Meniscus Tear — বাংলায় ক্লিনিক্যাল নোট
Meniscus tear হলো হাঁটুর ভিতরে থাকা C-shaped fibrocartilage — medial meniscus বা lateral meniscus — ছিঁড়ে যাওয়া। Meniscus হাঁটুর shock absorber, joint congruity, load distribution, stability ও proprioception বজায় রাখে। তাই tear হলে pain, swelling, locking/clicking এবং knee instability হতে পারে। Traumatic tear সাধারণত twisting/pivoting injury থেকে হয়, আর degenerative tear বয়স, osteoarthritis ও repetitive microtrauma থেকে ধীরে ধীরে হয়।
1. Definition — সংজ্ঞা
Meniscus tear = হাঁটুর medial বা lateral meniscus-এর partial বা complete rupture/tear, যার ফলে হাঁটুর pain, swelling, mechanical symptoms এবং movement limitation হতে পারে।
Core meaning:
হাঁটুর ভিতরের “cartilage cushion” ছিঁড়ে গেলে সেটাই meniscus tear।
2. Causes / Etiology — কারণগুলো
- Twisting injury / pivoting movement
ফুটবল, ক্রিকেট, basketball, badminton, sudden turn, squatting থেকে হাঁটু rotate হলে meniscus tear হতে পারে। - Deep squat থেকে উঠা
squat অবস্থায় knee flexion + rotation হলে posterior horn medial meniscus বেশি vulnerable। - Sports injury
sudden stop, cutting movement, jump landing, tackle বা direct blow। - ACL injury-এর সাথে meniscus tear
acute ACL tear থাকলে lateral meniscus tear বেশি দেখা যায়; chronic ACL-deficient knee-তে medial meniscus বেশি ক্ষতিগ্রস্ত হতে পারে। - Degenerative meniscal lesion
বয়স বাড়া, osteoarthritis, obesity, varus knee, repetitive microtrauma—এগুলোতে meniscus দুর্বল হয়ে সামান্য movement-এও tear হতে পারে। ESSKA traumatic tear ও degenerative lesion আলাদা করে দেখে, কারণ management ভিন্ন। - Occupational kneeling / heavy work
যারা বারবার kneel/squat করেন, heavy lifting করেন, তাদের risk বেশি। - Previous knee injury or surgery
আগের ligament injury, meniscal repair/meniscectomy, malalignment থাকলে recurrence বা degeneration হতে পারে।
3. Symptoms — লক্ষণগুলো
- Joint-line pain
হাঁটুর ভেতরের পাশে ব্যথা হলে medial meniscus, বাইরের পাশে হলে lateral meniscus suspected। - Swelling / effusion
injury-এর কয়েক ঘণ্টা থেকে ২৪–৪৮ ঘণ্টার মধ্যে swelling হতে পারে; meniscus tear-এ delayed/intermittent swelling common। - Locking
হাঁটু পুরোপুরি সোজা করতে না পারা—especially bucket-handle tear-এ urgent orthopedic review দরকার। - Clicking / popping / catching
হাঁটু বাঁকানো, সিঁড়ি ওঠা, squat করার সময় click/catch অনুভূত হয়। - Giving way / instability feeling
রোগী বলে: “হাঁটু ভেঙে যাচ্ছে/সাপোর্ট দিচ্ছে না।” - Pain with squatting or twisting
নামাজের বসা, squat toilet, নিচু হয়ে কাজ, খেলাধুলায় pain বাড়ে। - Reduced range of motion
flexion/extension painful বা limited হতে পারে। - Recurrent pain after activity
হাঁটা বা খেলাধুলার পরে swelling ও pain ফিরে আসে।
4. Clinically Diagnosis — ক্লিনিক্যাল ডায়াগনোসিস
AAOS 2024 guideline অনুযায়ী joint-line tenderness, McMurray test ও Thessaly test একসাথে করলে acute meniscal tear diagnose করতে clinically helpful; MRI preferred imaging modality।
History
- Injury mechanism: twisting, pivoting, squatting, sports trauma
- Pain site: medial/lateral joint line
- Swelling timing: immediate হলে ACL/fracture ভাবতে হবে; delayed হলে meniscus বেশি likely
- Mechanical symptoms: locking, catching, clicking
- Functional limitation: stairs, squat, walking, sports
- Previous knee injury/OA history
Physical examination
- Joint line tenderness
সবচেয়ে sensitive clinical signগুলোর একটি; medial/lateral joint line palpation করলে pain। - McMurray test
