Lysholm Knee Scoring System

Lysholm Knee Score

One of the most common reasons for knee surgery is an injury to a person’s Anterior Cruciate Ligament (ACL). With that in mind, the Lysholm Knee Score is one of the most utilized scoring systems for ACL injuries and chondral defects. The first version of the Lysholm scale was published in 1982 and consisted of eight questions that dealt with the categories of limping, support, locking, instability, pain, swelling, stair climbing, and squatting. A revised version of Lysholm was introduced in 1985 and added one item regarding knee locking while removing other items relating to pain/swelling on giving way, the objective measurement of thigh atrophy, and the reference to walking, running, and jumping.

Following these modifications, the Lysholm scoring scale reached the standard required to become a patient-reported outcome measure (PROM), and as with all PROMs, the modified questionnaire enhanced patient perspectives of their illness.

The Lysholm Scale currently consists of eight items that measure: pain (25 points), instability (25 points), locking (15 points), swelling (10 points), limp (5 points), stair climbing (10 points), squatting (5 points), and need for support (5 points). Every question response has been assigned an arbitrary score on an increasing scale. The total score is the sum of each response to the eight questions and may range from 0-100. Higher scores indicate a better outcome with fewer symptoms or disabilities.


The Lysholm Knee Scoring Scale has an extended use beyond evaluating outcomes of knee ligament surgery. It can also be used for meniscal tears, knee cartilage lesions, osteochondritis dissecans, traumatic knee dislocation, patellar instability, patellofemoral pain, and knee osteoarthritis.

A study carried out by Briggs et al. showed the Lysholm questionnaire to have acceptable test-retest reliability, floor and ceiling effects, criterion validity, construct validity, and responsiveness to change [2]. Finally, the questionnaire itself is relatively easy for patients to complete and does not have a complicated scoring methodology.


The Lysholm scale appears to have inadequate internal consistency in patients with a variety of knee conditions and although test–retest reliability is adequate for use in groups with knee injuries, studies have found that it is less than adequate for patients with mixed knee pathologies.


The Lysholm PRO Measure does not require a license and is free to use.
