Single Femoral Socket Double-Bundle Anterior Cruciate Ligament Reconstruction Using Tibialis Anterior Tendon: Description of a New Technique

The native anterior cruciate ligament (ACL) has been shown to consist of 2 functional bundles with independent behavior throughout range of knee motion. Conventional arthroscopic ACL reconstruction techniques selectively recreate the anteromedial bundle of the native ACL only. Numerous studies have reported the failure to restore normal knee kinematics in an ACL-deficient knee using a single-bundle reconstruction. It has been suggested that by reconstructing both the anteromedial and posterolateral bundles of the ACL, more normal knee kinematics may be achieved. Several authors have described surgical techniques to recreate the 2 functional bundles and they range from using 2 femoral tunnels to using a single femoral tunnel with the other bundle passed over the top. This article describes a new technique of recreating the 2 functional bundles of the ACL with tibialis anterior tendon allograft using a single femoral socket.     

Editorial Commentary: Arthroscopy Is the Gold Standard for Diagnosis of Meniscal Ramp Lesions: Magnetic Resonance Imaging Also May Be Helpful

Identifying and treating medial meniscal ramp lesions in conjunction with ligament reconstruction restores critical stability in knees with ligament injuries. This must begin with obtaining high-quality magnetic resonance imaging (MRI) and critical evaluation of the MRI and include a subsequent thorough arthroscopic examination of these knees. As evident in previous studies, most surgeons associate medial meniscal ramp lesions with anterior cruciate ligament (ACL) tears. Biomechanical studies have reported that a ramp lesion produces significant anterior tibial translation and external rotational instability in ACL-deficient knees that is not reestablished with an isolated ACL reconstruction. In addition, recent research identified ramp lesions in one-third of multiligament knee injuries with an intact ACL and two-thirds of patients with posteromedial tibial plateau bone bruises on MRI. Restoring knee stability and biomechanics is necessary in treating all knee ligament injuries. Don’t miss the meniscal ramp lesion. Have a high index of suspicion, obtain a high-quality MRI,and arthroscopically evaluate the meniscocapsular junction of the medial meniscus, especially if there is a bone bruise seen on MRI.     

Age and ACL reconstruction revisited

To determine the age limitations for indicating ACL reconstructions in patients with functional instability, this article reviews the results of anterior cruciate ligament (ACL) reconstructions in 23 patients with an average age of 54 years (range: 49-64 years). Patients were evaluated with the Lysholm and Gillquist knee questionairre, visual analog scale, satisfaction rating, physical examination, KT-1000 testing, and radiographs. Nineteen of the 23 patients were available for follow-up at an average of 24 months after the index procedure. Sixteen patients returned for physical examination and 3 agreed to telephone interviews. The mean Lysholm score was 92, visual analog score 0.5, satisfaction rating 100%, KT-1000 testing 2mm, range of motion 0 degrees to 135 degees. Sixteen of the 19 patients returned to acceptable activity levels. Fifteen patients had excellent or good results, while 4 patients had fair or poor results. Three of the 4 fair or poor results had significant moderate or severe knee arthrosis. Anterior cruciate ligament reconstruction with allograft in 49-64 year-old patients with minimal arthrosis is a safe, minimally invasive procedure that allows for return to a desired level of activity.     

Assessment of the endoscopic semitendinosus/gracilis autograft procedure with interference screw fixation for reconstruction of the anterior cruciate ligament

The semitendinosus/gracilis autograft procedure with interference screw fixation was evaluated for clinical effectiveness of anterior cruciate ligament (ACL) reconstruction. Thirty patients underwent the procedure and were evaluated an average of 15 months postoperatively. Results revealed 22 (73%) patients had a standard knee evaluation form score of normal or nearly normal, and 24 (80%) patients returned to strenuous or moderate activity levels. Average Lysholm outcome score was 89, and bilateral KT-2000 differences were <3 mm at follow-up. Functional knee test symmetry index percentage outcome for the one-legged hop test was 92.6% for distance and 98% for time. Length of time (i.e., < or =90 days or > or =91 days) between injury and surgery was independent of outcome. These findings indicate the semitendinosus/gracilis autograft is a viable procedure for reconstruction of the ACL-deficient knee.     

