Reconstruction • 6- to 10-mm increased lateral tibiofemoral joint opening 20 degrees of flexion • ≥15 degrees increased external tibial rotation 30 degrees, 90 degrees of flexion • ± Varus recurvatum, standing and supine • ± Hyperextension gait abnormality • Double or triple varus knee, after osteotomy • Acute injuries, bony avulsions amendable to internal fixation INDICATIONS The primary soft tissue–stabilizing structures of the posterolateral (PL) aspect of the knee joint are the fibular collateral ligament (FCL) and popliteus muscle-tendon-ligament unit (PMTL), including the popliteofibular ligament (PFL) and posterolateral capsule (PLC) shown in Figure 17-1 These structures function together to resist lateral joint opening (LJO), posterior subluxation of the lateral tibial plateau with tibial rotation, knee hyperextension, and varus recurvatum.13,14,38,39,55,64 The mechanism of injury may be contact or noncontact and usually involves a combined varus and hyperextension joint displacement The proper management of injuries involving the PL structures requires knowledge of the complex anatomy and potential variations that may exist, the function of the major soft tissue stabilizers, appropriate diagnostic techniques, and surgical options for reconstruction Isolated PL injuries are rare; however, on occasion an avulsion fracture at the femoral attachment occurs requiring internal fixation.29 PL injuries are frequently accompanied by anterior cruciate ligament (ACL) or posterior cruciate ligament (PCL) ligament ruptures.1,3,9,28 Although the incidence of PL injury is unknown (owing to misdiagnosis or failure to detect the injury), the consequences of untreated PL ruptures are readily apparent Chronic deficiency of the PL structures may be a factor in the failure of cruciate reconstructions43,44,49 and 527 528 CHAPTER 17  Posterolateral Ligament Injuries CRITICAL POINTS  Contraindications Lateral gastrocnemius tendon Popliteofibular

10 mm A Normal lateral joint opening (30°) Varus load mm B C FIG 17-2  The gap test A, The amount of lateral tibiofemoral joint opening is measured with the knee at 25 degrees of flexion Knees with insufficiency of the posterolateral structures will demonstrate 12 mm of joint opening at the periphery of the lateral tibiofemoral compartment, 10 mm at the midportion of the compartment, and 8 mm at the innermost medial edge B, Normal gap test C, Abnormal gap test The position of the medial and lateral tibial plateau is assessed at the starting position (neutral tibial rotation) with the knee flexed to 30 and 90 degrees and at the final position with the tibia in maximal external rotation The examiner palpates the position of the medial and lateral tibial plateau, which is compared with the normal knee to assess whether a subluxation (anterior or posterior) of the medial or lateral tibial plateau is present An increase in internal tibial rotation occurs with both lateral ligament, medial ligament, and PCL disruption (see Chapter 15) The axis of tibial rotation is observed in the involved knee and compared with the normal knee to detect a shift in the medial or lateral tibiofemoral compartment during tibial rotation It is not recommended that the dial test be performed in the prone position because the tibiofemoral joint cannot be accurately palpated to distinguish an anteromedial from a PL tibial subluxation It is not possible to clinically determine the actual millimeters of translation of the medial and lateral tibial plateaus in reference to the femoral condyle A qualitative determination is made of the anterior or posterior subluxation of the medial or lateral tibiofemoral joint CHAPTER 17  Posterolateral Ligament Injuries With PL injuries, there is an abnormal lateral deviation of the tibial tubercle in the dial test compared with the opposite knee The use of the dial test in knees with PCL ruptures requires maintenance of a normal anatomic tibiofemoral position This is accomplished by applying an anterior translation, loading the ACL in both limbs, during the external tibial rotation It is still necessary to use the supine position so that the examiner can palpate the tibiofemoral position.61 The dial test is less accurate with a PCL rupture because it is difficult to compare limbs, and other tests to be described (LJO, gap test at arthroscopy, varus recurvatum) for the integrity of the PL structures need to be carefully assessed When a posterior subluxation of the lateral tibial plateau is positively identified by the tibiofemoral rotation test, additional tests must be conducted to determine the integrity of other ligament structures The amount of LJO at and 20 degrees of knee flexion should be determined to further assess the integrity of the FCL and other secondary ligament restraints The posterior tibial subluxation of the central tibial and medial tibiofemoral joint determines the amount of increased translation because of a PCL injury, which adds to the maximum