BACKGROUND: We describe the preliminary clinical results of a patellar stabilization technique to treat bidirectional patellar subluxation (BPS). METHODS: Patients: six patients (one male, five females; mean age 30.2years) underwent this procedure with a minimum of 24months follow-up. Patients were assessed for clinical instability, patellar complications, and need for revision surgery. Patient functional outcomes were evaluated using the criteria of Crosby and Insall and the Kujala Anterior Knee Pain Scale at the time of final follow-up...

INTRODUCTION: The use of the semitendinosus tendon alone for anterior cruciate ligament reconstruction keeps the gracilis muscle intact and decreases anterior pain in comparison with the use of the patellar tendon. Recently, Lubowitz described a new all-inside technique with an ST4 tendon fixed with a cortical button in both femoral and tibial sides. We hypothesized that this type of graft with cortical button fixation provides well-controlled residual anterior tibial translation (<3mm)...

Anterior cruciate ligament (ACL) reconstructive surgeries, employing a total of 48 models, were conducted by virtually removing the ACL and then modeling the surgical preparation, tunnel architecture, graft pre-tensioning and fixation angle of a bone-patellar-tendon-bone autograft. Multifactorial sensitivity analyses were performed to assess the relative influence of these surgical factors on the intraoperative joint laxity, graft-tunnel contact mechanics and graft forces. The sensitivity results indicated that the combined variation in tunnel architecture and graft pre-tension at the time of fixation accounts for most of the estimated variance of the three outcomes...

With the increasing incidence of anterior cruciate ligament (ACL) reconstruction in women and younger patients, the optimal graft choice in the young female patient has become the subject of much debate. This study aimed to evaluate patient-reported outcomes, objective knee stability, complication rates, and the incidence of failure after ACL reconstruction using bone-patellar tendon-bone (BPTB) autograft compared with hamstring (HS) autograft in young female patients. Female patients who underwent primary ACL reconstruction with BPTB or HS autograft between ages 15 and 25 years were identified...

BACKGROUND: Studies establishing the feasibility of anterior cruciate ligament (ACL) reconstruction as an outpatient procedure in France were usually conducted with hamstring tendon grafts. The objective of this study was to evaluate the outcomes of outpatient ACL reconstruction according to whether the graft was harvested from the hamstring tendons or patellar tendon. HYPOTHESIS: Outpatient ACL reconstruction can be performed using any type of graft. METHODS: A single-centre retrospective study was conducted in consecutive patients older than 16 years who had primary ACL reconstruction using patellar tendon or hamstring tendons, with or without lateral tenodesis...

PURPOSE: Revision ACL reconstruction requires careful analysis of failure causes particularly in cases of two previous graft ruptures. Intrinsic factors as excessive tibial slope or narrow femoral notch increase failure risks but are rarely addressed in revision surgery. The authors report outcomes, at minimum follow-up of 2 years, for second revision ACL reconstructions combined with tibial deflexion osteotomy for correction of excessive slope (>12°). METHODS: Nine patients that underwent second revision ACL reconstruction combined with tibial deflexion osteotomy were retrospectively studied...

BACKGROUND: Allograft tissue is a common graft choice for anterior cruciate ligament reconstruction (ACLR). Allograft sterilization methods vary widely across numerous commercial tissue vendors. Multiple studies, despite being limited in sample size, have suggested a higher rate of clinical failure associated with the use of allograft tissue in ACLR when compared with autograft. PURPOSE: To examine the association of graft processing techniques, patient characteristics, and graft type with risk of revision surgery after allograft ACLR...

BACKGROUND: Compared with a patellar tendon autograft (PT), a hamstring tendon autograft (HT) has an increased risk of revision after anterior cruciate ligament reconstruction (ACLR). There are no studies analyzing whether this can be explained by inferior fixation devices used in HT reconstruction or whether the revision risk of ACLR with an HT or a PT is influenced by the graft fixation. PURPOSE: To compare the risk of revision and the revision rates between the most commonly used combinations of fixation for HTs with PTs...
