Posterior Cruciate Ligament (PCL) Surgery in India and UAE | Complete Patient Guide

• ELIGIBLE CANDIDATES:

• Confirmed Grade III PCL tear (posterior tibial translation >10 mm on stress radiographs or KT-1000/KT-2000 arthrometer testing) with functional instability

• Grade II PCL tear with documented failure of structured conservative management (minimum 3–6 months of quadriceps-focused rehabilitation)

• Multi-ligament knee injury (MLKI) involving the PCL in combination with ACL, posterolateral corner (PLC), or posteromedial corner (PMC) pathology

• Symptomatic PCL-deficient knee in active individuals aged 15–55 years (athletic or high-demand occupational requirements)

• Avulsion fractures of the PCL tibial or femoral footprint amenable to primary repair or reconstruction

• Patients with MRI-confirmed complete PCL rupture (Matava classification Grade III) with associated meniscal or chondral pathology requiring concurrent treatment

• REQUIRED DIAGNOSTIC WORKUP BEFORE TRAVEL:

• MRI of the knee (1.5T or 3T; sagittal and coronal sequences for PCL, posterolateral corner, and cartilage assessment)

• Stress radiographs (posterior tibial translation under 90° flexion; side-to-side difference >10 mm on KT arthrometry confirms Grade III)

• Weight-bearing long-leg alignment radiographs (to rule out concurrent varus/valgus malalignment requiring osteotomy)

• Standing AP, lateral, and Merchant patellofemoral X-rays

• Vascular assessment (ABI/Doppler) if high-energy mechanism or neurovascular symptoms present

• Pre-operative blood panel: CBC, CMP, coagulation profile (PT/INR/aPTT), HbA1c (if diabetic), serology (HIV, HBsAg, HCV) as required by hospital protocol

• ECG and anesthesia fitness evaluation for patients >40 years or with comorbidities

• RELATIVE CONTRAINDICATIONS:

• Severe tricompartmental osteoarthritis (Kellgren-Lawrence Grade III–IV) — consider total knee arthroplasty instead

• Active knee joint infection or systemic sepsis

• Significant ipsilateral vascular injury not yet repaired

• Uncontrolled diabetes (HbA1c >8.5%), poorly controlled coagulopathy, or active anticoagulation that cannot be bridged

• Skeletally immature patients with open physes (require physeal-sparing reconstruction techniques; specialist assessment mandatory)

• Severe ipsilateral quadriceps atrophy or neurological deficit precluding post-operative rehabilitation compliance

GRAFT SELECTION AND TECHNIQUE OPTIONS:

1. ARTHROSCOPIC SINGLE-BUNDLE PCL RECONSTRUCTION (ANTEROLATERAL BUNDLE FOCUS)

The most widely performed technique. A central graft tunnel is drilled at the native PCL femoral footprint on the medial femoral condyle, and the tibial tunnel is placed at the anatomic tibial PCL footprint (approximately 1 cm below the joint line on the posterior tibia). Graft options include:

• Bone-Patellar Tendon-Bone (BPTB) Autograft: Gold standard for high-demand athletes; bone plugs allow robust interference screw fixation and early bone-to-bone healing. Donor site morbidity includes anterior knee pain (up to 15–20%).

• Quadriceps Tendon Autograft (with or without patellar bone plug): Increasingly favored; larger cross-sectional area than hamstring grafts, lower donor site morbidity than BPTB, and biomechanical properties closely matching the native PCL.

• Hamstring Tendon Autograft (4-strand semitendinosus/gracilis): Lower donor site morbidity; commonly used in patients who require preservation of the patellar tendon for prior procedures. Graft diameter target ≥8 mm.

• Achilles Tendon or Tibialis Anterior Allograft: Preferred in revision cases, multi-ligament reconstructions, or when autograft harvest is contraindicated. Eliminates donor site morbidity but carries a small risk of disease transmission and is associated with slower biological incorporation.

2. ARTHROSCOPIC DOUBLE-BUNDLE PCL RECONSTRUCTION

Replicates both the anterolateral (AL) bundle (primary restraint to posterior translation) and the posteromedial (PM) bundle (secondary restraint, load-sharing in near-extension). Two separate femoral and tibial tunnels are drilled. Biomechanical cadaveric studies demonstrate superior restoration of posterior tibial translation and rotational kinematics compared to single-bundle techniques. Technically demanding; best performed by high-volume PCL specialists.

3. TIBIAL INLAY TECHNIQUE

Addresses the 'killer turn' graft angulation inherent to transtibial drilling. A posterior approach (modified posterior approach or posterolateral arthroscopic portal) is used to seat the graft directly into a trough cut at the posterior tibial PCL footprint, eliminating the acute bend the graft must navigate through a transtibial tunnel. Evidence supports lower graft stress and potentially improved long-term outcomes in isolated PCL reconstruction; widely used in the USA and increasingly available at top-tier centers in India and the UAE.

4. MULTI-LIGAMENT KNEE RECONSTRUCTION (MLKI PROTOCOL)

For combined PCL + ACL or PCL + PLC injuries, staged or simultaneous reconstruction is planned based on neurovascular status, soft tissue envelope, and patient physiology. The posterolateral corner (PLC) may require Larson or LaPrade anatomic reconstruction using fibular head-based tunnels. Concurrent meniscal repair, cartilage restoration (microfracture, OATS, or ACI), or high tibial osteotomy (HTO) for varus correction is planned within the same surgical episode when indicated.