posterior subluxation to the lateral compartment with external tibial rotation The presence of a varus recurvatum in both the supine and standing positions must be carefully assessed Often, the varus recurvatum reaches its maximum position when the patient is standing and asked to maximally hyperextend both knees The appropriate tests to determine the integrity of the ACL and PCL are performed, including KT-2000 (MEDmetric) arthrometer testing at 20 degrees of flexion (134 N) to quantify total anteroposterior (AP) displacement The pivot shift test is recorded on a scale of to III (grade 0, no pivot shift; grade I, slip or glide; grade II, jerk or clunk; grade III, gross subluxation with impingement of the PL aspect of the tibial plateau against the femoral condyle) A misdiagnosis of a positive pivot shift test may occur with PL injuries as the lateral tibial plateau is brought to a reduced position (starting from a posterior subluxated position) with knee extension and then posteriorly subluxates with knee flexion (reverse pivot shift test) The medial posterior tibiofemoral step-off on the posterior drawer test is done at 90 degrees of flexion Radiographs taken during the initial examination include AP, lateral at 30 degrees of knee flexion, weight-bearing PA at 45 degrees of knee flexion, and patellofemoral axial views Lateral stress radiographs may be required of both knees (20 degrees of flexion, neutral tibial rotation, and 67-N varus force) A comparison is made of the millimeters of lateral tibiofemoral compartment opening between knees A lateral radiograph is used to determine the approximate length required for FCL anatomic grafts The distance from the anatomic femoral insertion site to the anatomic fibular insertion site is measured and adjusted for magnification A measurement of the patellar tendon length is also made when a bone-patellar tendon-bone (B-PT-B) FCL autograft is planned; however, in most knees, a B-PT-B allograft is used, as will be discussed Posterior stress radiographs are obtained in patients with PCL ruptures, especially those in which the distinction of a partial versus complete PCL deficiency is difficult to determine on clinical examination.15 A lateral PCL stress radiograph is taken of each knee at 90 degrees of flexion The limb is placed in neutral rotation with the tibia unconstrained and the quadriceps relaxed, and 89-N force applied to the proximal tibia Measurement is made of the millimeters of posterior tibial translation in both knees Knees with 10 mm or more of increased posterior tibial translation are considered candidates for PCL reconstruction Full standing radiographs of both lower extremities, from the femoral heads to the ankle joints, are done in knees with varus lower 535 extremity alignment The mechanical axis and weight-bearing line are measured to determine whether HTO is indicated.11 Patients complete questionnaires and are interviewed for the assessment of symptoms, functional limitations, sports and occupational activity levels, and patient perception of the overall knee condition according to the Cincinnati Knee Rating System (CKRS; see Chapter 41).2 CLASSIFICATION AND TREATMENT OF PARTIAL TO COMPLETE PL INJURIES The classification and treatment of first-, second-, and third-degree acute PL injuries are detailed in Table 17-2 It is important to diagnose partial tears of the PL structures, with a mild to moderate increase in LJO and external tibial rotation, to allow protection and maintain lateral tibiofemoral joint closure in the initial weeks to allow “stick-down” and healing of lateral soft tissues This is a program similar to that recommended for medial ligament ruptures (see Chapter 19) PREOPERATIVE PLANNING: TIMING OF SURGERY Acute Injuries There is a distinct advantage for repairing completely disrupted PL structures and meniscal attachments in acute injuries (Fig 17-3) At the time of surgery, extensive disruption of these structures is observed Careful dissection is required to identify anatomic tissue planes and maintain an intact vascular and neural supply The so-called golden period to perform an acute surgical repair is within to 14 days of the injury After this time, scar tissue will obliterate tissue planes and make the dissection and repair difficult A lower extremity venous ultrasound is obtained before surgery in acute multiligament knee injuries that have swelling and soft tissue damage to detect occult venous thrombosis that requires urgent treatment and contraindicates surgery An initial delay in surgery for to days allows for observation of the neurovascular status, soft tissue swelling, skin integrity, and some clearing of hemorrhage in soft tissues in the injured extremity During this time, the lower extremity is supported in a soft-hinged full-leg brace in extension with a well-padded compression dressing In knees with extensive damage to the PL structures and PCL, a bivalved cylinder cast with a posterior plaster shell and posterior