“…Goizueta etr al 2012 described excellent postoperative results upon disc repositioning in 16 patients using the double suture technique 20 . Recently Yang 2016 and Martín-Granizo 2019 supported their successful arthroscopic discopexy techniques with postoperative MRI evidence on medium and long follow up periods 28,30 Gonçalves et al in 2015 concluded that the validation of the disc repositioning procedure To the best of our knowledge there is no current studies evaluating the efficacy of retrodiscal contracture as a sole step for disc fixation of repositioned stable discs in Wilkes II, and early Wilkes III. This technique was used successfully for dislocation cases by Torres in 2016.…”

“…Both techniques are done under arthroscopic vision with high success rates. Other fixation techniques includes pins [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] All proposed discopexy techniques include disc reduction with or without anterior release followed by retrodiscal contracture and finally disc fixation. In specific cases disc maintains its normal position on top of condyle under function test during the procedure which brings us to think that in such cases retrodiscal contracture shall be enough to maintain disc position with no need for suture, or pin fixation.…”

Statement of the Problem: One of the common surgical procedure for management of mechanical interferences in TMJ is disc repositioning procedure. Disc repositioning for TMJ internal derangement is established procedure with variable success and means of fixation. The purpose of this study is to assess the outcome of using temporomandibular joint (TMJ) arthroscopy disc repositioning with retrodiscal contracture as a minimally invasive surgical treatment for TMJ internal derangement (ID). Materials and Methods: 25 patients, were treated in the period from 2015-2017. All patients were evaluated for changes in preoperative versus postoperative clinical assessment through visual analog scale score (VAS), maximum interincisal opening distance, Joint loading Sign, joint noise and pain, muscle pain, diet and medication intake.Methods of Data Analysis: All patients were followed up for 1 year after treatment. Statistical analyses included the Student t test and Chi square test to determine if there were significant differences in preoperative and postoperative assessments.Results: 25 patients (32 TMJ), the mean age was 39 years; 21 were female and 4 male.13 classified as Wilkes II, 19 as Wilkes III. The success rate was 72% based on improvement of joint pain. The study showed statistically significant improvement in all outcome variables except muscle pain. Conclusion:Clinical outcome data presented show that TMJ arthroscopy disc repositioning with retrodiscal contracture is an effective, predictable surgical treatment. The present study further specifies Wilkes II, early III TMD patients as the most successful category of patients for such procedure.

“…Yang reported better success rates with partial and later complete anterior release of the disc from its anterior attachment and suggested that relapse rates without complete anterior release are high [55]. While more recent success rates of disc repositioning as high as 95.3% [60] have been reported, many of these studies have relatively short-term follow-up and/or no MRI confirmation of longterm stability of the disc repositioning.…”

Temporomandibular joint (TMJ) disorder (TMD) is a broad term encompassing many diseases affecting the TMJ and the surrounding structures and includes internal derangement or disc displacement disorders. Our understanding of internal derangement, its causation, and treatments have evolved over the years, and we are now able to offer effective nonsurgical and surgical management strategies. This chapter will discuss the evolution of our understanding of TMJ internal derangement, diagnosis, causation, and management strategies.

“…The modern temporomandibular joint (TMJ) surgical techniques are progressing to more advanced and minimally invasive treatments, such as TMJ arthroscopic disc repositioning with coblation and suture (Liu et al., 2018). However, classical techniques involving open surgery, such as TMJ discopexy (Abramowicz & Dolwick, 2010; Dolwick, 2001; Hall, 1984; McCarty & Farrar, 1979; Mercuri et al., 1982; Walker & Kalamchi, 1987) and TMJ discectomy (Bjørnland & Larheim, 2003; Candirli et al., 2017; Miloro et al., 2017) still play an important role on severe joint dysfunction cases.…”

The effort to develop an effective and safe temporomandibular joint (TMJ) disc substitute has been one of the mainstreams of tissue engineering. Biodegradable customized scaffolds could approach safety and effectiveness to regenerate a new autologous disc, rather than using non‐biodegradable materials. However, it is still technically challenging to mimic the biomechanical properties of the native disc with biodegradable polymers. In this study, new 3D tailored TMJ disc implants were developed: (1) Poly(glycerol sebacate) (PGS) scaffold reinforced with electrospun Poly(εcaprolactone) (PCL) fibers on the outer surface (PGS+PCL); (2) PCL and polyethylene glycol diacrylate (PEGDA) (PCL+PEGDA); and (3) PCL. The TMJ implants were tested in a randomized preclinical trial, conducted in 24 black Merino sheep TMJ, perfoming bilateral interventions. Histologic, imaging, and kinematics analysis was performed. No statistical changes were observed between the PGS+PCL disc and the control group. The PCL+PEGDA and PCL groups were associated with statistical changes in histology (p = 0.004 for articular cartilage mid‐layer; p = 0.019 for structure changes and p = 0.017 for cell shape changes), imaging (p = 0.027 for global appreciation) and dangerous material fragmentation was observed. No biomaterial particles were observed in the multi‐organ analysis in the different groups. The sheep confirmed to be a relevant animal model for TMJ disc surgery and regenerative approaches. The PCL and PCL+PEGDA discs presented a higher risk to increase degenerative changes, due to material fragmentation. None of the tested discs regenerate a new autologous disc, however, PGS+PCL was safe, demonstrated rapid resorption, and was capable to prevent condyle degenerative changes.