5. ROBOTIC-ASSISTED AND COMPUTER-NAVIGATED TECHNIQUES

Selected centers in India (Fortis, Apollo, Kokilaben) and the UAE (Cleveland Clinic Abu Dhabi, Burjeel Medical City) offer computer navigation or robotic assistance (e.g., Stryker Mako, Smith & Nephew CORI) to optimize tunnel placement accuracy within 0.5–1 mm, reducing the risk of tunnel malposition — a primary cause of PCL reconstruction failure. Navigation is particularly valuable in complex multi-ligament and revision cases.

6. PRIMARY REPAIR WITH INTERNAL BRACE AUGMENTATION

For acute avulsion PCL injuries (tibial or femoral bony avulsions), open or arthroscopic primary repair with suture anchor fixation supplemented by synthetic ligament augmentation (InternalBrace, Ligamys) is gaining evidence support, preserving the native PCL's proprioceptive neural elements while protecting the repair during healing. Best results are achieved within 3 weeks of injury.

PRE-OPERATIVE PHASE (Weeks –4 to 0, partially managed remotely with GAF Healthcare coordination):

• Remote consultation: Share MRI, stress X-rays, and clinical history with your assigned GAF Healthcare orthopedic specialist via secure portal. Surgeon confirms operative plan, graft choice, and any concurrent procedures.

• Pre-habilitation (Prehab): 4–6 weeks of targeted quadriceps strengthening, hamstring flexibility, and proprioceptive training to improve pre-operative muscle function and significantly enhance post-operative outcomes. Research demonstrates that prehab reduces post-operative rehabilitation duration by 30–40%.

• Travel planning: GAF Healthcare applies for India e-Medical Visa (processed in 48–72 hours) or UAE entry visa as applicable. Flights and airport transfers are booked.

• Pre-admission (Day –1 to 0): Hospital admission, anesthesia assessment, blood tests, and surgical consent process. Surgeon reviews imaging with patient. Nil by mouth from midnight before surgery.

INTRA-OPERATIVE PHASE (Day 0; Duration: 90–150 minutes depending on technique and concurrent procedures):

• General or spinal anesthesia administered; tourniquet applied for bloodless field.

• Diagnostic arthroscopy performed to confirm PCL pathology, assess menisci, articular cartilage, and all ligamentous structures.

• Graft harvest (if autograft): BPTB, quadriceps tendon, or hamstring graft harvested and prepared on the back table to target dimensions.

• Femoral and tibial tunnel drilling under arthroscopic visualization (navigated or standard, per planned technique).

• Graft passage and tensioning at 70–90° of knee flexion with anterior tibial drawer force applied to reduce posterior sag.

• Fixation with bioabsorbable or titanium interference screws (±cortical button on femoral side for cortical fixation).

• Wound closure, drain insertion (if indicated), and sterile dressing.

• If tibial inlay: posterior mini-open approach precedes the arthroscopic femoral fixation component.

EARLY RECOVERY IN HOSPITAL (Days 1–4):

• Pain management: Multimodal analgesia (NSAIDs, acetaminophen, nerve blocks — adductor canal or posterior capsular block — opioids as rescue only). Minimizes opioid consumption and accelerates mobilization.

• Day 1: Physiotherapist initiates passive range-of-motion exercises (0–90° target), quadriceps setting, and ankle pumps. Patient mobilizes non-weight-bearing (NWB) on crutches.

• DVT prophylaxis: Low-molecular-weight heparin (LMWH) initiated within 12–24 hours post-operatively; compression stockings throughout hospital stay.

• Cryotherapy and limb elevation protocol to manage swelling.

• Day 2–3: Partial weight-bearing (PWB) progressed with physiotherapy supervision; brace locked in full extension for ambulation.

• Discharge Day 3–4: Wound check, drain removal, home physiotherapy protocol and brace instructions issued. Follow-up appointment scheduled.

OUTPATIENT RECOVERY IN DESTINATION COUNTRY (Weeks 1–5 or 6):

• Week 1–2: Continue NWB to PWB progression. Passive ROM to 90°. Wound review and suture/staple removal at Day 10–14.

• Week 3–4: Full weight-bearing achieved. Active-assisted ROM advanced toward 120°. Stationary cycling (no resistance) initiated. Formal physiotherapy sessions 3–5x per week.

• Fit-to-Fly Assessment (Week 4–6): Surgeon evaluates wound healing, DVT risk (clinical assessment ± Doppler if indicated), pain control without systemic medications, and ability to ambulate safely in an airport/aircraft environment. Short-haul flights (≤4 hours) are typically cleared at Week 4–5. Long-haul intercontinental flights require minimum 6–8 weeks post-operatively and mandate LMWH prophylaxis, compression stockings, and in-flight mobility exercises.

HOME REHABILITATION (Months 2–9+):

• Month 2–3: Closed kinetic chain strengthening, proprioception and neuromuscular training, pool physiotherapy.

• Month 3–4: Open kinetic chain exercises introduced cautiously; progressive resistance training.

• Month 4–6: Jogging on flat surface initiated; sport-specific movement patterns begin.

• Month 6–9: Return-to-sport testing (hop tests, isokinetic quadriceps/hamstring strength assessment targeting ≥90% limb symmetry index).

• Month 9–12: Full competitive sport clearance in appropriately tested athletes. PCL graft ligamentization continues through 18 months.
