Combined All-Inside Anterior Cruciate Ligament Reconstruction and Minimally Invasive Posterolateral Corner Reconstruction Using Ipsilateral Semitendinosus and Gracilis Autograft.

The anterior cruciate ligament (ACL) is the most commonly injured knee ligament, particularly among adolescents and young adults. Unrecognized posterolateral laxity is understood as a major cause of ACL reconstruction failure, and concomitant injury to the posterolateral corner (PLC) is prevalent and underdetected. We advocate screening all ACL-deficient knees for PLC injury and present a technique combining minimally invasive PLC reconstruction with anatomic all-inside ACL reconstruction. The combined procedure uses only the ipsilateral hamstring tendons representing a major surgical advantage over traditional management approaches. The semitendinosus is quadrupled and attached to 2 adjustable suspensory cortical fixation devices to form the ACL graft. The gracilis tendon is looped through the fibula head and secured in a single femoral tunnel for the PLC reconstruction via 2 minimally invasive incisions. The use of a single femoral PLC tunnel combined with a single femoral ACL socket minimizes the risk of tunnel convergence.

Transmedial All-inside TriLink Posterior Cruciate Ligament Reconstruction.

Posterior cruciate ligament (PCL) injuries usually constitute part of a multiligament injury. Isolated PCL injuries account for only approximately 3% of all ligament injuries. No consensus on optimal surgical reconstruction exists. The PCL is a double-bundle structure that functions in an anisometric manner. Biomechanical studies have shown that re-creating the PCL femoral double-bundle configuration provides greater stability. We present a 3-socket approach for an anatomic "all-inside" double-bundle PCL reconstruction using our preferred option of a FiberTape (Arthrex, Naples, FL)-reinforced peroneus longus allograft fashioned to create a trifurcate graft: the TriLink technique. Cortical suspensory fixation devices are used, allowing differential tensioning of the anterolateral and posteromedial bundles. This enables more accurate replication of the native PCL and its biomechanical properties.

Clinical outcomes of anatomic, all-inside, anterior cruciate ligament (ACL) reconstruction.

BACKGROUND: This paper reports the outcomes of patients undergoing ACL reconstruction using a TransLateral single bundle, all-inside hamstring technique at a minimum of two year follow-up. METHODS: The semitendinosus alone is harvested, quadrupled and attached in series to two adjustable suspensory fixation devices. Femoral and tibial sockets are produced using a retrograde drill. The graft is deployed, fixed and tensioned on both tibia and femur. Patients were evaluated preoperatively using the KOOS, Lysholm and Tegner scores and at six, 12 and 24months postoperatively. Objective assessment of knee laxity was performed using the KT-1000 along with goniometric measurement of range or motion. RESULTS: One hundred and eight patients, mean age 30.9years (range 15 to 61) were included. Mean follow-up 49.8months (range 30-66). The mean increase in KOOS at two years was 30.3 points; Lysholm, 33.1 points; Tegner Activity scale, 2.0 levels. These were all statistically significant (p<0.001). Range of motion in the reconstructed knee approximated the uninjured knee by 12months and was restored by two years. KT-1000 showed significant reduction in side-side difference to no more than 2.4mm at all postoperative time points (p<0.001). Re-rupture rate in this series was 6.5%, all following episodes of significant additional postoperative trauma to the knee. CONCLUSIONS: TransLateral all-inside ACL reconstruction demonstrates good medium term subjective and objective outcomes with a low complication and failure rate.

Paediatric ACL repair reinforced with temporary internal bracing.

PURPOSE: Instability following non-operative treatment of anterior cruciate ligament (ACL) rupture in young children frequently results in secondary chondral and/or meniscal injuries. Therefore, many contemporary surgeons advocate ACL reconstruction in these patients, despite the challenges posed by peri-articular physes and the high early failure rate. We report a novel management approach, comprising direct ACL repair reinforced by a temporary internal brace in three children. METHODS: Two patients (aged 5 and 6 years) with complete proximal ACL ruptures and a third (aged seven) with an associated tibial spine avulsion underwent direct surgical repair, supplemented with an internal brace that was removed after 3 months. RESULTS: Second-look arthroscopy, examination and imaging at 3 months confirmed knee stability and complete ACL healing in all cases. Normal activities were resumed at 4 months, and excellent objective measures of function, without limb growth disturbance, were noted beyond 2 years. CONCLUSION: ACL repair in young children using this technique negates the requirement and potential morbidity of graft harvest and demonstrates the potential for excellent outcome as an attractive alternative to ACL reconstruction, where an adequate ACL remnant permits direct repair.
