Anatomical reconstruction of the medial patellofemoral ligament using a free gracilis autograft.
Since biomechanical studies have shown that the medial patellofemoral ligament (MPFL) is the main restraint against lateral patella displacement, reconstruction of the MPFL has become an accepted surgical technique to restore patellofemoral stability. Recently, various procedures have been described that address reconstruction of the medial patellofemoral complex. We present a technique, where the MPFL is reconstructed anatomically to restore physiological kinematics and stability, using a free gracilis tendon autograft.

Traumatic anterior shoulder dislocation in toddlers and pediatric patients is a very rare injury pattern. The treatment and the recurrence rate are mostly extrapolated from adult and adolescent data. ⋯ The 2.5-year-follow-up demonstrated a stable shoulder with free range of motion while still having a Hill-Sachs-lesion. Shoulder dislocation in toddlers maybe addressed less aggressively after closed reduction than in adults due to an unknown recurrence rate.

A modified arthroscopic anterior cruciate ligament double-bundle reconstruction technique with autogenous quadriceps tendon graft: remnant-preserving technique.
Several techniques of anterior cruciate ligament (ACL) double-bundle reconstruction have been introduced to improve the functional outcome and restore normal kinematics of the knee. Meanwhile, a remnant-preserving technique was developed to preserve the proprioception and to enhance the revascularization of the reconstructed ACL. We developed double-bundle ACL reconstruction technique using autogenous quadriceps tendon graft while preserving the remnant. ⋯ To preserve the remnant of the ACL, the rotational direction of the reamer was set to counterclockwise just before perforation of the tibial tunnel. To pass the graft more easily without disturbance of the remnant, the graft passage was achieved through the tibial tunnel. We suggest that the remnant-preserving technique could be an effective alternative considering its mechanical stability as well as the proprioception and vascularization recovery in arthroscopic double-bundle ACL reconstruction.

Randomized Controlled Trial Comparative StudyPre-emptive intra-articular administration of local anaesthetics/opiates versus postoperative local anaesthetics/opiates or local anaesthetics in arthroscopic surgery of the knee joint: a prospective randomized trial.
Arthroscopic surgery on the knee joint is increasingly being performed as day-case surgery. This necessitates adequate postoperative pain therapy. We performed a study to compare three different intra-articular regimens of pain treatment. The hypothesis was that preoperative intra-articular pain management is superior to postoperative procedures. ⋯ This study demonstrated the superiority of the preoperative intra-articular administration of a combination of fentanyl and local anaesthetic over postoperative fentanyl and local anaesthetic or postoperative local anaesthetic alone.

Effects of articular cartilage and meniscus injuries at the time of surgery on osteoarthritic changes after anterior cruciate ligament reconstruction in patients under 40 years old.
The development of osteoarthritis (OA) after anterior cruciate ligament (ACL) reconstruction is an unsolved problem. Articular cartilage and meniscus injuries are particularly important factors that contribute to OA progression. ⋯ Level 4, case series, therapeutic studies, investigating the results of treatment.
