“…In fact, the insertion of the IS requires the creation of quite a large bone defect and causes hoop stresses within the cortical wall. The use of a biodegradable screw may also lead to problems such as cyst formation, as described in the literature for other anatomical sites (Sprowson et al, 2012). Additionally, obtaining the desired biceps length with the IS technique can prove challenging (Denard et al, 2012).…”

“…properties. In 2012, Sprowson et al (13) completed a ten-year MR imaging observational study of patients with bioabsorbable polylactide interference screws used for tibial fixation and found that no resorption had occurred after four years in any of the patients. During the ten-year follow-up period, however, half of their patients displayed small cystic collections within the tibial tunnel.…”

We report the case of a patient with a painful subcutaneous nodule, measuring 13 mm × 17 mm, at the pretibial graft aperture site, which presented two years after a successful anterior cruciate ligament reconstruction with an autologous hamstring graft. A bioabsorbable poly-L-lactide interference screw was used for graft fixation at the tibial aperture. The patient underwent surgical excision of the lesion and curettage at the tunnel aperture. Grossly, extruded fragments of the screw and a thick pseudocapsule of surrounding tissue were excised. There was no communication between the tunnel aperture and the knee joint. The graft was also intact. Histological analysis revealed fragments of the bioabsorbable material in association with fibrous and granulomatous chronic inflammatory cells. This was consistent with a foreign body reaction. The patient subsequently recovered and resumed preinjury level of activity. To the best of our knowledge, this is the first report describing a nodular granulomatous type reaction to foreign bioabsorbable poly-L-lactide screw material subsequent to an anterior cruciate reconstruction surgery.

“…This cystic process may result from degeneration and/or partial tearing of the graft, or it may be related to a reaction to the fixation material, nonabsorbable sutures, and allografts. 87,88 Cyst formation can be a cause of graft tear in the absence of injury (►Fig. 21).…”

The growing number of patients undergoing arthroscopy or surgery of the knee for ligamentous injuries has led to a greater need for postoperative imaging because of poor outcome, recurrent symptoms, or a new injury. MRI is the most important imaging method when evaluating the postoperative knee. Radiologists should be familiar with the particular reconstruction technique applied to each examinee, know the spectrum of normal postoperative findings, recognize those findings that may be related to symptoms of failed reconstruction, as well as those lesions that are irrelevant to the previous surgery yet responsible for the new clinical symptoms. In view of the continually evolving surgical techniques, this review presents the current concepts of MRI evaluation of the postoperative knee ligaments based on recent literature reports.
