Rehabilitation Support Principles

Ordered Scar Tissue Formation
Adjustable support straps limit abnormal shear and rotational forces, ensuring newly formed collagen fibers align along natural stress lines.
Muscle Function Maintenance
Balanced support reduces compensatory movements and prevents disuse atrophy; combined with low-impact exercises to preserve muscle strength.
Bone Remodeling Promotion
Appropriate loading and evenly distributed pressure stimulate normal bone remodeling and prevent osteoporosis.
Cartilage Wear Protection
Restricts excessive impact and friction, maintains a lubricated joint environment, and slows degenerative changes.

Rehabilitation Protocol

Injury Stage	Recovery Period	Weight Management	Exercise Plan	Medications / Supplements	Physical Therapy
Stage I: Mild Injury (< 25% fiber tear)	0–12 weeks	• High‑protein, low‑fat diet • Reduce carbohydrates; include fruits & veggies • Goal: 1–2% body‑weight loss per week	• Weeks 0–2: flat‑ground slow walks, 5–10 min/session, 2×/day • Weeks 3–6: increase to 10–15 min/session • Weeks 7–12: up to 15–20 min/session; add gentle incline walking	• Acute phase NSAIDs (vet‑guided, first 1–2 weeks) • Ongoing: glucosamine + chondroitin, fish oil, vitamin C	• Infrared therapy & warm compresses, 15 min, 2×/day • Gentle massage & passive ROM exercises, 2–3×/day
Stage II: Moderate Injury (25–50% fiber tear)	12–16 weeks	• Continue low‑fat, low‑carb diet • Increase protein (chicken breast, fish) • Maintain calorie control to prevent weight gain	• Weeks 0–4: daily walks, 10–15 min • Weeks 5–8: up to 20 min • Weeks 9–16: introduce light jogs (2–5 min) & gentle hill work	• Continue glucosamine & chondroitin • Adjust anti‑inflammatories as needed • Add green‑lipped mussel extract & vitamin E	• Hydrotherapy (low‑impact water walks), 2–3×/week, 5–10 min • Contrast hot/cold compresses, massage & balance exercises
Stage III: Severe Injury (50–75% fiber tear)	24–36 weeks	• Strict low‑calorie diet • High‑protein foods (beef, lamb, turkey) • Supplement BCAAs & collagen to preserve muscle mass	• Weeks 0–6: daily walks, 10–15 min (low intensity) • Weeks 7–12: 20–30 min walks • Weeks 13–16: short slow jogs (2–5 min) & hill walking • Weeks 17–36: up to 30–40 min walking + low‑intensity running	• Ongoing anti‑inflammatory management • Continue glucosamine & chondroitin • Add calcium & vitamin D • BCAAs (1–1.5 g/kg) to prevent muscle loss	• PT 3×/week: infrared, warm compresses • Low‑frequency electrical stimulation & deep massage • Balance training to enhance stability
Stage IV: Complete Rupture (> 75% fiber tear with meniscus injury & OA)	Lifetime management	• Strict weight control • High‑protein, low‑fat diet • Long‑term Omega‑3, calcium & vitamin D supplementation to prevent osteoporosis	• Early (0–8 weeks): very restricted—short walks only, 2–3 min/session • Mid (9–14 weeks): low‑intensity walks, 10–15 min/session • Late (15 weeks+): only wear brace during long or intense activity; otherwise light daily movement	• Long‑term NSAIDs (vet‑guided) • Ongoing glucosamine, chondroitin, green‑lipped mussel & fish oil • Antioxidants (vitamin E + C) as needed	• Advanced PT: laser therapy, ultrasound • Regular massage • Low‑impact hydrotherapy to boost circulation
