Percutaneous reconstruction of patellar tendon using semitendinosus tendon in chronic patellar tendon injury — case series and outcome

Late reconstruction of the patellar tendon in rheumatoid arthritis using bone-patellar tendon-bone allograft

“…Otherwise, there will be a flexion deficit if the tension is excessive or inability to properly extend if the tension is insufficient [12]. The persistence of patella alta after surgery, as in our case, has been reported [7], [15]. In this regard, it is advisable to assess the normal side through plain radiographs and to measure the patellar indices, such as the Insall-Salvati or Blackburn-Peel index, before the operation.…”

Reconstruction of chronic patellar tendon rupture using graft from contralateral patella graft together with reinforcement from flexor tendons. Case report

“…Jain et al 10 demonstrated improvement in all functional parameters with 80% recovery of quadriceps strength when the reconstruction was performed with flexor tendons in a 4.5-year follow-up. Our choice to combine both techniques aims to sum the positive points of each in a case of chronic rupture with aggressive rehabilitation.…”

“…The first reported cases of delayed repair date back to 1927 and since then, several different techniques and grafts have been reported for this treatment. 1 , 5 , 6 , 8 , 9 , 10 Direct repair, distraction, reinforcement with autograft (contralateral patellar tendon, semitendinosus tendon), allograft (extensor mechanism), Achilles tendon and synthetic materials are technique options that have been described. 5 …”

Patellar tendon: From tendinopathy to rupture

“…All patients had returned to ordinary daily activities. 14 patients were very satisfied, 3 were satisfied, 1 was moderately satisfied, & 1 was unsatisfied Jain et al 79 9 4.5 y Percutaneos semintendinosus reconstruction At Lysholm score & Siwek & Rao grading were good to excellent in all patients, & at 12 months, all patients showed quadriceps strength ≥ 80% of opposite quadriceps …”

“… 76 , 77 , 78 Different variations of the original technique were described, as a percutaneous one or a technique in which the hamstrings were passed through a longitudinal bone tunnel and fixed to the superior pole of the patella with an Endobutton (Smith & Nephew, London, UK). 79 , 80 However, in cases of chronic rupture, the augmentation is always suggested, even in cases in which a primary repair is possible. Figure 2 shows the results of a patellar tendon reconstruction using hamstrings.…”
