I now have comprehensive data from textbooks, multiple high-quality RCTs, systematic reviews, and the 2024 ESSKA-AOSSM-AASPT consensus. Let me compile a thorough, well-structured answer.

Evidence-Based Physiotherapy Management of Meniscal Injury

1. Anatomy and Injury Overview

The menisci are C-shaped fibrocartilage structures that increase load-sharing surface area, absorb ~30-70% of compressive loads, and stabilize the knee. The medial meniscus is less mobile (anchored firmly to the MCL and capsule) and is injured far more often than the lateral. Load transfer, shock absorption, joint proprioception, and lubrication are all meniscal functions that are compromised after a tear.

Tear Classification (relevant to physiotherapy decision-making):

Type	Mechanism	Key Features
Vertical/longitudinal	Acute rotational trauma	Young, active patients
Bucket-handle	Acute, high-energy	Mechanical locking, displaced fragment
Horizontal	Degenerative	Middle-aged/older, often asymptomatic
Radial	Acute or degenerative	Risk of meniscus extrusion
Root tear	Axial load	High OA progression risk

Gray's Anatomy for Students, p. 712

2. Clinical Assessment and Diagnosis

History: Joint line pain (medial > lateral), delayed swelling, locking/clicking, giving way, inability to fully extend the knee.

Special Tests:

McMurray's test - valgus/varus + rotation; positive click = meniscal tear
Apley's test - prone compression + rotation
Joint line palpation - most sensitive single test
Thessaly test - 20° flexion weight-bearing rotation (high sensitivity for medial tears)

Imaging: MRI is the gold standard - identifies tear pattern, associated ligamentous/chondral damage, and guides surgical vs. non-surgical decisions. Swanson's Family Medicine Review, p. 846

3. Decision Framework: Surgery vs. Conservative Physiotherapy

This is the most critical and evidence-rich area.

Degenerative Meniscal Tears (Middle-Aged / Older Adults)

Multiple high-quality trials now firmly establish exercise-based physiotherapy as first-line treatment equal or superior to arthroscopic partial meniscectomy (APM):

ESCAPE Trial (5-year follow-up, JAMA Network Open 2022, [PMID 35802374]):

321 patients aged 45-70 with degenerative meniscal tears
16 sessions of exercise-based physiotherapy vs. APM
At 5 years: physiotherapy was non-inferior to surgery (mean improvement 25.1 vs. 29.6 IKDC points; difference 3.5 points, well within the 11-point non-inferiority threshold)
Comparable rates of OA progression in both groups
Conclusion: Exercise-based physiotherapy should be the preferred treatment

OMEX Trial (10-year follow-up, Br J Sports Med 2025, [PMID 39326908]):

140 participants with degenerative meniscal tears
At 10 years: no difference in radiographic OA progression (OARSI sum score difference 0.39; 95% CI -0.19 to 0.97)
Both groups improved in patient-reported pain and function
OA incidence: 23% APM vs. 20% exercise therapy group - not significantly different

2024 Systematic Review of Systematic Reviews (Musculoskeletal Surgery 2023, [PMID 36057031]):

13 systematic reviews analyzed
Unanimous finding: arthroscopic surgery provides no long-term improvement in pain and function over exercise therapy or placebo in middle-aged patients with degenerative tears
Conservative physiotherapy recommended as first-line; surgery reserved for failure of conservative management

Young Adults with Traumatic Tears

DREAM Trial (NEJM Evidence 2022, [PMID 38319181]):

121 young adults (mean age 29.7 years) with MRI-verified tears eligible for surgery
Early surgery vs. 12-week supervised exercise + education (with option for later surgery)
At 12 months: no statistically significant difference in KOOS4 scores (19.2 vs. 16.4 points improvement)
26% from the exercise group eventually crossed over to surgery - i.e., 74% avoided surgery
Both groups had clinically relevant improvements

TeMPO Trial (NEJM 2025, [PMID 41160820]):

879 participants with degenerative meniscal tear and knee pain
Compared home exercise alone vs. home exercise + text reminders vs. home exercise + sham therapy vs. home exercise + standard physiotherapy
Addition of formal physiotherapy was not significantly superior to structured home exercise alone (2.5-point KOOS difference; 98.3% CI -1.3 to 6.2)
Key take-away: a well-structured home exercise programme may be sufficient for many patients

4. Physiotherapy Management Protocol

Phase 1: Acute/Protective Phase (Days 0-2 Weeks)

Goals: Pain and effusion control, protect the meniscus, maintain range of motion (ROM), prevent muscle inhibition

Interventions:

RICE - Rest (protected weight-bearing as tolerated), Ice (15-20 min/hour while awake, never >20 min), Compression (elastic bandage), Elevation
Cryotherapy - reduces swelling and pain
Neuromuscular electrical stimulation (NMES) - combats quadriceps inhibition from effusion
Gentle ROM exercises - heel slides, passive knee flexion/extension within pain-free range
Isometric quadriceps sets - reduces atrophy without joint loading
Gait training - normalize walking pattern, avoid antalgic gait
Education - explain injury, natural history, and set expectations

Precautions: Avoid deep squatting, twisting, and high compressive loads during this phase.

