Objective: To evaluate the clinical outcome of arthroscopically assisted combined anterior and posterior cruciate ligament (ACL/PCL) reconstructions using Achilles tendon-bone allografts.
Methods: Associated meniscus injuries were treated according to established methods prior to ligament reconstructions during arthroscopic surgery. Thirty Achilles tendon-bone allografts were used to reconstruct torn ACL and PCL in 15 knees. At postoperative follow-up, all knees were graded using the modified IKDC and the Lysholm scoring systems just as done preoperatively.
Results: were analyzed compared with the contralateral healthy knees. Results: Eleven men and 4 women with a minimum of 3-year follow-up (mean 38 months) were included in the study. Preoperatively, the group ratings by the modified IKDC standards were all severely abnormal. Twelve bicruciate reconstructions were performed in subacute or chronic stage (larger than 3-8 weeks), 3 for acute ligamentous deficiencies (less than or equal to 3 weeks). The noticeable early complication was transitory local fever combined with joint effusion in one case. At postoperative follow-up, 9 knees were normal, 5 nearly normal and 1 abnormal. On Lysholm score the difference was statistically significant (t- test, P less than 0.001) before and after operation.
Conclusions: Achilles tendon-bone allograft offers an alternative for simultaneous arthroscopic ACL/PCL reconstructions. However, further investigation is needed to eradicate its potential immunogenicity for better use.

Anterior cruciate ligament reconstruction is one of the most common orthopaedic sports medicine surgeries. Its prevalence in the sports medicine sphere is matched by the numerous options of different techniques. Chief among these is graft selection, which most commonly falls into 1 of 4 options: bone-patellar tendon-bone (BPTB) autograft, hamstring tendon autograft (HT), quadriceps tendon autograft, and allografts.

Article Synopsis
- * This scaffold consists of three components: a porous structure for bone, a hydrogel for cartilage, and oriented fibers for tendon, all engineered to promote cell differentiation and healing.
- * Results show that the scaffold not only matches the mechanical properties of TBI but also enhances the healing process in a rat model, indicating its potential for effective TBI regeneration.

Article Synopsis
- Calcanectomy and Achilles tendon resection are complex procedures, but Ilizarov's technique allows for the reconstruction of the calcaneus while preserving the ankle joint.
- A case study of a 25-year-old motorcyclist who underwent significant surgeries showed a marked improvement in function, with an AOFAS score increase from 35 to 70 over 12 years and nearly complete recovery of plantar flexion strength.
- This innovative approach demonstrated that even after substantial muscle disconnection, it is possible to restore almost full push-off force using a fresh-frozen tendon-bone allograft, despite the neo-calcaneus being smaller than normal.

Objective: To describe a novel, dynamic ultrasound assessment of the Achilles tendon at the calcaneal insertion taking advantage of the effusion within the deep retrocalcaneal bursa as a natural contrast agent.
Materials And Methods: Positioning the ultrasound transducer in a longitudinal plane over the Achilles tendon at the calcaneal insertion, manual compression of the deep retrocalcaneal bursa can be performed using the other hand. Dynamically shifting the anechoic effusion from the proximal to the distal compartment of the bursa, the undersurface of the Achilles tendon is lifted from the underlying cortical bone of the superior facet of the calcaneal tuberosity.