Knee flexion → tibial rotation → extension; pain/click হলে positive। medial meniscus test করতে tibia externally rotate করা হয়। - Thessaly test at 20° knee flexion
রোগী affected leg-এ দাঁড়িয়ে body rotate করবে; pain/click/locking হলে positive। - Apley compression test
Prone position, knee 90° flexion, tibial compression + rotation; pain হলে meniscal pathology suspect। - Effusion test
Patellar tap / bulge sign। - ROM test
Full extension block থাকলে displaced bucket-handle tear suspect। - Ligament test must be done
Lachman, anterior drawer, pivot shift — ACL associated injury exclude করার জন্য।
5. Investigations — নির্দিষ্টভাবে কী কী করবেন
- X-ray knee — AP, lateral, skyline/merchant, weight-bearing view
Meniscus directly দেখা যায় না; fracture, osteoarthritis, loose body, chondrocalcinosis exclude করার জন্য। Young acute meniscal injury-তে X-ray normal থাকতে পারে। - MRI knee without contrast — best imaging
Meniscus tear, ACL/PCL injury, cartilage injury, bone bruise, root tear, bucket-handle tear দেখতে best। AAOS guideline MRI-কে preferred imaging modality বলেছে; CT arthrography/US MRI unavailable বা contraindicated হলে বিকল্প। - MRI findings
Grade III signal extending to superior/inferior articular surface = tear; bucket-handle tear-এ double PCL sign; root tear-এ meniscal extrusion/ghost sign দেখা যেতে পারে। - Ultrasound
Effusion, parameniscal cyst দেখতে সাহায্য করতে পারে; meniscal tear diagnosis-এর জন্য MRI-এর substitute নয়, তবে MRI contraindicated হলে adjunct। - Diagnostic arthroscopy
Purely diagnostic হিসেবে এখন কম করা হয়; usually therapeutic arthroscopy—repair/partial meniscectomy করতে হলে। - Lab test
Routine দরকার নেই। Fever, hot swollen knee, severe inflammatory picture থাকলে CBC, ESR/CRP, serum uric acid, joint aspiration for Gram stain/culture/crystal analysis করা উচিত।
6. Differential Diagnosis — কোন রোগগুলো exclude করবেন
- ACL tear
- MCL/LCL sprain
- Osteoarthritis flare
- Patellofemoral pain syndrome
- Plica syndrome
- Osteochondral lesion / loose body
- Tibial plateau fracture
- Septic arthritis
- Gout / pseudogout
- Pes anserine bursitis
7. Complications — জটিলতা
- Chronic pain and recurrent swelling
Tear untreated থাকলে knee effusion বারবার হতে পারে। - Mechanical locking
Displaced bucket-handle tear knee extension block করতে পারে। - Quadriceps wasting
pain ও disuse-এর কারণে thigh muscle দুর্বল হয়। - Cartilage damage
torn fragment joint surface ঘষে cartilage injury করতে পারে। - Early osteoarthritis
Meniscal tear ও meniscectomy—দুটিই knee joint degeneration/OA risk বাড়াতে পারে; তাই surgery করলে যতটা সম্ভব meniscus preserve করা guideline-based। - Meniscal cyst
Horizontal tear-এর সাথে parameniscal cyst হতে পারে। - Reduced sports/work performance
pivoting, kneeling, squatting, long walking সীমিত হয়।
8. Treatment / Management
A. Non-pharmacological management
- Acute phase: PRICE
Protection, Rest, Ice 15–20 min, Compression bandage, Elevation — প্রথম 48–72 ঘণ্টা। - Activity modification
squat, kneeling, running, pivoting, jump landing বন্ধ। - Physiotherapy
quadriceps strengthening, hamstring strengthening, hip abductor strengthening, ROM exercise, proprioception/balance training। - Brace / crutch
painful walking হলে short-term crutch; locking থাকলে urgent ortho referral। - Weight reduction
degenerative meniscal lesion/OA থাকলে weight control pain কমায়। - Surgery
