Here is a clear breakdown of what the MRI shows and what to do next.
MRI Left Knee Summary — 3 Key Findings
Finding 1: ACL Sprain (No Tear)
The ACL shows diffuse signal change (edema/inflammation within the fibers) but no structural tear. This is consistent with a Grade I–II ACL sprain.
Finding 2: Near Full-Thickness Articular Cartilage Loss — Patella (Medial & Lateral Facets)
This is significant. The patellar cartilage is almost completely worn away at both facets, with underlying subcortical cysts and bone marrow edema — indicating advanced patellofemoral chondral damage (Grade III–IV equivalent on Outerbridge scale).
Finding 3: Lateral Tibial Condyle Bone Marrow Edema — Bony Contusion
Likely from a recent impact or twisting injury. Will heal with time and activity modification.
What To Do Next — Step by Step
Immediate (Now)
| Action | Reason |
|---|---|
| Rest the knee — avoid deep squatting, stairs, running | Protects the damaged patellar cartilage and allows ACL edema to settle |
| Ice application 15–20 min, 3–4x/day | Reduces bone marrow edema and pain |
| Compression bandage / knee brace | Supports the ACL and reduces swelling |
| Elevate the leg when resting | Reduces inflammation |
| NSAIDs (e.g., Tab. Etoricoxib 60mg or Tab. Ibuprofen 400mg after food, as advised by your doctor) | Pain and inflammation control |
Consult — Within 1 Week
See an Orthopedic Surgeon (preferably a Sports Medicine / Knee Specialist) with this MRI report. This is important because:
- The cartilage loss at the patella is severe (near full thickness) and requires specialist evaluation. This is not something that heals on its own — the surgeon needs to assess whether you need:
- Viscosupplementation injections (hyaluronic acid into the joint)
- Platelet-Rich Plasma (PRP) injection
- Cartilage repair procedures (in younger patients)
- Or long-term management plan if age-related
- The ACL sprain needs clinical examination (Lachman test, anterior drawer test) to confirm stability. According to Bailey & Love's Surgery (p. 585), isolated ACL injuries are initially managed conservatively with bracing + physiotherapy, but surgical reconstruction is considered if instability persists.
Physiotherapy — Start Within 1–2 Weeks
A structured physiotherapy program is essential:
- Quadriceps strengthening (especially VMO — vastus medialis oblique) to offload the patellofemoral joint
- Straight leg raises, terminal knee extensions
- Avoid deep knee bends, high-impact activities
- Patellar taping or brace — shown in controlled trials (Harrison's, p. 10420) to reduce patellofemoral pain by improving patellar tracking
- ACL rehabilitation exercises to restore stability and proprioception
Do NOT Do
- Do not ignore the cartilage finding — it is the most serious finding here
- Do not return to running, sports, or heavy physical work until cleared by a specialist
- Do not take steroids on your own
Summary Priority List
- See an orthopedic/sports medicine specialist — within 1 week (bring MRI films/CD + report)
- Start conservative measures immediately (rest, ice, brace, anti-inflammatory medication)
- Begin physiotherapy once acute pain settles (within 1–2 weeks)
- Follow-up MRI in 6–8 weeks may be requested by the surgeon to reassess the ACL and bone edema

Based on the three MRI findings — ACL sprain, near full-thickness patellar cartilage loss, and lateral tibial bone contusion — here is the complete physiotherapy (PT) management protocol organized by phase.
