Treat knee pain with arthroscopic and minimally invasive surgery at Liv Hospital. Our orthopedic surgeons apply advanced methods to restore movement safely and quickly. This gallery reflects not just healing, but the expertise, focus, and precision behind every procedure.
What are the most common types of knee surgeries?
01
The most common procedures include arthroscopic surgery for meniscus repair, ACL reconstruction, total knee replacement, and partial knee replacement. These address different levels of knee damage from injuries to severe arthritis.
Other common surgeries include cartilage restoration procedures, knee osteotomy, and patellar realignment. The choice depends on patient age, activity level, and specific knee problems.
When is knee replacement surgery recommended?
02
Knee replacement is considered when conservative treatments fail to relieve severe arthritis pain. Candidates typically experience constant pain, limited mobility, and stiffness that affects daily activities and sleep.
It's recommended when X-rays show significant joint damage and deformity. Patients should have realistic expectations about outcomes and be medically fit for surgery.
What is arthroscopic knee surgery?
03
Arthroscopy is a minimally invasive procedure using small incisions and a camera. It allows surgeons to diagnose and treat problems like torn meniscus, loose cartilage, and inflamed synovium.
Benefits include less tissue damage, reduced pain, and faster recovery. However, it's not suitable for advanced arthritis where joint replacement may be needed.
How long does knee replacement last?
04
Modern knee replacements typically last 15-20 years. Approximately 85-90% of implants remain functional after 20 years. Longevity depends on patient activity level, weight, and implant type.
Younger patients may require revision surgery sooner. Technological advances continue to improve implant durability. Proper surgical technique significantly impacts longevity.
What is the recovery time after knee surgery?
05
Recovery varies: Arthroscopy patients resume normal activities in 6-8 weeks. Partial knee replacement requires 3-6 months. Total knee replacement needs 6-12 months for full recovery.
Most patients walk with assistance within 24 hours. Physical therapy begins immediately. Full recovery depends on following rehabilitation protocols.
What are the risks of knee replacement surgery?
06
Potential complications include infection, blood clots, implant failure, and nerve damage. Less common risks include stiffness, persistent pain, and allergic reactions to materials.
Modern techniques have reduced risks significantly. Preoperative optimization and experienced surgeons minimize complications. Blood thinners prevent clots post-surgery.
What is minimally invasive knee replacement?
07
This technique uses smaller incisions (4-6 inches vs 8-12 inches) and specialized instruments. It preserves quadriceps muscle and causes less tissue trauma.
08
Benefits include less blood loss, reduced pain, and faster recovery. However, it's not suitable for all patients, especially those with severe deformity or obesity.
How soon can I walk after knee surgery?
08
Most patients stand and walk with assistance within 24 hours. After arthroscopy, walking without crutches typically takes 1-2 weeks. Total knee replacement requires walking aids for 4-6 weeks.
Full unassisted walking usually takes 4-8 weeks. Physical therapy is crucial for regaining mobility. Walking progression depends on individual healing.
What is the difference between total and partial knee replacement?
09
Total replacement replaces all three knee compartments. Partial replacement resurfaces only the damaged compartment. Partial preserves healthy bone and ligaments.
Partial has smaller incisions and faster recovery but is only suitable for localized arthritis. Total replacement provides more comprehensive solution for widespread damage.
What is ACL reconstruction surgery?
10
ACL reconstruction replaces the torn anterior cruciate ligament with a graft. Surgeons use tissue from the patient's patellar tendon, hamstring, or donor tissue.
The procedure restores knee stability and prevents further joint damage. It's typically arthroscopic with small incisions. Rehabilitation is extensive, taking 6-9 months.
What is the success rate of knee replacement surgery?
11
Success rates exceed 90% for significant pain reduction and functional improvement. Over 95% of implants remain functional after 10 years. Patient satisfaction is 85-90% after 15 years.
Success depends on patient selection, surgical technique, and rehabilitation. Most patients regain 90-120 degrees of motion and resume daily activities.
What is robotic knee replacement?
12
Robotic-assisted surgery uses 3D imaging and computer guidance for precise implant positioning. The surgeon controls the robotic arm during bone preparation.
