Arthroscopic Knee Surgery Alternatives in KL: Practical Options

Arthroscopic knee surgery to trim a worn meniscus has been tested against a sham operation, in which the surgeon only pretended to cut, and ten years later the people who had the real operation were no better off, with signs of more arthritis and more later operations.

The operation is done through two or three short cuts beside the kneecap, most often to trim a torn meniscus or to wash out and smooth a worn joint. In placebo-controlled trials published in the New England Journal of Medicine, neither use did better than a pretend operation, and national hospital records link meniscus trimming with a higher chance of a knee replacement in the years that follow.

In CSC’s view, the practical options come first: a precise examination and MRI review; gentle Activator adjustment where the kneecap, the thighbone on the shinbone or the top of the fibula sits out of alignment; laser, shockwave, ultrasound, electrotherapy and soft tissue work where the findings call for them; and graded exercise. Keyhole surgery belongs after a proper course of that care, from a provider thoroughly familiar with knee physiotherapy, knee chiropractic care, knee rehabilitation and knee exercise, has not helped.

Arthroscopic Knee Surgery: Key Takeaways

Point	What to know
What a sham trial found	In a Finnish trial of 146 adults with a worn medial meniscus, trimming the meniscus did no better than a sham operation at 12 months (Sihvonen et al., 2013).
Ten years later	The trimmed knees scored worse on a meniscus symptom questionnaire, and 8 people in the trimmed group, against 3 in the sham group, had gone on to a knee replacement or an operation to realign the shinbone (Kalske et al., 2026).
Washing out a worn knee	Washing out and smoothing an arthritic knee did no better than a placebo operation over two years (Moseley et al., 2002).
A knee replacement later	Of 834,393 people in England who had a meniscus trimmed, 13.5% of those followed for 15 years had a knee replacement, and the operated knee was replaced three times as often as the other knee (Abram et al., 2019).
What comes first	A thorough assessment and a proper course of conservative care from a provider thoroughly familiar with knee physiotherapy, knee chiropractic care, knee rehabilitation and knee exercise. Keyhole surgery is weighed only if that care has not helped.
When a surgical opinion is needed sooner	A knee that is truly locked and cannot straighten, an unstable bucket-handle tear, a loose fragment inside the joint, or a complete ligament rupture with a knee that keeps giving way.
Questions to ask before agreeing	What did sham-controlled trials find for this operation, what is the chance of another operation or a knee replacement in the next 10 to 15 years, and what would a proper course of conservative care involve first?

What the New England Journal of Medicine Found About Arthroscopic Knee Surgery

Two reports in the New England Journal of Medicine come from the same Finnish trial, and together they answer the question that matters most before keyhole surgery: does the operation do anything that a pretend operation does not?

2013: Meniscus trimming against a sham operation

Five orthopedic clinics in Finland enrolled 146 adults aged 35 to 65 whose knee pain from a worn medial meniscus had lasted more than three months and had not settled with conventional conservative treatment. None had knee arthritis. A camera was first passed into every knee, and only then was a sealed envelope opened in the operating room: 70 people had the torn meniscus trimmed, and for 76 the surgeon went through the motions without trimming anything, asking for the instruments, moving the knee as if operating, pressing a bladeless shaver against the outside of the kneecap and running the suction. Neither the patients nor the people measuring their progress knew who had which.

A year later, the sham group had improved just as much as the trimmed group on all three main measures (two knee scores and pain after exercise), so the improvement did not come from the trimming. The authors wrote that their results argue against the practice of trimming a degenerative meniscal tear (Sihvonen et al., N Engl J Med. 2013;369(26):2515-2524). The journal offers the full article as a free PDF.

2026: The same patients ten years on

In April 2026 the journal published the ten-year results, with nine in ten patients in each group still followed. The trimmed knees now scored worse than the sham-operated knees on the meniscus questionnaire. Arthritis had progressed on X-ray in 81% of the trimmed group against 70% of the sham group, and 8 people who had their meniscus trimmed had gone on to a knee replacement or a high tibial osteotomy (an operation that realigns the shinbone), against 3 in the sham group. The authors found no evidence of benefit from the operation and a suggestion of worse outcomes (Kalske et al., N Engl J Med. 2026;394(17):1757-1759). Lund University holds a free copy of the authors’ accepted version.

How often a knee replacement follows keyhole surgery

Outside trials, national hospital records show where knees go after the operation. In England, 834,393 people who had a meniscus trimmed were tracked for up to 20 years: of those followed for at least 15 years, 13.5% had a knee replacement (22% of women and 10% of men), and the operated knee was replaced three times as often as the same person’s other knee (Abram et al., 2019). In a second English study, about 1 in 10 people aged 60 or older had a knee replacement within a year of the trimming (Abram et al., 2019). A review of 20 studies of keyhole surgery for knee arthritis found that about 2.5% of patients a year went on to a knee replacement, typically around two years after the keyhole operation (Winter et al., 2017). The review is open access, and a copy of the full review can be downloaded here as a PDF.