Physiotherapy Management — Left Knee
Conditions Being Addressed
- ACL Sprain (intact, no tear — Grade I–II)
- Patellofemoral Chondral Damage (near full-thickness cartilage loss, medial & lateral patellar facets)
- Lateral Tibial Condyle Bone Contusion
Phase 1 — Acute / Protection Phase (Week 1–2)
Goals: Control pain and swelling, protect healing tissues, prevent muscle wasting
| Modality / Exercise | Details |
|---|---|
| RICE Protocol | Rest, Ice (15–20 min, 3–4x/day), Compression bandage, Elevation |
| Transcutaneous Electrical Nerve Stimulation (TENS) | For pain relief — 80–100 Hz, 20–30 min/session |
| Ultrasound Therapy | Pulsed mode (1:4 duty cycle) over lateral tibial condyle and patellar region — promotes bone contusion healing and reduces inflammation |
| Knee brace / patellar stabilizing brace | Worn during activity to offload patellofemoral joint and provide ACL proprioceptive support |
| Ankle pumps | Active dorsiflexion/plantarflexion — prevents DVT, maintains circulation |
| Static Quadriceps contractions (Quad sets) | Patient lies flat, tightens quad without moving knee — hold 5 sec × 10 reps × 3 sets |
| Straight Leg Raises (SLR) | Supine, leg raised to 45°, held 5 sec — prevents VMO atrophy |
| Patellar Taping (McConnell Technique) | Medial glide taping to correct lateral patellar maltracking — reduces patellofemoral pain |
Avoid: Deep squatting, stairs, resisted knee flexion beyond 90°, running
Phase 2 — Subacute / Strengthening Phase (Week 3–6)
Goals: Restore full ROM, strengthen VMO and surrounding muscles, improve neuromuscular control
Range of Motion
- Passive/Active-Assisted Knee Flexion/Extension — progress to full ROM (0–135°)
- Heel slides in supine — controlled ROM without loading cartilage
- Stationary cycling (low resistance, seat raised high) — low patellofemoral joint stress
VMO & Quadriceps Strengthening (critical for patellar cartilage protection)
Bailey & Love's (p. 644) specifically emphasizes VMO development to counteract patellofemoral maltracking and prevent wasting.
| Exercise | Sets × Reps |
|---|---|
| Terminal Knee Extensions (TKE) with resistance band | 3 × 15 — strengthens VMO in terminal range |
| Short Arc Quads (0–30° extension only) | 3 × 15 — safe range for damaged patellar cartilage |
| Wall slides / Mini squats (0–45° only) | 3 × 15 — avoid >45° to reduce patellofemoral stress |
| Step-ups (low step, 10 cm) | 3 × 10 each leg |
| Leg press (low resistance, 0–60° only) | 3 × 15 |
Hamstring & Hip Strengthening (for ACL protection)
| Exercise | Sets × Reps |
|---|---|
| Prone hamstring curls | 3 × 15 |
| Hip abduction in side-lying | 3 × 15 (strengthens glutes, reduces valgus stress on knee) |
| Bridges (Glute bridges) | 3 × 15 |
| Clamshells with resistance band | 3 × 15 |
Electrotherapy (continued)
- NMES (Neuromuscular Electrical Stimulation) over VMO — augments voluntary contraction, reduces atrophy
- IFT (Interferential Therapy) at 80–120 Hz — deep pain relief and edema reduction
Phase 3 — Functional / Neuromuscular Phase (Week 7–12)
Goals: Restore proprioception, functional strength, prepare for daily activities
| Exercise | Purpose |
|---|---|
| Single-leg balance (eyes open → eyes closed) | Proprioception and ACL neuromuscular re-education |
| Balance board / wobble board training | Dynamic proprioception |
| Lateral band walks | Hip abductor and knee stabilizer activation |
| Partial squats with resistance band (0–60°) | Functional strengthening within safe cartilage range |
| Stair training (step-over-step, supervised) | Functional reintegration |
| Swimming / Hydrotherapy | Low-impact full-ROM exercise — excellent for cartilage nutrition |
| Stationary bike with increased resistance | Cardiovascular fitness + quad endurance |
Key Physiotherapy Principles for This Case
| Principle | Rationale |
|---|---|
| Avoid deep knee flexion (>90°) | Patellofemoral contact pressure peaks at 60–90°; full-thickness cartilage loss means bone-on-bone risk beyond this |
| Patellar taping throughout rehab | Corrects maltracking, reduces pain during exercise |
| VMO strengthening is priority #1 | VMO is the primary dynamic stabilizer of the patella — its weakness is the main driver of patellofemoral pain and cartilage wear |
| No impact loading until Phase 3 | Bone contusion at lateral tibial condyle needs 6–8 weeks to heal |
| ACL proprioceptive drills | Even without a tear, the sprain disrupts proprioceptive nerve endings in the ACL — balance and neuromuscular drills restore this |
Modalities Summary Table
| Modality | Phase | Target |
|---|---|---|
| TENS | 1–2 | Pain |
| Pulsed Ultrasound | 1–2 | Bone contusion, inflammation |
| IFT | 1–3 | Deep pain, edema |
| NMES / EMS | 2–3 | VMO activation, muscle wasting |
| McConnell Patellar Taping | 1–3 | Patellar maltracking |
| Hydrotherapy | 3 | Cartilage nutrition, ROM |
Duration & Follow-up
- Total PT duration: 10–12 weeks minimum
- Re-assess at 6 weeks — check ROM, VMO strength, pain levels
- Orthopedic review at 8–12 weeks — specialist decision on whether viscosupplementation (HA injection), PRP, or further intervention is needed for the cartilage damage
- Return to sport/heavy activity: Only after passing functional strength testing (limb symmetry index >90%)
⚠️ This protocol is a clinical guide. A qualified physiotherapist must individualize exercises based on the patient's age, fitness level, pain tolerance, and clinical examination findings.

