Lysholm Knee Scale
Lysholm Knee Scoring Scale · Also known as: Lysholm, Lysholm-Gillquist Scale
The Lysholm Knee Scoring Scale is an 8-item knee outcome instrument developed by Swedish orthopedic surgeons Lysholm and Gillquist in 1982 to evaluate knee ligament surgery results. Published in the American Journal of Sports Medicine, the Lysholm Scale was among the first validated knee outcome measures and remains widely used in clinical practice and orthopedic research, particularly in studies of anterior cruciate ligament injuries and knee ligament reconstruction.

When to use it
The Lysholm Scale is indicated for patients with knee ligament injuries (particularly ACL tears) and post-reconstruction rehabilitation. It is especially valuable in settings with longitudinal ACL cohort data, as many published studies from the 1980s–2010s used Lysholm as their outcome measure, allowing historical comparisons. The Lysholm is less comprehensive than modern scales like the IKDC (which has 18 items and stronger psychometric data), but its brevity is advantageous in high-volume clinics or when rapid assessment is needed. Use Lysholm when historical continuity with previous literature is important, or when time constraints limit use of longer scales. For new studies without historical anchors, consider IKDC as the preferred alternative.
Strengths & limitations
- Excellent test–retest reliability (ICC 0.84–0.94) and internal consistency; well-validated in ACL injury and knee ligament populations over four decades of clinical use.
- Brief (8 items) and rapid administration (5–10 minutes); straightforward scoring yields 0–100 scale with clinically intuitive thresholds (poor/fair/good/excellent).
- Highly responsive to knee ligament surgery outcomes; sensitive to improvements from ACL reconstruction and physical rehabilitation; widely used in orthopedic literature, enabling historical comparison and meta-analysis.
- No cost, no copyright restrictions, freely available in multiple languages; easily implementable in paper or electronic format.
- Less comprehensive than modern scales; 8 items is brief but may miss nuances captured by IKDC's 18 items (e.g., activity-specific function, sport readiness differentiation).
- Primarily validated in ACL injury populations; validity in other knee pathologies (meniscal injury, osteoarthritis, patellar pain) is less robust than disease-specific scales.
- Ordinal response options (e.g., 'limp: slight vs. moderate') are subjective and may be interpreted differently by patients; no visual anchors or examples provided.
- Scoring can be error-prone if performed manually; precise point values for each response option must be followed; electronic scoring is strongly recommended.
Frequently asked
How does the Lysholm Scale differ from the newer IKDC Subjective Knee Form?
Lysholm has 8 items and a simpler structure; IKDC has 18 items and is more comprehensive. IKDC is more responsive to change and has stronger modern validation data. Lysholm is preferred for historical continuity (older literature used Lysholm) or when time is limited. IKDC is preferred for new research without historical anchors. Both are valid; choose based on your study's needs.
What is the minimal clinically important change (MCID) on the Lysholm Scale?
Published MCID data are limited; an estimated change of 5–10 points is considered clinically meaningful, with >15 points indicating substantial improvement. Context matters: in an athlete post-ACL surgery, improvement from 45 to 75 (+30) is clearly meaningful; improvement from 85 to 90 (+5) in a patient already doing well may be within measurement error.
Should I use Lysholm or IKDC for my new ACL reconstruction study?
For a new study without historical data to compare, use IKDC; it is the modern standard with better validation and responsiveness. Use Lysholm only if you need to compare with historical Lysholm data (e.g., matching a 1995 cohort) or if time/resource constraints are severe. If possible, administer both IKDC and Lysholm to allow future researchers to map your data to other studies.
Can I use Lysholm for non-ACL knee conditions like meniscal injury or osteoarthritis?
Lysholm is primarily validated in ACL populations and is less robust in other knee pathologies. For meniscal injury or OA, consider condition-specific scales (e.g., FAOS for foot/ankle, or KOOS for knee OA, which is similar to IKDC structure). If Lysholm is used, validate its appropriateness for your specific knee condition and report limitations.
