Discharge criteria after PCL reconstruction is based on patient goals for athletics and occupations and the rating of symptoms, stress radiography (90° flexion), KT-2000 testing, muscle strength testing, and function testing (Table 23-2). /KJæb¤ð(ÆâåYÓ"+óv£Uû½Q¦›—Ùç¾,j¦Uzׯ€Á¢(†  Æ®ëZ§,1èL‘Ü÷ƒÿò¿;“QgòÐq¬Û;çÝ>e©:2-ÓdmÕÈ:WçØóÆ*öÆΛ0öf£ó™&'œ"Í{¯€T[üTgÎáXCþ1;M¼ìÇ>lÞ?§ºæ7°ïçz›Éä Øžƒ The most common intraoperative complications concern neurovascular injury, particularly involving the popliteal artery. PCL (posterior cruciate ligament) reconstruction. Because of this, some authors recommend routine ligation of the inferior medial geniculate vessels.16 Postoperatively, residual laxity, loss of motion or arthrofibrosis, infection, painful hardware, and anterior knee pain are the most common complications. Begin quadriceps muscle strengthening 5. Loss of motion is not uncommon and is often related to excessive graft tension, tensioning in extension, and inadequate postoperative rehabilitation. row) during all-inside posterior cruciate ligament (PCL) reconstruction. Posterior cruciate ligament (PCL) surgical reconstructions may be unsuccessful because of failure to recognize and treat associated ligament instabilities (posterolateral instability and posteromedial instability), failure to treat varus osseous malalignment, and incorrect tunnel placement. Reconstructed PCL knees may be slow to regain full flexion; this may be worsened by poor tunnel placement.6 As importantly, patient age, severity of trauma, and ability to actively rehabilitate are important factors often beyond the surgeon's control. The PCL reconstruction rehabilitation is unique in that extreme knee flexion places We prefer to take advantage of the tibial sagittal slope, which results in anterior tibial translation with weight bearing. ligament of Humphrey (anterior) and ligament of Wrisberg (posterior) originate from the posterior horn of the lateral meniscus and insert into PCL substance; Blood supply . A structured physical therapy program is essential to regaining motion, strength, and proprioception. Ensure wound healing 3. PCL tears occur due to trauma, such as automobile accidents, or falling on the knee when bent. The focus of this rehab protocol is on Decrease knee and leg swelling 7. Fig 5. Advanced symptomatic patellofemoral or tibiofemoral arthritis is a frequent contraindication. However, isolated PCL injuries are relatively infrequent. Posterior Cruciate Ligament Rehabilitation Protocol **It is important to understand that all time frames are approximate and that progressions should be based on individual monitoring. In brief the principles are: • Weight Bearing: Partial weight bearing for 6 weeks then build to full weight bearing by 8 weeks. Factors contributing to this include the fact that the PCL has a complex fiber pattern that is impossible to duplicate precisely, as its broad femoral footprint causes wider variation of fiber tension during knee motion than that of the ACL. Successful PCL reconstruction is technically more difficult than ACL reconstruction. Some surgeons prefer special PCL braces to force the tibia anteriorly, but we have not found them to be necessary. In addition, patients with chronic PCL deficiency who have severe muscle atrophy, loss of knee motion, or hyperextension gait abnormalities require extensive rehabilitation and gait retraining (see Chapter 34, Correction of Hyperextension Gait Abnormalities: Preoperative and Postoperative Techniques) before reconstruction.107. Contraindications to PCL reconstruction include acute partial and complete isolated tears that will heal and provide partial function with conservative treatment. In addition, two-bundle techniques may afford improved stability in both flexion and extension when compared to single-bundle reconstructions.2,3 To date, however, there is no consensus regarding the superiority of one technique over another. Joints are named for the two bones that articulate with each other. The primary goal of this protocol is to protect the reconstruction while steadily progressing towards and ultimately achieving pre-injury level of activity. The PCL attaches to the posterior intercondylar area and passes anterosuperiorly to insert into the lateral surface of the medial femoral condyle.. A tourniquet is applied to the operative extremity, and the surgical leg is prepped and draped in a sterile fashion. A trial of function is encouraged in which the patient is monitored for overuse symptoms or giving-way episodes. As previously discussed, associated injuries are very common with PCL injury, and if unrecognized will result in increased in situ forces on the PCL graft and almost certain graft attrition and failure.34 The most common associated injury resulting in PCL graft failure is the missed PLC injury.2,38 This includes PCL injuries with combined LCL and popliteus/popliteal fibular ligament injuries, and just as important are popliteus/popliteal fibular ligament injuries with an intact LCL. The operation can be lengthier than other more common surgical procedures, and thus certain precautions need to be taken. Choice of autograft versus allograft has not been proven to play a significant role in outcome.16 Theoretically, use of a transtibial approach may decrease accuracy of tunnel placement, and the acute posterior turn of the graft may lead to tunnel erosion, higher graft stresses, and graft elongation. Posterior cruciate ligament (PCL) reconstruction. Ensure wound healing 3. Replacement of the Torn Posterior Cruciate Ligament with a Mid-Third Patellar Tendon Graft with Use of a Modified Tibial Inlay Method. Upon successful return to activity, the patient is encouraged to continue with a maintenance program. Some authors believe that tibial inlay techniques allow greater initial stability due to avoidance of the killer turn, and, indeed, some recent evidence indicates that tibial inlay techniques may result in less graft laxity. The Achilles tendon reconstruction was used with both an isometric and a nonisometric femoral site, allowing us to confirm the results with