BACKGROUND: @entity1843 ( @entity1843 ) can progress to @entity79 . The efficacy of internal fixation of chondral loose bodies has not been determined. HYPOTHESIS: Operative fixation of cartilaginous loose bodies would result in (1) healed @entity1843 at second-look arthroscopy, (2) restored cartilage appearance on magnetic resonance imaging (MRI), and (3) nearly normal knee function, as determined by @entity1 -reported outcome scores. STUDY DESIGN: Retrospective case series; Level of evidence, 4. METHODS: Five @entity1 who underwent cartilaginous @entity12458 were identified. Lesions were located on the lateral trochlea (n = 2) and medial femoral condyle (n = 3) (mean size, 2.5  cm(2)). Loose bodies were reattached with compression screws through mini-arthrotomy or arthroscopy. @entity1 were nonweightbearing for 12 weeks postoperatively. After 12 weeks, screws were removed arthroscopically, and @entity1843 stability was evaluated. Three @entity1 underwent MRI to determine articular cartilage status. Images were evaluated using the magnetic resonance observation of cartilage repair tissue (MOCART) score. @entity1 were interviewed and completed the @entity3331 and @entity571 Outcome Score (KOOS) questionnaire. RESULTS: Four @entity1 had stable lesions at 12 weeks after surgery. One @entity1 had slight motion to one-third of the lesion and stability to the remaining two-thirds. Three @entity1 underwent an MRI. The mean time from surgery to MRI was 3.1 years. Mean MOCART score was 72.0    10.4. One @entity1 required repeat arthroscopy 1 year after initial fixation for debridement and arthroscopic drilling of an incompletely healed area of the lesion. Four @entity1 completed the KOOS questionnaire. The mean time to KOOS completion was 4.6 years. Mean KOOS subscales for knee @entity158 (91.0    8.9), knee symptoms (83.0    7.9), and function in activities of daily living (91.9    10.6) were similar to published age-matched controls; however, scores for sports and recreation function (70.0    17.8) and knee-related quality of life (67.2    12.9) were lower. CONCLUSION: Operative fixation of chondral loose bodies, without macroscopically visible subchondral bone attachment, resulted in lesion stability at second-look arthroscopy. At final follow-up, @entity1 had no substantial @entity158 and normal function in activities of daily life compared with controls; however, knee-related quality of life and sport and recreation function were reduced, and 1 @entity1 required reoperation for an unhealed portion of the lesion.
