Study Notes
Soft Tissue Healing
- Soft tissue healing is a multi-stage process involves different phases
- The presentation discusses the phases of soft tissue healing: inflammatory, proliferative, and remodeling
- The presentation also covers the various soft tissue lesions and the different grades of sprains and strains
- Healing times vary depending on the tissue and grade: muscles (0-3 days to 3-12 weeks), tendons (3-7 weeks to 3-6 months), ligaments and sprains (2-8 weeks to 6-12 months), meniscus/labrum (3-12 months), and fractures (6-8 weeks)
Objectives
- Students should understand different types of soft tissue lesions
- Students should know the different phases of soft tissue healing, in order to provide appropriate treatment recommendations for each phase
- Students should understand the PEACE acronym for managing soft tissue injuries
- The acronym PEACE stands for Protection, Elevation, Avoid anti-inflammatories, Compression, and Educaiton
Soft Tissue Lesions
- Stain: Damage to the musculotendinous unit
- Sprain: Damage to joint capsule or ligaments
- Dislocation: Complete displacement of a joint
- Subluxation: Partial displacement of a joint
- Tendinopathy: Damage to the tendon caused by repeated mechanical stress
- Synovitis: Inflammation of the synovial membrane
- Hemarthrosis: Bleeding into a joint
- Bursitis: Inflammation of the bursa
- Contusion: Bruising caused by trauma
Grades of Sprain/Strain
- Grade 1: Stretching or microscopic tears; minimal swelling, localized pain, and almost normal range of motion (ROM)
- Grade 2: Partial tear; moderate swelling, bruising, loss of ROM, and significant pain
- Grade 3: Complete tear; severe pain, swelling, bruising, and loss of ROM
Healing Times by Grade
- A chart specifying tissue type, what caused the injury (exercises, tendonitis etc), and how long healing will take for each grade
Soft Tissue Repair
- Inflammatory Phase: Assess the damage, clear damaged tissue, and lasts 4-6 days to 2 weeks
- Proliferative Phase: Begin repairs, limited circulation (4-24 days, up to 6 weeks in e.g. tendons) lasts 3 weeks to 2 years depending on tissue and damage grade.
- Remodeling Phase: Maturation of scar tissue, contracture of scar tissue, remodeling from Type III to Type I collagen, collagen aligns to stress, and no inflammation signs
Stages of Wound Healing
- The presentation includes an image of a graph visually representing different phases of healing: inflammation (4-6 days), proliferation (4-24 days), and remodeling (21 days to 2 years)
Inflammatory Phase
- Tissue response includes chemical signals (e.g., histamine, bradykinin) that induce changes in the blood vessels and create an edema
- Include chemotaxis where immune cells travel to the injury site
- Phagocytosis which involves the removal of tissue debris and pathogens
- Clinical signs may involve redness, swelling, heat, pain, and reduced movement because of pain
Inflammatory Phase Management Considerations
- Control stress to the injured tissue, using i.e. Protection
- Reduce swelling and control inflammation but do not interfere with the natural inflammatory response.
- Pain assessment for treatment plan and guidance
- Use PEACE guidance to provide an outline for managing the injury
PEACE
- Protection – Avoid actions that increase pain
- Elevation – Elevate injured limb above the heart
- Avoid anti-inflammatories– Do not use anti-inflammatories as they impede healing
- Compression – Use elastic wraps or bandages
- Education - Let the body heal itself
Proliferative Phase
- Capillary bed growth, collagen formation (Type III) and granulation tissue formation
- Pain occurs in correlation to tissue resistance as healing progresses.
- Tissue healing proceeds as inflammation reduces.
- LOVE acronym is used to aid in considerations during this phase: Load, Optimism, Vascularisation, Exercise
LOVE
- Load – increase stress to tissues based on pain tolerance guides your gradual return to normal activities
- Optimism – promotes recovery by being confident and positive
- Vascularisation –Choose activities to increase blood flow
- Exercise –Restore mobility, strength, and proprioception
Remodeling Phase
- Maturation of scar tissue, contracture of scar tissue, remodeling of Type III to Type I collagen and the collagen aligning to stress
- No inflammation
- Pain is end-range resistance
- Managing the remodeling phase involves progressive stress/increase in load, intensity and frequency of activities and movements
Factors Affecting Healing
- Lifestyle factors (diet, activity levels, stress, and smoking/alcohol usage)
- Comorbidities (e.g., age, obesity, diabetes, and immunocompromised conditions)
Application
- Cases provided in presentation will involve the use of appropriate phases/grades and recommendations
- Presentation discusses identifying phases of healing for each case.