Records like these show who went on to a replacement rather than proving that the operation caused it. The Finnish trial, in which chance alone decided who was operated on, pointed the same way.

Three questions to ask before agreeing to keyhole surgery

What did the sham-controlled trials find for the operation being offered?
What is the chance of a further operation or a knee replacement in the next 10 to 15 years?
What would a proper course of conservative care, from a provider skilled in knee physiotherapy, knee chiropractic care, knee rehabilitation and knee exercise, involve first?

Arranging a Knee Assessment Before Arthroscopic Surgery

A second opinion before keyhole surgery starts with an examination rather than a scan. The first visit covers how the pain began and what it stops the knee from doing; how the knee moves, swells and takes weight; tests of the menisci and ligaments; the position of the kneecap, of the thighbone on the shinbone and of the top of the fibula; and the hip, ankle and foot. Any MRI report is read against those findings before the options are discussed. Either Kuala Lumpur center can arrange it:

Do You Need Arthroscopic Knee Surgery or Can Non-Surgical Care Be Tried First?

For meniscus irritation, cartilage wear, kneecap tracking problems, swelling, catching or stiffness, CSC’s view is that a specific course of conservative care comes before any keyhole operation, for the reasons the trials above set out.

For a practical explanation of knee loading, imaging, exercise, and conservative care decisions, watch Knee Pain Causes and Exercises Explained.

Ligament injuries are different. A complete ACL rupture in a person who wants to return to an active life, some PCL and lateral-corner injuries, and an avulsion fracture, where a ligament pulls away a piece of bone, often need a surgical opinion, especially when the knee keeps giving way. Most MCL injuries heal without surgery.

The question that matters is not whether non-surgical care was tried, but whether it was matched to the exact tissue involved, the person’s age and activity, the examination findings and the imaging, and whether it came from a provider thoroughly familiar with knee physiotherapy, knee chiropractic care, knee rehabilitation and knee exercise. The main knee pain guide sets out how each part of the knee is assessed.

How CSC Approaches a Knee Before Keyhole Surgery Is Considered

The examination looks past the scan to how the knee is aligned and how it takes load: how the kneecap tracks in its groove, how the thighbone sits and glides on the shinbone, how the top of the fibula moves against the shinbone, and how the hip, ankle and foot pass force up to the knee.

Where one of those joints sits out of alignment, it is corrected with gentle Activator adjustments, never forceful or aggressive manipulation. Soft tissue work and, where the findings call for them, laser, shockwave, ultrasound or electrotherapy are added, and graded strengthening runs alongside. Exercise matters, but on its own it does not bring a kneecap or a joint back into alignment, which is why the two are combined. The treatment methods used at CSC are described one by one on their own pages, and the video below explains how the knee’s structures share load and where knee pain most often starts.

How Long Should Non-Surgical Knee Care Be Tried First?

The timing depends less on the number of weeks and more on how accurate the care plan is.

Non-surgical knee care is planned around the structure involved, using the symptoms, the clinical examination, age, activity demands, joint stability and, when needed, MRI findings for the meniscus, cartilage, ligaments and the bone beneath the cartilage.

A general exercise program alone is often not enough. The plan should match the tissue under stress and be reviewed as the knee responds. Only when a focused, well-supervised program has not brought meaningful improvement is a surgical review considered.

Why MRI Specificity Matters Before Knee Surgery

MRI helps clarify the exact structure involved before deciding between surgery and conservative care. It shows the meniscus, the cartilage surfaces, the ligaments, the bone beneath the cartilage and any swelling in the bone marrow, often in more detail than a standard report describes.

A tear on the scan is not always the source of the pain. In a study of 991 adults aged 50 to 90 in Framingham, Massachusetts, chosen without regard to knee problems, between 19% and 56% had a torn or worn meniscus on MRI depending on age and sex, and 61% of those with a tear had had no knee pain, aching or stiffness in the previous month (Englund et al., 2008). That is why the scan is read against the examination.

The depth of cartilage wear, the extent of bone marrow swelling, the location of cartilage cracks and the stability of a meniscal tear can each change whether a targeted non-surgical plan is still appropriate, and how rehabilitation, joint mobilization and exercise are progressed.

What Other Research Shows About Arthroscopy for Worn Knees

Washing out and smoothing an arthritic knee was tested the same way. In a Houston trial of 180 people with knee osteoarthritis, those who had the joint washed out, or washed out and smoothed, reported no less pain and no better function at any point over two years than those who had a placebo operation of skin cuts alone (Moseley et al., 2002). A Canadian trial then added washout and smoothing to a program of physical and medical therapy and found no additional benefit at two years (Kirkley et al., 2008).