Management of the dislocated/multipleligament injured knee

The multiple ligament injured knee is a complex problem in orthopaedic surgery. Most dislocated knees involve tears of the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), and at least one collateral ligament complex. Careful assessment of the vascular status of the extremity is essential because of the possibility of arterial and/or venous compromise. These complex injuries require a systematic approach to evaluation and treatment. Physical examination and imaging studies enable the surgeon to make a correct diagnosis and to formulate a treatment plan. Arthroscopically assisted combined ACL/PCL reconstruction is a reproducible procedure. Knee stability is improved postoperatively when evaluated using knee ligament rating scales, arthrometer testing, and stress radiographic analysis. Acute medial cruciate ligament tears, when combined with ACL/PCL tears, may, in certain cases, be treated with bracing. Posterolateral corner injuries combined with ACL/PCL tears are best treated with primary repair as indicated combined with reconstruction using a post of strong autograft (split biceps tendon, biceps tendon, semitendinosus) or allograft (Achilles tendon, bone patellar tendon bone) tissue. Surgical timing depends on the ligaments injured, the vascular status of the extremity, reduction stability, and the overall health of the patient. We prefer the use of allograft tissue for reconstruction in these cases because of the strength of these large grafts and the absence of donor site morbidity.

Editorial Commentary: Ligamentous Hyperlaxity: A Decisive Factor for the Indication of a Combined Anterior Cruciate Ligament and Anterolateral Ligament Reconstruction?

Indications for combined anterior cruciate ligament (ACL) and anterolateral ligament (ALL) reconstruction are not well defined, and the role of ligamentous hyperlaxity on anterolateral rotatory instability in an ACL-deficient knee remains unclear. Possible indications for combine ACL and ALL reconstruction might be a high-grade pivot shift, revision ACL reconstruction, patients with proven anterolateral knee pathology on preoperative imaging, and young patients participating in high-demand sport, and perhaps, finally, patients with ligamentous hyperlaxity as above.     

Characteristics of anterior tibial translation with active and isokinetic knee extension exercise before and after ACL reconstruction

 The aim of this study was to investigate the biomechanical characteristics of anterior tibial translation (ATT) in anterior cruciate ligament (ACL)-deficient or -reconstructed knees with active and isokinetic knee extension exercise. Forty-nine patients with unilateral isolated ACL-deficient knees were enrolled. Follow-up examinations were carried out at a mean of 24 months postoperatively. An electrogoniometer system was applied to compare the amount of ATT in ACL-deficient and -reconstructed knees. For both active and isokinetic knee extension, the mean ATT of ACL-deficient knees was considerably greater than that for the normal side, within a range of flexion 0°–70° and 0°–60°, respectively. In contrast, no mean ATT differences were seen during both active and isokinetic exercise from 90° to 0° at follow-up. Within a range of flexion between 50° and 70°, the side-to-side difference in ATT with active knee extension was significantly greater than that with isokinetic extension in ACL-reconstructed knees. These results suggest that the amount of ATT is significantly improved with both active and isokinetic exercise, postoperatively. However, postoperative ATT with isokinetic extension is smaller than that with active knee extension from 50° to 70°. Received: October 17, 2001 / Accepted: December 26, 2001

Anterior cruciate ligament reconstruction and knee osteoarthritis

Anterior cruciate ligament(ACL)injury is a traumatic event that can lead to significant functional impairment and inability to participate in high-level sports-related activities.ACL reconstruction is considered the treatment of choice for symptomatic ACL-deficient patients and can assist in full functional recovery.Furthermore,ACL reconstruction restores ligamentous stability to normal,and,therefore,can potentially fully reinstate kinematics of the knee joint.As a consequence,the natural history of ACL injury could be potentially reversed via ACL reconstruction.Evidence from the literature is controversial regarding the effectiveness of ACL reconstruction in preventing the development of knee cartilage degeneration.This editorial aims to present recent highlevel evidence in an attempt to answer whether ACL injury inevitably leads to osteoarthritis and whether ACL reconstruction can prevent this development or not.     

