“…In patients over the age of 50, bone-patellar tendonbone autograft, hamstring tendon autograft, and quadriceps allograft are typically used in the reconstruction of ACL rupture (2,3,(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(22)(23)(24)(25). Details on the application of these artificial grafts have not yet been reported; however, autologous grafts have a number of well-documented drawbacks, including donor site morbidity and a delayed recovery to preinjury levels (26)(27)(28).…”

Background With the increasing physical activity level in elderly population, anterior cruciate ligament (ACL) injuries are becoming more frequent. Due to the possible surgery complications, treatment for ACL rupture in patients with advanced age is still controversial. The purpose of this study was to compare the therapeutic effects of reconstruction using the ligament advanced reinforcement system (LARS) artificial ligament in patients older than 50 and patients younger than 50 with chronic ACL rupture. Methods Indications included: (I) concurrent history of subjective symptomatic anterior knee instability despite nonoperative rehabilitation for least 3 months, (II) positive preoperative Lachman and pivot shift tests, (III) ACL stump still connecting the femur with the tibia as demonstrated by Magnetic Resonance Imaging (MRI), and (IV) some residual ligament fibers still connecting the femur with the tibia as demonstrated by arthroscopy. Participants were divided into groups based on their age. Participants were divided into groups based on their age. A total of 37 patients who underwent reconstruction of chronic ACL rupture using the LARS artificial ligament were divided into group A (≥50 years, n=16) and group B (<50 years, n=21). Results The outcome measures were compared between the 2 groups. These included the baseline clinical data, the International Knee Documentation Committee (IKDC) scoring system, Pivot shift test, Lachman test, Kneelax arthrometer measurements, Tegner activity scale, Lysholm knee scoring scale, and Kellgren-Lawrence radiographic classification of arthritis and complications. Postoperative knee laxity and the functional examination were significantly improved compared to preoperative measurements for both groups (all P<0.01). No significant differences were found in postoperative knee laxity and functional examination between the 2 groups (all P>0.05). The level of osteoarthritis did not statistically increase in either group during follow-up (all P>0.05). No complications associated with the arthroscopic surgery were found in either group. Conclusions The reconstruction of chronic ACL rupture using the LARS artificial ligament showed similar therapeutic effects in patients over the age of 50 and those under the age of 50.