Traumatic repairable tear-এ meniscus repair preferred, কারণ preservation করলে long-term OA risk কমতে পারে। Partial meniscectomy শুধু irreparable complex/degenerative/flap/non-reducible bucket-handle tear-এ বিবেচনা। - Degenerative meniscal tear
Exercise-based rehab first-line; degenerative knee disease/meniscal tear-এ arthroscopic surgery প্রায় সব রোগীর জন্য routine recommended নয়—BMJ guideline strong recommendation against arthroscopy দিয়েছে।

- Mild pain, no major swelling
- Paracetamol 500 mg–1 g PRN
- Topical diclofenac gel
- PRICE + physiotherapy
কেন: pain control, systemic NSAID avoid করা যায়।
- Moderate inflammatory knee pain/swelling
- One NSAID only: Ibuprofen / Naproxen / Aceclofenac / Diclofenac / Etoricoxib
- Add PPI if GI risk or NSAID course needed
কেন: prostaglandin-mediated inflammation ও pain কমে; rehab easier হয়।
- Severe acute pain / post-trauma pain
- Paracetamol + short course NSAID
- Rescue: Tramadol short-term or Ketorolac only selected severe cases
কেন: severe pain control; তবে dependency/GI-renal risk থাকায় short-term।
- Degenerative meniscal lesion + OA flare/effusion
- Paracetamol/topical NSAID ± short oral NSAID
- Physiotherapy + weight reduction
- Selected case: intra-articular steroid by specialist
কেন: OA/synovitis-driven pain control; meniscus healing নয়।
- Locked knee / bucket-handle tear / displaced tear
- Analgesia only temporary
- Urgent orthopedic referral for arthroscopic repair/management
কেন: mechanical block medicine দিয়ে ঠিক হয় না।
11. Prevention — কীভাবে প্রতিরোধ করবেন
- Exercise-এর আগে warm-up এবং dynamic stretching।
- Quadriceps, hamstring, gluteus medius strengthening।
- Sudden twisting/pivoting কমানো; sports technique ঠিক করা।
- Squat করলে knee alignment ঠিক রাখা—knee যেন ভিতরে collapse না করে।
- Obesity থাকলে weight reduction।
- Proper footwear; uneven ground এ running avoid।
- ACL injury থাকলে যথাযথ rehab/brace/surgery plan।
- Heavy occupational kneeling করলে knee pad ব্যবহার।
- Previous meniscus injury থাকলে return-to-sport ধীরে ধীরে, physiotherapist clearance নিয়ে।
- Degenerative knee pain থাকলে repeated deep squat, squat toilet, heavy stair climbing কমানো।
12. Overview / Summary
Meniscus tear হলো হাঁটুর fibrocartilage cushion-এর rupture। প্রধান লক্ষণ হলো joint-line pain, swelling, locking/catching, clicking এবং squat/stairs-এ pain। Clinical diagnosis history + joint-line tenderness + McMurray/Thessaly/Apley test দিয়ে করা হয়; MRI হলো preferred investigation। Treatment-এর মূল হলো PRICE, physiotherapy, activity modification, pain control; traumatic repairable tear-এ meniscus preservation/repair preferred, আর degenerative tear-এ conservative rehab first-line।
13. Actionable Plan / Steps
- Acute injury হলে: 48–72 ঘণ্টা PRICE, weight-bearing কমানো, painful squat/twist বন্ধ।
- Clinical exam করুন: joint line tenderness, McMurray, Thessaly, effusion, ROM, ACL/MCL testing।
- X-ray করুন: fracture/OA/loose body exclude করতে।
- MRI করুন: locking, persistent swelling/pain, sports injury, suspected ACL/root/bucket-handle tear, surgery planning থাকলে।
- Medicine: paracetamol ± one NSAID ± PPI; two NSAID একসাথে নয়।
- Physiotherapy: ROM → quadriceps/hamstring strengthening → proprioception → sport-specific training।
- Urgent ortho referral: locked knee, extension block, severe swelling, suspected bucket-handle/root tear, ACL-associated injury, failed conservative treatment 4–6 weeks।
