Postoperative analgesia in patients older than 75 years undergoing intervention for per-trochanteric hip fracture: a single centre retrospective cohort study.

The aim of this study was to compare the efficacy of four analgesia techniques on postoperative pain after per-trochanteric femur fracture. A retrospective cohort study was conducted on 131 consecutive patients older than 75 years enrolled in an 18-month period and who underwent per-trochanteric fracture repair under spinal analgesia. Patients received postoperative analgesia from: G1 (n = 36), intravenous analgesia on demand only; G2 (n = 28) administration of acetaminophen at fixed hours; G3 (n = 50) continuous morphine infusion; G4 (n = 17), preoperative echo-graphic guided femoral nerve block.

Comparison between single-and double-bundle anterior cruciate ligament reconstruction: a prospective, randomized, single-blinded clinical trial.

Background: Double-bundle ACL reconstruction popularity is increasing with the aim to reproduce native ACL anatomy and improve ACL reconstruction outcome. However, to date, only a few randomized clinical studies have been published.

Purpose: The aim of this study was to prospectively compare the clinical results of single- and double-bundle ACL reconstruction.

Rotational position of femoral and tibial components in TKA using the femoral transepicondylar axis.

Proper femoral and tibial component rotational positioning in TKA is critical for outcomes. Several rotational landmarks are frequently used with different advantages and limitations. We wondered whether coronal axes in the tibia and femur based on the transepicondylar axis in the femur would correlate with anteroposterior deformity.

Methodological models for in vitro amplification and maintenance of human articular chondrocytes from elderly patients.

Articular cartilage defects, an exceedingly common problem closely correlated with advancing age, is characterized by lack of spontaneous resolution because of the limited regenerative capacity of adult articular chondrocytes. Medical and surgical therapies yield unsatisfactory short-lasting results. Recently, cultured autologous chondrocytes have been proposed as a source to promote repair of deep cartilage defects.

Anterior cruciate ligament reconstruction with double-looped semitendinosus and gracilis tendon graft directly fixed to cortical bone: 5-year results.

Forty-three patients who had undergone an anterior cruciate ligament (ACL) reconstruction using a doubled semitendinosus and gracilis graft were prospectively reviewed at 5-year follow-up. All had suffered subacute or chronic tears of the ligament. At surgery, the femoral tunnel was drilled first through the antero-medial portal.