Benefits include improved alignment accuracy and preservation of healthy tissue. This can lead to better function and longer implant life. It's not fully automated - surgeons maintain full control.
What physical therapy is required after knee surgery?
13
Therapy begins immediately after surgery. Initial focus includes swelling control, range-of-motion exercises, and weight-bearing progression. Patients typically need 6-12 weeks of formal therapy.
Home exercises continue for 6-12 months. Therapy progresses from basic movements to strengthening and functional training. Compliance is crucial for optimal recovery.
Can knee surgery be performed on elderly patients?
14
Yes, age alone isn't a contraindication. Elderly patients undergo successful knee replacements if they're medically fit. Benefits include pain relief and improved mobility.
Comprehensive preoperative assessment is crucial. Outcomes are excellent for seniors with proper rehabilitation. Improved mobility often enhances overall health and independence.
What is a knee osteotomy?
15
Osteotomy involves cutting and reshaping bones to shift weight away from damaged areas. It's primarily for younger patients with early-stage arthritis on one side of the knee.
This preserves natural joint function and delays replacement. Recovery takes 3-6 months. The procedure can provide 10-15 years of relief before replacement might be needed.
How is pain managed after knee surgery?
16
Multimodal approaches include nerve blocks during surgery, IV pain medication initially, then oral opioids for a few days. Non-opioid options include Tylenol, NSAIDs, and gabapentin.
Cryotherapy (cold therapy) and elevation help reduce swelling. Most patients transition to non-opioid pain management within 1-2 weeks. Preemptive pain control begins before surgery.
What are the alternatives to knee replacement?
17
Options include physical therapy, weight management, injections (cortisone, hyaluronic acid), regenerative medicine (PRP, stem cells), and arthroscopic debridement.
For younger patients, cartilage restoration or osteotomy may be alternatives. However, these don't reverse advanced arthritis and may delay rather than replace the need for replacement.
What activities can I do after knee replacement?
18
Most patients resume walking, swimming, cycling, golf, and low-impact activities. High-impact sports like running and jumping are generally discouraged.
Activities should be pain-free and approved by your surgeon. Proper technique and gradual progression are essential. Implant longevity decreases with high-impact activities.
How do I prepare for knee surgery?
19
Preparation includes medical clearance, stopping certain medications, prehabilitation exercises, arranging home support, and preparing your recovery space.
Stop smoking, optimize nutrition, and practice using assistive devices. Complete dental work beforehand to prevent infection. Mental preparation is equally important.
What is revision knee replacement?
20
Revision surgery replaces a failed or worn-out knee implant. Causes include implant loosening, infection, instability, or fracture. It's more complex than primary replacement.
Recovery is longer with more restrictions. Specialized implants and bone grafts are often needed. Success rates are good but slightly lower than first-time replacements.
What is the role of weight management in knee surgery?
21
Excess weight increases surgical risks and implant failure rates. Many surgeons require BMI <40 for surgery. Weight loss reduces stress on new joints and improves outcomes.
Weight management is crucial both preoperatively and postoperatively. Even 5-10% weight reduction significantly decreases complication risks and improves function.
What are the different types of knee implants?
22
Common materials include cobalt-chromium alloys, titanium, and medical-grade polyethylene. Designs include fixed-bearing, mobile-bearing, posterior-stabilized, and cruciate-retaining.
Gender-specific and custom implants are available. Implant choice depends on anatomy, bone quality, and surgeon preference. All modern implants are MRI-compatible.
How long will I stay in the hospital after knee replacement?
23
Most patients stay 1-3 nights. Same-day discharge is possible for select patients with strong support. Factors include age, health status, and progress with physical therapy.
Extended stays may be needed for complications. Recovery facilities offer intermediate care for patients needing more therapy before home discharge.
What are the signs of a successful knee surgery?
24
Key indicators include progressive pain reduction, improved range of motion, ability to walk without aids, and return to daily activities. X-rays show proper implant positioning.
Successful surgery eliminates night pain and reduces dependence on pain medication. Patients report satisfaction with outcomes at 6-12 months post-surgery.
