3/6/2017 Objectives • Understand basic healing times and to be able to The Complex Cases- Rehabilitation prioritize pathology within rehabilitation of Multi-Ligament Knee continuum. • Gain knowledge of precautions and biomechanics Reconstruction & Meniscus behind specific tissue restrictions and function with rehab tasks. Pathology • Utilize rehabilitation principles incorporating criteria based rehabilitation competently and Tyler Opitz, DPT, SCS appropriately. March 3 rd , 2017 • Discuss patient outcomes, expectations, and determine return to play/sport criteria Multi-Ligament Knee Injury • Defined as injury to 2 or more of the 4 major ligaments in the knee (Dywer et al., 2012) • Multi-ligament knee injuries are often associated with knee dislocations – Knee dislocation 0.02% of all orthopaedic injuries (Skendzel et al., 2012) – Invariably results in 3 of 4 knee ligament injury (Fanelli et al., 2005) • 11% of all ligamentous injuries (Bispo et al., 2008) • 98.2% males (Bispo et al., 2008) Knee Dislocation classification Knee Anatomy Factors Classifications 5 Categroies of dislocation- Direction • KD-I- Single cruciate torn • oriented: (ACL or PCL) Anterior – Posterior – • KD-II- Bicruciate disruption, Lateral – Medial MCL/LCL intact – Rotatory- Anterior-medial & -Lateral, – Posterior-medial & lateral • KD-III- Bicruciate disruption, Open vs closed • torn MCL or LCL/PLC High energy vs low energy • Dislocated vs subluxed • KD-IV- ACL, PCL, MCL, LCL • Complete dislocation may spontaneously – torn reduce Any triligamentous injury constitutes – • KD-V- All ligaments torn dislocation Neurovascular involvement with fracture • Fanelli et al., 2005 – 1

(Mills et al., 2004) – Popliteal injury 4.8%- 65% of time • High energy injuries increased incidence – Fibular nerve injury 20% of time (Robertson et al., 2006) Complications Regional Interdependence • Concept of Regional • New definition: • DVT Interdependence is the • Does not limit to • Compartment syndrome relationship of adjacent musculoskeletal system and distant segments – “the concept that a have on motion and patient’s primary stability of body parts of musculoskeletal seemingly unrelated symptom(s) may be directly or indirectly sections that can related or influenced by contribute to pathology impairments from various or have an effect on one body regions and another. (Wannier et al., 2007) systems regardless of proximity to the primary symptom(s).” (Sueki et al., 2013) 2

Involved structures- Ligaments, Menisci, nerve, vascular supply 2. Comorbidities with injury (compartment syndrome) 3. Pain level 4. Duration since injury 5. Tissue healing & quality 6. Patient stage of rehab 7. Current level of function and movement quality 8. Patient Goals 9. Outcomes expectations 10.

Functional tasks are a byproduct of doing basic movement • patterns properly, NOT a product of TIME !!! Grzybowski et al., 2015, Wahoff et al., 2014 Knee Symmetry Model Rehab Concepts • Increasing depth of squat increases SHEAR forces on • Goal is to restore limb symmetry between limbs knee joint • Utilizes subjective and objective measures to • Increased knee extension in closed chain increases determine when successful rehab has concluded. COMPRESSIVE loads on knee joint. (Biggs et al., 2009, Kinzer et al., 2010) • Protect lateral meniscus as has increased translation – Measures Include: with knee motion than medial meniscus • ROM • Bone tunneling has increased risk for stress fractures • Strength compared to healing of traditional fractures • Stability • Avoid loading maturing reconstructed ligaments even • Girth though patient function is improving. • Subjective questionnaire scores 3