Yes — but selectively and carefully. Here is a clear breakdown of what is safe, what to modify, and what to avoid given the three findings.
Can You Give Mobilization? — Clinical Decision
| Finding | Impact on Mobilization Decision |
|---|---|
| ACL Sprain (no tear) | Avoid anterior tibial glide; other directions generally safe |
| Near full-thickness patellar cartilage loss | Patellar mobilization YES — but gentle, no compression |
| Lateral tibial bone contusion | Avoid direct pressure/force over lateral tibial condyle |
✅ Mobilizations You CAN Give
1. Patellar Mobilizations — Recommended
This is actually a priority in this case given the cartilage damage and maltracking.
| Technique | Grade | Direction | Purpose |
|---|---|---|---|
| Medial patellar glide | Grade I–II | Push patella medially | Corrects lateral maltracking, reduces patellofemoral compression |
| Superior patellar glide | Grade I–II | Push patella superiorly | Improves terminal extension ROM |
| Inferior patellar glide | Grade I–II | Push patella inferiorly | Improves knee flexion ROM |
| Patellar tilt (medial tilt) | Grade I | Lift lateral border of patella | Reduces lateral retinacular tightness |
Apply in non-weight-bearing (supine), knee relaxed in slight flexion (10–20°). Keep force gentle — Grade I–II only given the cartilage loss.
2. Tibiofemoral Joint Mobilizations — Selectively Safe
| Technique | Grade | Safe? | Reason |
|---|---|---|---|
| Posterior tibial glide (AP) | I–III | ✅ Yes | Improves flexion ROM; safe for ACL sprain |
| Distraction (long-axis traction) | I–II | ✅ Yes | Reduces compressive load, pain relief — evidence supports this in knee OA/chondral damage |
| Medial/Lateral tibial glide | I–II | ✅ Yes | Joint nutrition, pain relief |
| Anterior tibial glide | ❌ Avoid | ACL is sprained — anterior glide directly stresses the ACL | |
| High-velocity thrust (Grade V) | ❌ Avoid | Contraindicated with bone contusion and cartilage damage |
3. Soft Tissue Mobilization — Recommended
- Quadriceps and ITB soft tissue release — reduces lateral patellar pull
- Retinacular stretching — lateral retinaculum tightness worsens patellar maltracking
- Hamstring / calf massage — reduces posterior tightness that increases patellofemoral load during gait
❌ Mobilizations to AVOID
| Avoid | Why |
|---|---|
| Anterior tibial glide / drawer mobilization | Directly stresses the sprained ACL |
| Grade IV–V (high amplitude/thrust) tibiofemoral | Risk of subchondral damage over bone contusion site |
| Direct pressure over lateral tibial condyle | Active bone marrow edema — painful and counterproductive |
| Full range passive flexion beyond 90° | High patellofemoral compression force on denuded cartilage |
Maitland Grading Guide for This Case
| Grade | Use For |
|---|---|
| Grade I–II | Pain relief, joint nutrition — use during acute/subacute phase NOW |
| Grade III | ROM improvement — safe for posterior glide and patellar glides once pain settles (Week 2–3 onward) |
| Grade IV–V | Avoid in this case |
Evidence Base
According to the Non-Arthroplasty Treatment of Osteoarthritis of the Knee Guidelines, manual therapy combined with exercise produces significantly greater improvements in pain and function at 8–9 weeks compared to exercise alone (Fitzgerald 2016, Deyle 2000). Since this patient has near full-thickness cartilage loss (essentially a chondral OA-equivalent lesion), early manual therapy is clinically supported.
Bottom Line
Yes, mobilization is indicated — start with Grade I–II patellar glides (medial, superior, inferior) and tibiofemoral distraction in the current acute/subacute phase. These reduce pain, improve joint nutrition, and correct patellar maltracking without stressing the sprained ACL or the bone contusion. Progress to Grade III posterior tibial glides for ROM from Week 3 onward. Avoid anterior tibial glide and high-grade thrust techniques throughout.
