“…Measurements should be performed in 3D CT, if available, as TW does not seem to be an organized symmetric expansion of the tunnel (22). The tibial tunnel diameter was measured at the midpoint of the tibial tunnel, perpendicular to the tunnel axis (23). We found ICC scores between 0.84 and 0.99, which indicates this measurement conditions provide optimal accuracy for measuring tibial tunnel diameter.…”

Purpose. To evaluate the effect of β-tricalcium phosphate (BCP) concentration in bioabsorbable interference screws on tibial tunnel widening after hamstring anterior cruciate ligament reconstruction. Methods. A total of 37 patients with a mean follow-up of 4.6 years were included for analysis. Bioabsorbable interference screws containing 60% BCP and 40% poly-L,Dlactic acid (PLDLA) (60BCP group) or bioabsorbable interference screws containing 30% BCP and 70% PLDLA (30BCP group) were used for tibial graft fixation. A 16-slice multislice computertomography scanner with post-process multislab reconstructions was used for tibial tunnel evaluation. The tibial tunnel diameter was measured at the midpoint of the tunnel. Tunnel widening was defined as an increase of more than 2 mm compared to the intraoperative drill diameter. Results. Patient demographics were not statistically different between both groups. The number of patients that showed tibial tunnel widening was high but did not differ statistically significant between the 60BCP and 30BCP group: 76% (n = 17) versus 75% (n = 20) for 60BCP and 30BCP group, respectively. The average increase in tibial tunnel diameter did not differ statistically significant between the groups; the tibial tunnel diameter increased with an average of 3.36 mm (SD 1.86) and 2.94 mm (SD 1.63) for the 60BCP and 30BCP group, respectively. Conclusions. A high incidence of tibial tunnel widening was observed when bioabsorbable interference screws containing different concentrations of β-tricalcium phosphate were used to fixate the hamstring graft in anterior cruciate ligament reconstruction. Increasing the concentration β-tricalcium phosphate did not result in less tunnel widening.

“…In this study, in order to obtain more convincing results, we matched the factors that may play a role in graft maturity and bone tunnel enlargement in both groups, including age, follow-up time, type of graft and fixation, and bone tunnel placement technique. 6,30,32,36,38 Acute infectious arthritis can cause a great deal of damage to the joint within a short span of time. Researchers have found that bacteria can directly invade joint tissue, causing cell death and extracellular matrix degradation.…”

Background: Joint infection after anterior cruciate ligament (ACL) reconstruction is a rare but serious complication. Purpose: To assess the effect of joint infection on the graft, cartilage, and bone tunnel using magnetic resonance imaging (MRI) after arthroscopic single-bundle ACL reconstruction with autologous hamstring tendons. Study Design: Cohort study; Level of evidence, 3. Methods: This retrospective matched cohort study included 26 patients who underwent arthroscopic single-bundle ACL reconstruction with hamstring tendon graft at the authors’ institute between January 2002 and December 2017 and developed postoperative joint infection. These patients were matched 1:3 to patients who did not sustain joint infection after ACL reconstruction (control group). MRI scans were collected at the time of follow-up. The following parameters were evaluated: graft signal-to-noise quotient (SNQ); graft signal intensity at the bone-graft interface and within the knee joint; bone tunnel enlargement at the tunnel aperture, midsection, and exit of the tibial and femoral tunnels; and cartilage integrity. Results: The average follow-up time was 47.8 months in the infection group and 48.5 months in the control group. Compared with the control group, the infection group had a significantly higher SNQ (20.01 ± 12.08 vs 7.61 ± 6.70; P = .014) as well as a higher signal intensity at the bone-graft interface ( P = .037) and higher Howell grade ( P = .031). The mean enlargement at the femoral tunnel aperture was 31.20% ± 26.76% in the infection group and 19.22% ± 20.10% in the control group ( P = .037). The articular cartilage of the patellofemoral and lateral femorotibial joints showed more degenerative change in the infection group. Conclusion: Study findings indicated that graft ligamentization and incorporation graft maturity were inferior in patients who experienced a joint infection after ACL reconstruction compared with patients who did not.