foam calf pad may be required to provide added stability and prevent posterior tibial subluxation Reduction of the tibiofemoral joint is verified by a lateral radiograph Lower limb elevation, ice, and compression are important The physical therapist initiates early protected knee motion, patellar mobilization, active quadriceps function, and electrical muscle stimulation Dislocated knees scheduled for surgery require vascular consultation, ankle/brachial studies (ankle/brachial index ≥90%), and possible arteriography to exclude arterial injuries, even when intact peripheral pulses are present Contraindications to acute surgical repair are excessive soft tissue swelling, hemorrhage, and edema that are frequently present in dislocated knees with multiple ligament ruptures The operative procedure adds to the injury by increasing edema and soft tissue swelling, risk of infection, vascular problems (including compartment syndromes), and skin flap necrosis In these cases, it is preferable to treat the acute injury and perform ligament reconstructive procedures later after tissue swelling is resolved and muscle function and knee motion have been restored In addition, there is a significant incidence of knee arthrofibrosis after acute surgical treatment of knee dislocations, which is lessened 536 CHAPTER 17  Posterolateral Ligament Injuries TABLE 17-2  Diagnosis and Classification of Acute Posterolateral Injuries First Degree Anatomic

Acute Injuries • Golden period acute surgical repair: 7-14 days after injury • Lower extremity venous ultrasound, vascular consult for multiple ligament ruptures • Delay surgery 5-7 days, observe neurovascular status, soft tissue swelling, skin integrity • Soft hinged full-leg brace, well-padded compression dressing • PCL rupture: bivalved cast with posterior plaster shell, posterior calf pad • Verify tibiofemoral reduction with lateral radiograph in multiligament injuries • MRI for location of major ligament disruptions • Protected knee motion, patellar mobilization, isometrics • Contraindications to acute surgery in dislocated knees: excessive soft tissue swelling, hemorrhage, edema Delay reconstruction until swelling resolved, muscle function and knee motion restored Chronic Injuries • Muscle atrophy requires preoperative rehabilitation • Hyperextension gait abnormality requires gait-retraining program before PL reconstruction • Varus osseous malalignment requires osteotomy before PL reconstruction • Absent lateral meniscus, early tibiofemoral arthritis, consider lateral meniscus transplant Cruciate Graft Reconstruction • Ensure B-PT-B, Achilles tendon allografts available • Determine appropriate grafts for ACL or PCL reconstruction ACL, Anterior cruciate ligament; B-PT-B, bone-patellar tendon-bone; MRI, magnetic resonance imaging; PCL, posterior cruciate ligament; PL, posterolateral with a staged approach In our experience, the majority of multiligament disruptions in dislocated knees are not candidates for acute surgical procedures A delay in surgical reconstruction results in a decreased incidence of knee arthrofibrosis and markedly improves surgical outcomes Other obvious contraindications include open wounds and skin abrasions Magnetic resonance imaging (MRI) provides important information regarding ligament ruptures, articular cartilage damage, and meniscus tears Frequently, the sites of rupture to the FCL, popliteus muscle and tendon, PFL, and meniscal attachments may be identified before surgery One note of caution is the edema and swelling in the PL tissues leads to a conclusion of greater tissue damage and disruption than what is actually encountered at surgery Chronic Injuries Patients with chronic knee injuries often present with severe lower limb muscle atrophy requiring months of preoperative rehabilitation Patients with a hyperextension gait abnormality must complete a gait retraining program50 described in detail in Chapter 29 This program is done in addition to lower extremity muscle strengthening exercises In our experience, patients will convert to a more normal gait pattern after to weeks of training Varus osseous malalignment must be corrected before chronic PL reconstruction, as described previously Failure to address varus malalignment will greatly increase the risk of failure of any PL procedure (Fig 17-4) In anatomic PL reconstructions, the ligament surgery is staged after healing of the HTO The indications for the various PL procedures are described in detail under the “Operative Treatment of Acute Posterolateral Ruptures” and “Operative Treatment of Chronic Posterolateral Ruptures” sections Patients who have undergone prior lateral meniscectomy and who demonstrate early tibiofemoral arthritis are considered for a staged lateral meniscus transplantation after the PL reconstruction.48 INDEX Anterior-posterior translation, during normal walking, 131-132, 131f Anteroinferior popliteomeniscal fascicle, 31f Anterolateral ligament (ALL), 23-26, 27f-28f
