The goal of the study was to report the prevalence of the lesions of the articular cartilage of the femoral condyles and tibial plateau in patients with a symptomatic anterior cruciate ligament (ACL)-deficient knee undergoing day-case arthroscopy. ⋯ In patients with more advanced degenerative changes, the time from injury to arthroscopy was significantly longer than in patients with lesser articular surface abnormalities, and the presence of a meniscal tear was associated with a greater degree of articular cartilage damage. Patients with a symptomatic ACL-deficient knee and an associated tear of the medial meniscus are at high risk of having a lesion of the articular surface of the weight bearing area of the knee.

Comparative Study
Patellar tendon versus quadrupled bone-semitendinosus anterior cruciate ligament reconstruction: a prospective clinical investigation in athletes.
Patellar tendon and hamstrings are both used in anterior cruciate ligament (ACL) reconstruction, and comparisons have been reported with different results. The purpose of this clinical study was to compare the results of ACL reconstruction in athletes with 2 different graft types, both using bone-to-bone healing: bone-patellar tendon-bone graft and a quadrupled bone-semitendinosus graft. ⋯ The bone-patellar tendon-bone and quadrupled bone-semitendinosus autograft provide excellent grafts for ACL reconstruction. Both techniques are comparable regarding final stability, but in patients with extensor mechanism problems or those who engage in sports with a high incidence of patellar tendonitis, the semitendinosus graft should be considered.

Case Reports Comparative Study
Detachment of the tip of a motorized shaver within the knee joint: a complication of arthroscopic surgery.
In arthroscopic procedures, instrument failures are rare complications with low incidences. We present a case of detachment of the tip of the motorized shaver within the knee joint during an arthroscopic anterior cruciate ligament reconstruction procedure. ⋯ We did not realize that the tip was missing within the knee joint during the surgery. We believe that the design of the shaver blade that was used needs modification, and surgeons must take special precautions to inspect the instrument before and after placing it in the joint.

To evaluate the load to failure and the mode of failure of a novel suture anchor construct that does not require knots (the "twist-lock" construct) and to compare it with a standard suture anchor construct (Corkscrew; Arthrex, Naples, FL). ⋯ The twist-lock system is a suture anchor system that achieves suture fixation of soft tissue to bone without the need to tie knots. It shows single-pull loads to failure that are significantly higher than those of a standard suture anchor system.

Clinical Trial Controlled Clinical Trial
Patient-controlled bupivacaine infusion into the infrapatellar fat pad after anterior cruciate ligament reconstruction.
The goal of the study was to determine the safety and analgesic efficacy of a patient-controlled infusion pump that dispenses bupivacaine extra-articularly to the infrapatellar fat pad after anterior cruciate ligament (ACL) reconstruction with ipsilateral bone-patellar tendon-bone autogenous graft. ⋯ Infrapatellar fat pad infusion with 0.5% bupivacaine may provide enhanced analgesia after ACL reconstruction with ipsilateral bone-patellar tendon-bone autogenous graft. A double-blinded, randomized control trial with a greater number of patients is required to confirm these findings.
