Achilles Tendon Allograft

Rupture of the patellar tendon must be diagnosed urgently because reconstruction of the extensor mechanism produces better results when it is performed in acute conditions. Reconstruction of chronic extensor mechanism rupture on the contrary is very challenging. Several surgical techniques have been described using a variety of graft choices and fixation methods, but the optimal approach is still under debate. We report our experience of two cases of chronic patellar tendon rupture reconstruction using an Achilles tendon allograft reinforced by a vascularized ipsilateral semitendinosus tendon frame. The rapid functional recovery of the range of motion, only three months postoperatively, showed us that this reconstruction technique was effective.

<p>Quadriceps tendon rupture is the rarest injury with an incidence of 1.37/1,00,000/year. A patellar fracture is the most common injury associated with extensor mechanism lag, but it is rarely found to have quadriceps rupture rather than patellar tendon rupture. Normally when patella fracture occurs the force is disseminated at the bone level rather than at the muscular level. In this case, the force has disseminated at both muscle and bone leading to fracture of patella and quadriceps tendon rupture. Here we report a case of patellar fracture along with quadriceps tendon rupture.<strong></strong></p>

Achilles Tendon Allograft

This article describes two cases of augmentation of ruptured tendon with fresh frozen Achilles tendon allograft (FFATA) in dogs. Case 1 was a two-year-old crossbreed dog (29 kg) that presented with an open wound on the right forelimb and with complete rupture of the flexor carpi ulnaris and superficial digital flexor tendons. Case 2 was a four-year-old crossbreed dog (4 kg) with partial ruptures of the patellar tendon and detachment of the tibial tuberosity in the right hind limb. In both cases, the ends of the ruptured tendon were sutured and apposed after debridement. To minimize suture failure, FFATA (cut to sufficient size) was placed across the primary suture with tension and sutured to the host tendon. In addition, Case 2 received a Krackow suture through a transverse bone tunnel made in the tibia to fix the patellar tendon along with the tibial tuberosity in situ. The surgical areas healed without any evidence of exaggerated inflammatory response or clinical signs consistent with rejection of the allograft. Both the dogs had normal ambulation and weight bearing on the affected limb 12 weeks postoperatively. No postoperative complications were observed during a one-year follow up period except for slight contracture of the carpus and digits of the affected limb in Case 1. Thus, ruptured tendons can be successfully repaired using suture and augmentation with FFCTA. Augmentation with FFATA may provide additional stability, which counters tension on the primary repair and reduces the chance of gap formation or suture failure in case of reconstruction of the damaged tendon in dogs. &nbsp;
