ConclusionsMeniscal transplantation is clinically effective in treating patients with symptomatic meniscal deficiency. Where indicated, the addition of osteotomy or ACL reconstruction achieves results similar to patients undergoing simple meniscal transplantation in stable and normally aligned knees. Survivorship is lower in patients with full-thickness chondral loss and future treatments should, therefore, be directed at improving success in this at-risk group. The results support encouragement for earlier referral of symptomatic patients to a specialist meniscal reconstruction centre before a significant chondral damage ...

ConclusionMeniscal allograft transplantation in children is founded on the successful results of MAT in the adult population. We have demonstrated in this series that MAT can improve function and reduce pain in the paediatric population, and is, therefore, a viable treatment option for the management of the symptomatic paediatric meniscal-deficient knee. Early referral should be considered in the patients with post-meniscectomy syndrome, pain on weight bearing with a history of previous menisectomy.Level of evidenceIV.

Conclusions: The shortest time to RTS and the highest RTS rate were observed after partial meniscectomy. The time to RTS was shorter, and the RTS rate was higher after meniscal repair than after MAT. Concurrent procedures such as ACLR prolonged the time to RTS, but it had no effect on the RTS rate and the level of sports activity at the time of RTS.

ConclusionsCurrently, indicators like ap-stability after ACL reconstruction or meniscal extrusion represent only indirect measures for biomechanical graft integration. These parameters are at best clinical indicators of allograft function, but the overall integration properties comprising e.g. fixation and graft stiffness remain unknown. Therefore, future research should e.g. focus on advanced imaging techniques or other non-invasive methods allowing for in vivo assessment of biomechanical allograft properties.

AbstractPurposeAim of this study is to document if combined meniscal allograft transplantation (MAT) and ACL reconstruction can improve knee function, reduce pain and allow patients with meniscal defect and ACL lesion to resume sport activities.MethodsFifty MAT, arthroscopically performed without bone plugs and combined with one-stage primary or revision ACL reconstruction, with or without high tibial osteotomy (HTO), were included. Patients (aged 38.2  ± 10.6 years, 87% males) were evaluated at a mean follow-up of 5 years with Lysholm, Tegner and VAS scores. Patient satisfaction was also recorded...

CONCLUSIONS:  The findings of Claes et al reflected a radiographic knee OA prevalence at a minimum average of 10 years' postautologous ACL reconstruction that was lower than commonly perceived (up to 79%). In addition, meniscectomy was an important risk factor (3.54-fold increase) for developing OA after ACL reconstruction. PMID: 26930022 [PubMed - as supplied by publisher]

Discussion Our study has served to gain a better understanding of tendinous allograft bone integration, ligamentization and allograft repopulation. We believe that both cell-based therapies and cell homing therapies are beneficial in ligament tissue engineering. Future studies may elucidate whether cell repopulation occurs with pre-differentiated or progenitor cells. We believe that both cell-based therapies and cell homing therapies are beneficial in ligament tissue engineering. Level of evidence Level V (animal study).

Conclusions: The data of the present study showed that ligamentization did not occur until at least 24 months post-operatively and, during healing, the grafted tendon assumed a unique micro-architecture that was a middle between a tendon and a ligament.The ACL reconstruction in pediatric age has become more frequent in these past recent years. The use of semitendinosus graft with preservation of its distal attachment should be the gold standard in skeletally immature patients.