A review that pooled the trials of keyhole surgery for worn knees concluded that they do not support the operation for middle-aged and older people with knee pain, with or without arthritis: no benefit remained at one to two years, and the harms recorded included blood clots and infection (Thorlund et al., 2015).

The meniscus spreads load across the joint, and removing part of it leaves the cartilage beneath carrying more. At five years, the Finnish trial found a slightly higher risk of arthritis on X-ray in the trimmed knees, more mechanical symptoms in that group and no benefit (Sihvonen et al., 2020), and a US study found that knees which had part of a meniscus removed were more likely to show new arthritis and worsening cartilage damage within a year (Roemer et al., 2017).

Exercise has also been compared with the operation directly. In a Dutch trial of 321 people aged 45 to 70 with a degenerative meniscal tear, 16 sessions of exercise therapy over eight weeks did not fall short of meniscus surgery for knee function at two years or at five years, and the researchers concluded that physical therapy should be the preferred treatment (van de Graaf et al., 2018; Noorduyn et al., 2022). Which exercises suit which knee is covered in the knee exercises guide.

When Arthroscopic Knee Surgery May Still Be Considered

A surgical opinion is sought sooner when one of these is present:

a knee that is truly locked and cannot be straightened
an unstable bucket-handle meniscus tear
a loose fragment inside the joint
repeated giving way from a complete ligament rupture
a ligament avulsion injury

For a worn meniscus or an arthritic knee, CSC’s position is that keyhole surgery comes only after a thorough assessment and a proper course of conservative care from a provider thoroughly familiar with knee physiotherapy, knee chiropractic care, knee rehabilitation and knee exercise, and only if that care has not helped. The decision itself is made with an orthopedic surgeon.

Arthroscopic Knee Surgery: Common Questions Before You Decide

When is arthroscopic knee surgery usually considered?

In CSC’s view, only after a thorough assessment and a proper course of conservative care from a provider thoroughly familiar with knee physiotherapy, knee chiropractic care, knee rehabilitation and knee exercise has not helped. A knee that is truly locked, an unstable meniscus tear or a loose fragment inside the joint calls for a surgical opinion sooner.

Can physiotherapy be considered before arthroscopic surgery?

Yes, and in CSC’s view it should come first. For a degenerative meniscal tear or a worn knee, physiotherapy is combined with gentle chiropractic care where alignment needs correcting, rehabilitation and graded exercise, and surgery is weighed only if that care has not helped.

What does long-term research say about surgery vs rehabilitation?

In the Finnish sham-controlled trial, trimming a worn meniscus did no better than a pretend operation at one year, and at ten years the trimmed knees showed signs of more arthritis and more later operations. In a Dutch trial, 16 sessions of exercise therapy did not fall short of the operation for knee function at two and five years.

Can knee tracking problems mimic meniscus symptoms?

Yes. Patellar maltracking, quadriceps imbalance, glute weakness, hip instability, and movement dysfunction may sometimes create symptoms that overlap with meniscus irritation.

When should imaging such as MRI be considered?

MRI may be helpful when symptoms persist, locking is present, swelling continues, or deeper structures such as the meniscus, cartilage, ACL, or subchondral bone need evaluation.

Can surgery still be necessary?

Yes, in some cases. A knee that is truly locked, an unstable meniscus tear, a loose fragment in the joint or a complete ligament rupture with a knee that keeps giving way needs a surgical opinion. For a worn meniscus or an arthritic knee, surgery is considered only after a proper course of conservative care has not helped.

Do all meniscus tears need arthroscopic surgery?

No. Many meniscus tears seen on MRI cause no pain at all, and most meniscus-related symptoms are first treated with structured, condition-specific conservative care, depending on the tear’s stability and location, the cartilage, and whether the knee truly locks.

How long should I try non-surgical knee care first?

The focus should be on the accuracy and specificity of care rather than time alone. A structured plan based on symptoms, examination findings, and MRI review is usually assessed over several weeks before surgical review is considered.

Should every ligament tear be managed without surgery?

No single rule applies. Most MCL injuries heal without surgery. Complete ACL ruptures with ongoing instability, some PCL and lateral-corner injuries, and avulsion fractures more often need a surgical opinion, particularly when the knee repeatedly gives way.

Why is MRI important before deciding on knee surgery?

MRI shows meniscal tears, cartilage wear, ligament injuries and bone swelling, but it has to be read against the examination: in a study of 991 adults aged 50 to 90, 61% of those with a meniscal tear on MRI had no knee pain, aching or stiffness in the previous month.