Phase 2: Sub-Acute / Strengthening Phase (2-6 Weeks)

Goals: Restore full ROM, improve quadriceps and hamstring strength, begin functional activities

Key Exercises:

Quadriceps strengthening - mini-squats (0-60° range), leg press, straight leg raises
Hamstring curls - standing or supine
Hip abductor/extensor strengthening - clamshells, side-lying abduction, bridges
Closed-chain exercises - step-ups, lateral step-downs, wall squats
Proprioception/balance training - single-leg standing, wobble board (pain-free only)
Cycling (stationary bike, low resistance) - low-impact ROM + cardiovascular fitness
Aquatic therapy - reduces joint loading while allowing progressive movement

Blood Flow Restriction (BFR) Training: Recommended by the 2024 ESSKA-AOSSM-AASPT Consensus as an adjunct for early-stage strengthening - allows muscle hypertrophy at low loads, minimizing joint stress.

Phase 3: Functional/Neuromuscular Phase (6-12 Weeks)

Goals: Full ROM, strength symmetry, neuromuscular control, functional movement patterns

Interventions:

Progressive loading - deeper squats, lunges, single-leg exercises
Proprioceptive and neuromuscular training - single-leg balance on unstable surfaces, perturbation training
Functional movement patterns - step-downs, lateral movements, low-level plyometrics
Core stability - plank progressions, rotational control exercises
Gait re-education - normalize any compensatory patterns

Phase 4: Return-to-Sport / Activity Phase (12+ Weeks)

Goals: Full return to sport/activity, prevention of re-injury and OA

Per the 2024 ESSKA-AOSSM-AASPT Consensus (Prill et al., Knee Surg Sports Traumatol Arthrosc, 2025), RTS should be criterion-based, not time-based alone.

Return-to-Sport Criteria:

Full ROM restoration
Absence of effusion
Limb symmetry index (LSI) ≥90% on hop tests (single-leg hop, triple hop, crossover hop)
Quadriceps and hamstring strength within 90% of uninvolved limb (isokinetic or handheld dynamometry)
Psychological readiness - patient confidence assessed (e.g., ACL-RSI scale adapted to knee injury)
Sport-specific on-field rehabilitation completed - progressive drills simulating cutting, pivoting, jumping

RTS is NOT recommended when these milestones remain unachieved. Athletes require tailored on-field rehabilitation programs incorporating comprehensive task analysis.

5. Outcome Measures

Recommended patient-reported outcome measures for tracking progress:

Measure	Domain
KOOS (Knee Injury and Osteoarthritis Outcome Score)	Pain, symptoms, function, sport, QoL
IKDC Subjective Knee Form	Knee function
Lysholm Knee Scale	Symptoms and function
VAS / NRS	Pain intensity
Global Rating of Change (GROC)	Patient-perceived improvement
Hop tests (LSI)	Functional performance
Isokinetic / handheld dynamometry	Quadriceps/hamstring strength

6. Post-Surgical Rehabilitation (After Meniscal Repair or Meniscectomy)

For patients who proceed to surgery:

Post-Meniscectomy:

Generally faster recovery (6-8 weeks typical return to sport)
Same phased rehabilitation above, accelerated protocol
Full weight-bearing usually allowed immediately

Post-Meniscal Repair:

Protective weight-bearing for 4-6 weeks (allow repair to heal)
ROM restrictions initially (avoid >90° flexion in some protocols)
Return to cutting/pivoting sports: typically 4-6 months
Emphasis on protecting repair integrity during early phases
European evidence: meniscal repair is preferred over meniscectomy for long-term OA prevention ("Preservation of the meniscus should be the first line of treatment, as partial meniscectomy often leads to worse long-term clinical and radiological outcomes" - ESSKA Meniscus Consensus)

7. Special Considerations

Degenerative/Older Adults: Combine physiotherapy with OA management strategies - GLA:D program (Good Life with osteoArthritis in Denmark) principles apply: strength training + patient education + activity modification.

Mechanical Symptoms (Locking): True mechanical locking from a displaced bucket-handle tear usually warrants urgent surgical referral before or alongside conservative management.

Root Tears: Emerging evidence (Iseki, 2025) shows radial tears carry comparable risk of meniscus extrusion to root tears - careful evaluation and specialist referral advised.

When to Refer for Surgery:

Failure to improve after 3-6 months of supervised physiotherapy
True mechanical locking
Bucket-handle tear with significant displacement
Associated ligamentous instability requiring surgical repair

8. Summary of Evidence Strength

Recommendation	Evidence Level
Exercise therapy = APM for degenerative tears (5-year outcomes)	Level 1 RCT (ESCAPE)
Exercise therapy = APM for degenerative tears (10-year outcomes)	Level 1 RCT (OMEX)
APM provides no long-term benefit over conservative care	Systematic review of 13 SRs
Exercise + education non-inferior to surgery in young adults	Level 1 RCT (DREAM)
Home exercise programme adequate for many patients	Level 1 RCT (TeMPO 2025)
BFR training, NMES as adjuncts	2024 ESSKA-AOSSM-AASPT Consensus
Criterion-based RTS criteria	2024 ESSKA-AOSSM-AASPT Consensus

Bottom line: The evidence base from 2022-2025 is consistent and strong - exercise-based physiotherapy is the first-line management for the majority of meniscal tears, including in young adults. Surgery (repair preferred over meniscectomy) should be reserved for mechanical failure, true locking, or confirmed failure of supervised rehabilitation. Home exercise programmes are effective but should be structured and progressive; formal physiotherapy adds value for complex cases, neuromuscular training, and RTS clearance.
