Knee Arthroscopy
Minimally invasive keyhole surgery to inspect, diagnose, and treat conditions inside the knee joint.

Overview
Knee arthroscopy is a common minimally invasive keyhole procedure. This page explains what the surgery involves, suitability, and typical recovery stages.
Knee arthroscopy is a keyhole surgical procedure where a tiny camera (arthroscope) and specialized instruments are inserted through small incisions (portals) around the knee. This allows direct visualization and treatment of internal structures. Wording is cautious: arthroscopy is not a treatment for general arthritis, and is reserved for specific mechanical issues.
This information is for general patient education and does not replace an individual clinical assessment. Suitability and outcomes depend on joint condition and physical health.
Clinical Overview Illustration
What does this treatment involve?
Typical clinical stages of this treatment pathway include:
1Preoperative assessment, general or spinal anaesthetic, and surgical preparation
2Making two or three small incisions (portals) around the kneecap
3Inflating the joint with sterile fluid to provide a clear view of structures
4Inspecting ligaments, menisci, and articular cartilage surfaces
5Performing meniscal trimming, loose body removal, or cartilage debridement
6Closing portals with sutures or adhesive strips, and applying compression dressing
Suitability
Suitability depends entirely on an individual clinical examination, diagnostic imaging, medical history, and personal activity goals.
Who may benefit?
- Patients with mechanical joint locking due to meniscal tears or loose bodies
- Symptomatic cartilage flaps or localized cartilage defects failing rehab
- Persistent joint swelling or mechanical catching with clear pathology on MRI
When might it not be suitable?
- Widespread, advanced knee osteoarthritis with general pain and no mechanical blocks
- Severe systemic infection or active localized skin infection at portal sites
Alternatives
Alternative treatment pathways that may be considered depending on clinical severity:
Structured physical therapy and quadriceps strengtheningExplore Option >
Therapeutic joint injections (steroid or lubrication)Explore Option >
Joint replacement procedures if widespread arthritis is the cause of painExplore Option >
Risks
As with any clinical intervention, risks and complications differ between patients. Suitability and risk profiles are discussed in detail during consultation. General risks associated with this procedure include:
Deep vein thrombosis (DVT) or blood clots in the leg
Joint infection (septic arthritis) requiring urgent surgery
Persistent pain, joint swelling, or stiffness
Numbness around portal incisions due to minor nerve irritation
Recovery & Rehabilitation
Post-treatment rehabilitation and timelines are key to restoring joint health. We do not provide guaranteed recovery times.
Immediate Recovery
- Crutches may be required for 1 to 5 days depending on the procedure performed
- Portal wounds must be kept clean and dry for 10-14 days until sutures are removed
- Most patients can return to desk work in 1-2 weeks, and light driving in 1-2 weeks
- Full return to high-impact sports typically requires 6-12 weeks
Rehabilitation Pathway
- Early phase: ankle pumps and straight-leg raises to prevent swelling and DVT
- Mid phase: restoring full range of knee bending and extension
- Late phase: progressive quad and hamstring strengthening with physical therapy
Rehabilitation Milestones

Typical phase-based progression and return to functional activity guidelines.
1
Phase 1 (Early Stage)
Immediate Recovery & Adaptation
Primary Focus:Pain control, local tissue protection, and load modification.
- Crutches may be required for 1 to 5 days depending on the procedure performed
- Portal wounds must be kept clean and dry for 10-14 days until sutures are removed
- Most patients can return to desk work in 1-2 weeks, and light driving in 1-2 weeks
- Full return to high-impact sports typically requires 6-12 weeks
2
Phase 2 (Active Rehab)
Strength & Movement Restoration
Primary Focus:Targeted exercise to rebuild joint capacity and confidence.
- Early phase: ankle pumps and straight-leg raises to prevent swelling and DVT
- Mid phase: restoring full range of knee bending and extension
- Late phase: progressive quad and hamstring strengthening with physical therapy
Important Clinical AdviceRecovery timelines are indicative. Individual rehabilitation progression depends on surgical findings, tissue quality, and the specific guidance of your consultant orthopaedic surgeon and physiotherapist.

Frequently Asked Questions
No. High-quality clinical trials show that keyhole surgery is not effective for washing out or curing general osteoarthritis. It is only useful if there is a distinct mechanical block like a torn meniscus.
You can typically return to driving in 1-2 weeks, once you can safely perform an emergency stop and are no longer taking strong painkillers.