the wire cable. Several reconstructive techniques exist to treat posterior cruciate ligament (PCL) deficiency. Partial weight bearing as tolerated and quadriceps exercises start on the first postoperative day. Based on advanced anatomy and biomechanics, new surgical techniques have been developed to restore native knee kinematics and to control Dislocated knees require initial observation, vascular evaluation (ankle/brachial index), possible arteriography, early protected range of motion, and rehabilitation to restore muscle function before PCL reconstruction. One should note the importance of the vertical orientation and proximity to the medial femoral condyle articular carti-lage margin. Most knees with grade III laxity before surgery are reduced to grade I, and nearly all are reduced to at least grade II.4–6 In addition, statistically significant improvements in posterior tibial displacement on stress radiographs and KT-1000 testing have been documented after multiple reconstructive techniques.10. Frank R. Noyes, ... Timothy P. Heckmann, in Noyes' Knee Disorders: Surgery, Rehabilitation, Clinical Outcomes (Second Edition), 2017. With identification of the PCL reconstruction that most accurately restores knee kinematics and joint contact pressures, one might expect to demonstrate decreases in late-onset arthritis (Box 53-5). Maintain your operative dressing, loosen bandage if swelling of the foot or … L. Joseph Rubino MD, Mark D. Miller MD, in Surgical Techniques of the Shoulder, Elbow, and Knee in Sports Medicine, 2008. Residual laxity after PCL reconstruction is the most common complication, and can have multiple causes. In this technique, PCL is reconstructed through 3 anterior portals: anterolateral portal, anteromedial portal, and inferior anterolateral portal, whereas the PCL remnant is preserved with great possibility. Background: Posterior cruciate ligament (PCL) reconstruction is commonly performed to restore joint stability and prevent posterior tibial translation at higher flexion angles. PCL injury usually occurs with sudden, direct impact, such as in a car accident or during a football tackle. The PCL is intracapsular but extrasynovial … Rehabilitation after PCL reconstruction should focus on resolving impairments and lessening functional limitations and disability. Teresa E. Doerre, ... Christopher D. Harner, in Complications in Orthopaedics: Sports Medicine, 2019. When the knee is in extension, it makes an almost 90º turn as it passes anterosuperiorly. If you are experiencing pain in the ligament behind the knee, you may be a candidate for PCL knee surgery. PCL reconstruction is surgery to rebuild a torn posterior cruciate ligament (PCL) in the knee. Combined Posterior Cruciate Ligament and Superficial Medial Collateral Ligament Knee Reconstruction: Avoiding Tunnel Convergence Editorial Commentary: Arthroscopic Outcomes Are Equal to Open Popliteus Tendon Reconstructions, but Do Not Forget That the Goal Is a Stable Posterior Cruciate Ligament Reconstruction As previously discussed, athletes who wish to resume high-risk sports that involve jumping, cutting, and pivoting are encouraged to complete a course of Sportsmetrics training to reduce the risk of a reinjury before returning to these activities. The goal of rehabilitation is to achieve adequate knee stability, full range of motion, and quadriceps strength that is symmetrical to that of the contralateral leg. However, the PCL injury usually occurs with sudden, direct impact, such as in a car accident or during a football tackle. Rehabilitation should be directed at resolving these impairments. Finally, patients may continue to have postoperative laxity in the knee by instrumented and objective testing measures. Chapter 23 Rehabilitation of Posterior Cruciate Ligament and Posterolateral Reconstructive Procedures Frank R. Noyes, MD, Sue D. Barber-Westin, BS, Timothy P. Heckmann, PT, ATC CLINICAL CONCEPTS 631 PCL CLINICAL BIOMECHANICS 632 PROTOCOL FOR PARTIAL OR ACUTE ISOLATED PCL RUPTURES 634 PCL RECONSTRUCTION … It is important to distinguish joint instability symptoms from symptomatic arthritis, in which a ligament reconstruction would provide little to no benefit. WOUND CARE. Overall, good to excellent results can be expected regardless of the specific operative technique used, with normal or near-normal posterior drawer test results found in more than 95% of postoperative patients. Posterior cruciate ligament (PCL) ligament reconstruction – the ligament, located in the centre of the knee that controls the backward movement of the tibia it is also a common knee ligament to be injured. However, persistent knee laxity after reconstruction is often reported. Posterior Cruciate Ligament Reconstruction Surgical Technique The patient is positioned on the operating table in the supine position, and the surgical and nonsurgical knees are examined under general or regional anesthesia. Posterior cruciate ligament (PCL) injuries can be debilitating knee injuries, having involvement in up to 44% of traumatic knee injuries. endstream endobj 308 0 obj <>stream During the in-season, a conditioning program of two workouts a week is recommended. The patient is allowed to return to full activities 9 to 12 months after surgery, depending on the individual demands of daily activity and the progression of physical therapy. Early activity following PCL repair can lead to increased laxity. Keywords Posterior cruciate ligament Reconstruction Retrospinal Systematic review Tibial tunnel placement Introduction Posterior cruciate ligament (PCL) surgery has evolved significantly in recent years. You can injure your posterior cruciate ligament if your knee sustains a head-on blow (for example in a motorbike accident or a rugby injury). In addition, PCL reconstruction is more commonly performed in the setting of combined ligamentous injuries. We prefer bracing in full extension for the first 4 weeks postoperatively. This is the joint that is primarily responsible Maintain full knee extension (straighten knee fully) 4. ScienceDirect ® is a registered trademark of Elsevier B.V.
