“…Clinically, the involved knees did as well as those in other stud-ies in the literature with regard to postoperative Lysholm scores, ROM, and other parameters. [7][8][9][10] To the authors' knowledge, one other report exists on the outcome of the AperFix System for ACL reconstruction. Uzumcugil et al 9 compared the outcomes of the TransFix fixation method (Arthrex Inc, Naples, Florida) and the AperFix System after arthroscopic ACL reconstruction.…”

“…9 Tunnel widening has been recognized as a potential problem with certain types of fixation systems. 7,8,13,14 Possible causes of widening include heat necrosis from tunnel drilling, movement of the graft inside the tunnel, location of fixation points with respect to the articular surface, and nonspecific inflammatory response. Most studies in the literature report no clinical effect of widening.…”

“…The extent of tunnel widening observed in the current study's patients was consistent with that in previous reports. 14 Various material properties of a PEEK implant may provide a favorable biomechanical environment, lessening the propensity for conditions leading to tunnel widening 5 ; however, this was not evident in the study performed by Uzumcugil et al 8 Further study is necessary to determine if the use of a hybrid graft may promote earlier healing of the graft to femoral tunnel walls, resulting in better overall stability and discouraging conditions favorable for widening.…”

The purpose of the study was to assess the fixation durability of the AperFix System (Cayenne Medical, Inc, Scottsdale, Arizona) used in arthroscopic reconstruction of the anterior cruciate ligament. The AperFix System consists of a femoral and tibial component designed to secure either allograft or autograft. The outcomes of 185 knees (180 patients) were retrospectively reviewed at a minimum of 2 years postoperatively. Mean age at surgery was 31±12 years (range, 16-68 years). Of these, a convenience sample was seen prospectively to obtain radiographs and to assess functional status. No cases occurred of fixation failure involving loss of graft positioning or pullout. No patients required revision anterior cruciate ligament reconstruction. In 2 knees, the tip of the central fixation pin had to be modified as a result of hardware prominence and soft tissue irritation at 434 and 159 days postoperatively, respectively. In 4 knees, tibial screw removal occurred secondary to local discomfort (mean, 239 days; range, 105-371 days). No other recurring adverse events or problems associated with the implants were identified. Forty-four patients were evaluated prospectively at a mean follow-up of 32±7 months. Lysholm scores and patient satisfaction scores were positively and significantly correlated with Tegner activity scores (r=0.61; P<.0001). Eighty-two (82%) patients had a KT-1000 (Medmetric Corp, San Diego, California) side-to-side difference of less than 3 mm (average, 0.4 mm). No indications of femoral device migration existed when comparing follow-up and immediate postoperative radiographs. The AperFix System provides durable femoral aperture fixation during anterior cruciate ligament reconstruction with excellent clinical outcome scores and a low complication rate.

“…Since first introduced in the 1990s by AcroMed, PEEK has been widely used in spine, orthopedics, and arthroscopy surgery because of its chemical resistance, mechanical properties, and imaging characteristics (Kurtz & Devine, 2007;Uzumcugil, Yalcinkaya, Ozturkmen, Dikmen, & Caniklioglu, 2012).

“…Polyetheretherketone (PEEK) is a semicrystalline thermoplastic material that is produced from the step-growth alkylation reaction of bisphenolates. Since first introduced in the 1990s by AcroMed, PEEK has been widely used in spine, orthopedics, and arthroscopy surgery because of its chemical resistance, mechanical properties, and imaging characteristics (Kurtz & Devine, 2007;Uzumcugil, Yalcinkaya, Ozturkmen, Dikmen, & Caniklioglu, 2012). PEEK's modulus of elasticity is 3.6 GPa, which can be increased to 18 GPa by reinforcing it with carbon fibers, leading it to be more closer to that of cortical bone (18 GPa) than Ti alloys (~110 GPa) (Ponnappan et al, 2009;Ramakrishna, Mayer, Wintermantel, & Leong, 2001).…”

Long-term and stable fixation of implants is one of the most important points for a successful orthopedic surgery in the field of endoprosthesis. Osseointegration (OI), functional connection between bone and implants, is considered as a pivotal process of cementless implant fixation and integration, respectively. OI is affected by various factors of which the property of implants is of high significance. The modification of implants surface for better OI has raised increasing attention in modern orthopedic medicine. Here, the process of OI and the interactions between implants and ambient bone tissues were emblazed. The knowledge regarding the contemporary surface modification strategies was systematically analyzed and reviewed, including materials used for the fabrication of implants, advanced modification techniques, and key factors in the design of porous implants structure. We discussed the superiority of current surface modification programs and concluded that the problems remain to be solved. The primary intention of this systematic review is to provide comprehensive reference information and an extensive overview for better fabrication and design of orthopedic implants.
