“…Bioabsorbable screws are manufactured from lactic acid polymers or lactic acid/glycolic acid copolymers. 28 Various types of materials are available in the market for designing bioabsorbable screws and include polyglycolic acid, polylactic acid, polyparadioxanone, poly-L-lactide, and several other stereoisomers of lactic acid. The clinical difference in these implants is the absorption rate and local tissue reaction.…”

“…[25][26][27][28][30][31][32][33] Disadvantages and possible complications include screw breakage, inflammatory and foreign body reactions, cyst formation, and local bone lysis. [25][26][27][28][30][31][32][33] Four basic tenets as described by Speer and Warren 34 apply to bioabsorbable implants. The implant needs adequate fixation strength, the material must have the ability to maintain stability while tissue healing is occurring, the material should not resorb so slowly that breakage and migration are possible, and the materials must not cause reactions of any kind.…”

Subtalar joint arthroereisis is a surgical modality that has been shown to be an effective procedure for flexible flatfoot in both pediatric and adult populations. Despite advances in understanding its mechanics and function, complication and implant removal rates remain as high as 30% to 40%. Analysis was performed to determine the survivability of 2 subtalar joint arthroereisis implants, absorbable and nonabsorbable, used alone and in combination with other procedures in both the adult and pediatric populations. The 95 total arthroereisis procedures were analyzed in several major categories: absorbable implants versus nonabsorbable implants and adult versus pediatric patients. Each major group was then further subdivided to create further subgroups: absorbable isolated procedures, absorbable combined procedures, nonabsorbable isolated procedures, and nonabsorbable combined procedures. The overall survival rates were 83% for absorbable implants and 81% for nonabsorbable implants. A total of 11 (17%) absorbable implants and 6 (19%) nonabsorbable implants were removed, respectively, at an average of 9 months and 23 months postoperatively. When used alone and in combination with other procedures, 36% and 13% of absorbable implants and 18% and 19% of nonabsorbable implants, respectively, were removed. When comparing adult versus pediatric populations, the overall survival rates of the absorbable and nonabsorbable implants were 81% for absorbable implants and 79% for nonabsorbable implants in the adult population and 85% for absorbable implants and 100% for nonabsorbable implants in the pediatric population.

“…Several bioabsorbable screw materials exist, including polyglyconate (PGA) [1], poly-D-L-lactide (PDLLA), polylactic-co-glycolic-acid (PLGA), and composites of PLLA. These bioabsorbable materials pass through five stages of degradation: hydration, depolymerization, loss of mass integrity, absorption, and elimination [12].…”

Background Arthroscopically assisted anterior cruciate ligament reconstruction using a bioabsorbable tibial fixation screw is occasionally complicated by pretibial cyst formation. The few case reports describing pretibial cyst formation noted several graft types and fixation techniques, making it difficult to establish one etiology. Some literature suggests cysts form from communication between the joint and pretibial area leading to extravasation of joint fluid, maturing into a cyst. We propose the development of cysts after PLLA screw use may be related to a foreign body reaction. Questions/purposes We propose this foreign body reaction (1) relates to the biochemical breakdown of bioabsorbable materials; and (2) differs from cystic formations resulting from joint communication. Methods We retrospectively reviewed seven patients who developed pretibial cysts at least 2 years after original primary ACL reconstruction surgery. MRI was used to visualize the extent of cystic formation. Cysts were treated by débridement with specimens sent for histologic analysis. Cyst appearance had a 3-year incidence of 5%.
