Trial overview
The provided trial studied Autologous Chondrocytes in a knee cartilage condition called a symptomatic articular cartilage lesion.[1] The study compared this treatment with conservative care, meaning non-surgical treatment such as optional physical therapy and pain medicine.[1]
This was a randomized controlled trial, which means patients were assigned by chance to a treatment group so the results could be compared fairly.[1] The trial was completed and included 60 participants.[1]
Who was studied
The target population was people with a symptomatic articular cartilage lesion of the knee.[1] The trial specifically mentions lesions in the femoral condyles or the trochlea, which are parts of the knee joint.[1]
In simple terms, this means the study focused on people whose knee cartilage damage was causing symptoms such as pain or reduced function.[1]
What was tested
The intervention in the trial was an intra-articular injection of Instant MSC Product accompanying Autologous Chondron Transplantation (IMPACT).[1] The source data list the dose as 1.4 ml/cm2 and describe it as an injection into the joint.[1]
The study compared IMPACT with standard care, which could include physical therapy and pain medication, but no surgical treatment.[1] The purpose was to see whether the treatment led to better clinical improvement and better quality of life than standard care.[1]
Outcomes measured
The main outcome was clinical improvement and quality of life after 3, 6, and 9 months.[1] These were measured using KOOS and EQ5D, which are questionnaires used to track knee-related symptoms and general health status.[1]
- KOOS: a questionnaire that helps measure knee symptoms, pain, daily activities, sports and recreation, and quality of life.[1]
- EQ5D: a questionnaire that helps measure general health and quality of life.[1]
Trial design and phase
The study was an interventional trial, which means the researchers actively gave a treatment and then measured the results.[1] It was in Phase 3, a later-stage phase that usually tests treatment effects in a larger group and compares them with another approach.[1]
The trial status is listed as completed, so the study has already finished collecting its data.[1]
What the results are meant to show for patients
For patients, this trial is mainly about whether Autologous Chondrocytes-related treatment can help people with knee cartilage damage feel better and live better in daily life.[1] The comparison with standard care helps show whether the treatment offers added benefit beyond non-surgical care.[1]
The study does not focus on many different diseases or patient groups; it is specifically about knee cartilage lesions with symptoms.[1] Based on the source data, the key question is not just whether the treatment can be given, but whether it improves patient-reported outcomes over time.[1]
