Description
Knee Surgery refers to a variety of surgical procedures performed to treat injuries, arthritis, deformities, and other conditions affecting the knee joint. The type of surgery depends on the specific problem, severity, and patient factors like age, activity level, and overall health.
🦵 Types of Knee Surgery
1. Arthroscopic Knee Surgery (Minimally Invasive)
Used for:
Meniscus tears
ACL or PCL injuries
Loose bodies
Cartilage damage
Synovial inflammation
Recovery: 2–6 weeks depending on procedure
2. Meniscus Surgery
Options:
Meniscectomy (removal of torn part)
Meniscus repair (suturing the tear)
Recovery: Meniscectomy: 2–4 weeks; Repair: 3–4 months
3. ACL Reconstruction
Used for: Torn anterior cruciate ligament (common in athletes)
Graft options: Hamstring, patellar tendon, or donor tissue
Recovery: 6–9 months with physical therapy
4. Total Knee Replacement (TKR)
Used for: Severe arthritis or knee joint damage
Replaces: Entire joint with metal and plastic components
Recovery: 3–6 months (may take up to 12 months for full strength)
5. Partial Knee Replacement
Used for: Arthritis in only one compartment of the knee
Less invasive than TKR
Recovery: 1–3 months
6. Osteotomy
Used for: Realigns the knee by cutting and repositioning bone
Good for: Younger patients with early arthritis on one side
Goal: Delay or prevent total knee replacement
7. Cartilage Restoration Surgery
Types: Microfracture, autologous chondrocyte implantation (ACI), osteochondral grafts
Used in: Younger patients with isolated cartilage defects
✅ Common Reasons for Knee Surgery
Torn ligaments (ACL, PCL, MCL)
Meniscal tears
Knee arthritis (osteoarthritis, rheumatoid)
Patellar instability
Fractures
Cartilage loss or damage
Knee deformities (bow-legged or knock-kneed)
⏱️ Typical Recovery Timeline (By Procedure)
Surgery Type Return to Daily Activities Full Recovery
Arthroscopy 1–3 weeks 4–6 weeks
ACL Reconstruction 1–2 months 6–9 months
Meniscus Repair 4–6 weeks (non-weightbearing) 3–4 months
Total Knee Replacement 4–6 weeks 3–6 months
Partial Knee Replacement 2–3 weeks 1–3 months
Osteotomy 2–3 months 6–12 months
⚠️ Risks of Knee Surgery
Infection
Blood clots (DVT/PE)
Nerve or blood vessel injury
Stiffness or limited mobility
Implant wear or failure (in replacements)
Need for revision surgery
🧑⚕️ Aftercare & Rehab
Physical therapy: Crucial for regaining motion and strength
Pain management: Medications, ice, and rest
Mobility aids: Crutches, walker, or brace as needed
Gradual return to activities: Avoid impact sports until cleared
🩻 Imaging & Diagnosis Before Surgery
X-rays: For arthritis, deformity, or fractures
MRI: Best for soft tissue injuries (ligaments, meniscus, cartilage)
CT scan or bone scan: Sometimes used in complex cases