Isolierte und kombinierte Kniebandverletzungen

Complex knee ligament injuries are characterized by simultaneous rupture of the anterior cruciate ligament (ACL) and/or the posterior cruciate ligament (PCL) and at least one collateral ligament. Isolated injury to the medial collateral ligament (MCL) and PCL have a high healing capacity and can be treated conservatively in many cases. Ruptures of the MCL can also be treated conservatively in complex injuries if the cruciate ligaments are reconstructed. Ruptures of the lateral structures usually need surgical reconstruction. Indications for acute surgical repair include meniscus dislocation, entrapment of collateral ligament portions in the joint, knee dislocation with severe knee instability, and displaced bony avulsions. The anatomy of the knee ligaments must be carefully respected in surgical reconstruction. Acute repair of collateral ligament injuries is possible only in the first 2 weeks after trauma. Acute arthroscopy is indicated only in combination with reconstructive surgery.     

Early ACL reconstruction in combined ACL-MCL injuries

This study reports 18 patients with 19 combined ligament injuries with complete anterior cruciate ligament (ACL) tear and a minimum grade II medial collateral ligament (MCL) tear who underwent early reconstruction of the ACL and nonoperative treatment of the MCL. Inclusion criteria included ACL reconstruction performed within 3 weeks of initial injury, no history of antecedent injury to the ipsilateral knee, and 2-year follow-up data. Associated injuries were noted in 11 patients including 6 isolated lateral meniscal tears, 1 isolated medial meniscal tear, 5 combined meniscal tears, 1 chondral injury, and 1 patellar fracture. Subjective minimum 2-year follow-up yielded a mean Lysholm score of 94.5 and a mean Tegner activity score of 8.4. Serial clinical examinations demonstrated good functional outcomes, range of motion, and strength. No patient experienced ACL graft failure or valgus instability or required subsequent surgery for chondral or meniscal damage. One patient required a second surgery for arthrofibrosis. Clinical and functional outcomes in this study were good with low motion complication rates. Based on our data, early surgical reconstruction of the ACL and nonoperative treatment of the MCL in combined injuries is acceptable and results in excellent clinical and functional outcomes.

Valgus osteotomy with anterior cruciate ligament laxity.

Some patients with medial joint degeneration post-medial meniscectomy also have a significant anterior cruciate ligament (ACL) instability. Ten patients were treated by a combined high tibial valgus osteotomy with ACL reconstruction. All patients had relief of instability and decreased pain, although only one returned to full activity. The operation is recommended as a salvage procedure for an ACL deficient knee with instability and medial joint degeneration.

Revision anterior cruciate ligament reconstruction: etiology of failures and clinical results

A retrospective study was performed to determine the etiology of failed primary anterior cruciate ligament (ACL) reconstruction and evaluate the clinical results of revision ACL surgery. From January 1989 to January 1996, 90 patients with failed ACL reconstructions underwent revision ACL surgery. The etiology of failed ACL reconstruction included 47 surgical technical errors, 22 traumatic reinjuries, 7 lack of graft incorporation, 3 loss of motion, 3 related to synthetic grafts, and 8 alignment or combined ligamentous instability patterns not addressed. Of 52 revision ACL patients with minimum 2-year follow-up, 43 responded to a questionnaire and underwent a comprehensive physical examination. The Hospital for Special Surgery knee ligament evaluation revealed 63% good/excellent results. Objective laxity test revealed 77% of all patients had 0/+1 grade on Lachman and a mean 2.86-mm KT 1000. The overall results of revision ACL surgery are encouraging in providing symptomatic relief and restoring stability; however, they are significantly lower than primary ACL surgery.
