Study Design: Retrospective Cohort Study. Objective: To determine whether 3D-printed porous titanium (3DPT) interbody cages offer any clinical or radiographic advantage over standard solid titanium (ST) interbody cages in transforaminal lumbar interbody fusions (TLIF). Methods: A consecutive series of adult patients undergoing one- or two-level TLIF with either 3DPT or ST "banana" cages were analyzed for patient reported outcome measures (PROMs), radiographic complications, and clinical complications. Exclusion criteria included clinical or radiographic follow-up less than 1 year. Results: The final cohort included 90 ST interbody levels from 74 patients, and 73 3DPT interbody levels from 50 patients for a total of 124 patients. Baseline demographic variables and comorbidity rates were similar between groups (P >.05). Subsidence of any grade occurred more frequently in the ST group compared with the 3DPT group (24.4% vs 5.5%, respectively, P =.001). Further, the ST group was more likely to have higher grades of subsidence than the 3DPT group (P =.009). All PROMs improved similarly after surgery and revision rates did not differ between groups (both P >.05). On multivariate analysis, significant positive correlators with increasing subsidence grade included greater age (P =.015), greater body mass index (P =.043), osteoporosis/osteopenia (P <.027), and ST cage type (P =.019). Conclusions: When considering interbody material for TLIF, both ST and 3DPT cages performed well; however, 3DPT cages were associated with lower rates of subsidence. The clinical relevance of these findings deserves further randomized, prospective investigation. [ABSTRACT FROM AUTHOR]

Background: There are several approaches such as the Bankart repair, Latarjet, and Remplissage to treat recurrent glenohumeral instability. Indications: We chose to augment an arthroscopic Bankart repair with a Remplissage in this 26-year-old patient given the presence of a Hill-Sachs lesion, history of recurrent shoulder dislocations, and young age of the patient. Technique Description: We established four portals using previously well-documented techniques. The Hill-Sachs lesion was evaluated using the anterosuperior portal. Two anchors were placed, one on both the superior and inferior aspects of the Hill-Sachs lesion. The sutures were shuttled through the knotless anchor mechanism and tensioned after confirming the cannula was through the deltoid. Then, we completed the Remplissage by repairing the infraspinatus tendon and capsule into the posterior humeral head. Results: The Remplissage procedure is very successful at reducing recurrent instability in young, active patients. Previous studies have reported very low rates, even 0% recurrent instability, after surgery with 80% to 90% of patients returning to sports. Studies have also documented excellent patient-reported outcomes at short- to mid-term follow-up. Complication rates are historically lower when the Remplissage is done with an arthroscopic Bankart repair than the Bankart repair alone. Discussion/Conclusion: The Remplissage procedure is a safe, effective option at reducing future instances of shoulder dislocations in conjunction with Bankart repairs. Patients can expect to return to their active lifestyles, with many patients achieving the same level of activity as before the initial shoulder dislocation.

We sought to determine the impact of bacterial inoculation and length of exposure on the mechanical integrity of soft tissue tendon grafts. Cultures of Staphylococcus epidermidis were inoculated on human tibialis posterior cadaveric tendon to grow biofilms. A low inoculum in 10% growth medium was incubated for 30 min to replicate conditions of clinical infection. Growth conditions assessed included inoculum concentrations of 100, 1000, 10,000 colony‐forming units (CFUs). Tests using the MTS Bionix system were performed to assess the influence of bacterial biofilms on tendon strength. Load‐to‐failure testing was performed on the tendons, and the ultimate tensile strength was obtained from the maximal force and the cross‐sectional area. Displacements of tendon origin to maximal displacement were normalized to tendon length to obtain strain values. Tendon force‐displacement and stress‐strain relationships were calculated, and Young's modulus was determined. Elastic modulus and ultimate tensile strength decreased with increasing bioburden. Young's modulus was greater in uninoculated controls compared to tendons inoculated at 10,000 CFU (p = 0.0011) but unaffected by bacterial concentrations of 100 and 1000 CFU (p = 0.054, p = 0.078). Increasing bioburden was associated with decreased peak load to failure (p = 0.043) but was most significant compared to the control under the 10,000 and 1000 CFU growth conditions (p = 0.0005, p = 0.049). The presence of S. epidermidis increased elasticity and decreased ultimate tensile stress of human cadaveric tendons, with increasing effect noted with increasing bioburden. Clinical Relevance: Understanding the impact of subclinical and chronic infection on mechanical strength following ACLR may reduce graft failure and prolong the integrity of the reconstruction.
