. Lajtai reported similar findings at five years using patella tendon graft and a bioabsorbable screw (copolymer 85/15 D,L-lactide/glycolide) [13].…”

“…The bioabsorbable materials commonly used for interference screws include polyglycolic acid (PGA), polylactic acid (PLA), polyparadioxanone (PDS), polymer of PGA/ PLA, and various stereoisomers of the lactic acid (PDLA) molecule [9]. The screw used in this study was made of copolymers composed of L-lactic acid, D-lactic acid and trimethylene carbonate (TMC) (Inion Hexalon TM , Inion Oy, Tampere, Finland).…”

There has never been an MRI study of tunnel widening comparing bioabsorbable to metal screw fixation in autologous hamstring anterior cruciate ligament (ACL) reconstruction. We randomized 62 patients to hamstring ACL reconstruction with either a bioabsorbable (n=31) or metal screw (n=31) fixation. The evaluation methods were clinical examination, KT-1000 arthrometric measurement, the International Knee Documentation Committee and Lysholm scores, and MRI. There were no differences between the groups preoperatively. Fifty-five patients (89%) were available at a minimum of 2-year follow-up (range 24-36 months). There was tunnel widening in both groups, but the increase was significantly greater in the AP dimension of the femoral tunnel in the bioabsorbable screw group compared to metal group (P=0.01). The tibial tunnels showed no intergroup difference. Ninety-four percent of the knees were normal or nearly normal according to the IKDC scores and the average Lysholm score was 91 with no intergroup difference. The follow-up AP tibial tunnel diameter was smaller with normal knee laxity compared to abnormal knee laxity. The graft failure rate in the bioabsorbable screw group was 23% (7/31 patients) and 6% (2/31 patients) in the metal screw group. The use of bioabsorbable screws resulted in more femoral tunnel widening, and more graft failures compared to metal screws. The tunnel widening in the tibia was associated with the knee laxity (P=0.02).

“…They typically are made from poly-L-lactic acid and offer similar or superior fixation [11,21] in comparison to that of similarly designed metal screws for ACL reconstruction [16,17]. Comparative studies between biodegradable and metallic screws have shown no superiority of one over the other in terms of pain, Lachman and pivot shift tests, Tegner activity level, and Lysholm score [12,13,15,17]. Biodegradable screws have several advantages over metallic screws: they do not have to be removed, they may avoid the damage metallic screws can cause to the patellar bone/ tendon graft in the tunnel, and they avoid metal artifacts with imaging.…”

Background Biodegradable interference screws in anterior cruciate ligament (ACL) reconstruction have gained popularity because of their similar or superior fixation strength in comparison to metallic interference screws and because they do not cause imaging artifacts and do not need to be removed. Case Description We report the case of a 23-year-old man who presented with slowly progressive firm swelling of 2 months' duration at the site of the tibial tunnel 3 years after ACL reconstruction using a biodegradable interference screw. After curettage and débridement, the material was sent for histopathologic examination, which was reported as a fibroxanthoma. Literature Review Reported complications are osteolysis around the screw, allergic reaction, sterile abscess formation, ganglion cyst formation, and intraarticular migration.
