Randomized Controlled TrialIntraarticular tramadol plus pericapsular incisional bupivacaine provides better analgesia than intraarticular plus pericapsular incisional bupivacaine after outpatient arthroscopic partial meniscectomy.
Postoperative analgesic effects of intraarticular tramadol plus periarticular bupivacaine, and intraarticular plus periarticular bupivacaine injections after day-case arthroscopic partial meniscectomy were compared. Seventy-four ASA I/II patients undergoing arthroscopic partial meniscectomy, performed by a single surgeon under general anesthesia were assigned in a randomized, double-blinded manner into two groups: Group TB (n = 41) received intraarticular 100 mg of tramadol in 20 ml normal saline and periarticular incisional injection of 10 ml bupivacaine 0.5%. Group BB (n = 33) received intraarticular 20 ml 0.25% and periarticular incisional 10 ml 0.5% bupivacaine injections. ⋯ VAS scores at rest at 15, 30 min and at movement at 0, 15, 30 min were lower in group TB (P < 0.05). First time requiring additional analgesia was lower in group TB (17.1 +/- 21.9, 33.8 +/- 26.6) (P < 0.05) and total paracetamol dose at the end of 24 h was 1.2 +/- 1.5 g in group BB and 0.9 +/- 1.3 g in group TB (P < 0.05). Intraarticular tramadol plus periarticular bupivacaine combination provides better pain relief and less analgesic requirement following arthroscopic outpatient partial meniscectomy surgery.

Comparative StudySurgical treatment of type II floating knee: comparisons of the results of type IIA and type IIB floating knee.
The prognosis of type II floating knee injuries was not as good as that of type I. Our purpose is to clarify the factors affecting the outcome of type II floating knee injuries. Thirty-five patients (36 limbs) with type II floating knee injury were studied with a mean follow-up of 52 months (26-96). ⋯ Intra-articular knee involvement is the most important factor contributing to poor outcome of type II floating knee. The treatment of floating knee injuries with intra-articular knee involvement is still difficult. Further efforts to search better methods of treatment are required for these complex injuries in the future.

Treatment of Jumper's knee: promising short-term results in a pilot study using a new arthroscopic approach based on imaging findings.
Sclerosing injections targeting the area with neovessels and nerves on the dorsal side of the patellar tendon has been demonstrated as giving promising clinical results in patients with chronic painful Jumper's knee-patellar tendinosis (PT). However, a mean number of three treatments with 6-8 weeks in between were needed for a good clinical result. This study aimed to evaluate a more radical removal of the area with neovessels and nerves by using arthroscopic shaving. ⋯ A telephone follow-up 13 months (mean) postoperatively showed that the same 13/15 were still satisfied and active in their sports, and that the 2/15 poor cases were still not satisfied with the treatment. Our short-term results indicate that arthroscopic shaving targeting the area with neovessels and nerves on the dorsal side of the patellar tendon has a potential to reduce the tendon pain and allow for the majority of patients to go back to full tendon loading activity within 2 months after surgery. Further studies evaluating this new technique for treating Jumper's knee-PT are in progress.

Dynamic measurement of patellofemoral kinematics and contact pressure after lateral retinacular release: an in vitro study.
The purpose of this study was to investigate the influence of lateral retinacular release and medial and lateral retinacular deficiency on patellofemoral position and retropatellar contact pressure. Human knee specimens (n = 8, mean age = 65 SD 7 years, all male) were tested in a kinematic knee-simulating machine. During simulation of an isokinetic knee extension cycle from 120 degrees to full extension, a hydraulic cylinder applied sufficient force to the quadriceps tendon to produce an extension moment of 31 Nm. ⋯ In the deficient knee conditions the patella moved on a significant lateralised track (P = 0.04) through the entire extension cycle with a lateralised centre of patellofemoral pressure (P = 0.04) with a trend (P = 0.08) towards increased patellofemoral pressure. The results suggest that lateral retinacular release did not inevitably stabilise or medialise patellar tracking through the entire knee extension cycle, but could decrease pressure on the lateral patellar facet in knee flexion. Therefore lateral retinacular release should be considered carefully in cases of patellar instability.

Clinical, radiologic and arthroscopic assessment and treatment of bilateral discoid lateral meniscus.
The purpose of the study is to evaluate clinical, radiologic and arthroscopic features of bilateral discoid lateral meniscus and to assess the outcome of arthroscopic meniscectomy. Among the 177 arthroscopies performed for discoid lateral meniscus between January 1993 and January 2004, 12 were bilateral. The clinical and radiologic evaluation was done from the records. ⋯ This finding has not been described in the literature so far. Arthroscopic partial meniscectomy gives good results in symptomatic bilateral discoid meniscus. This to our knowledge is the largest series of bilateral discoid lateral menisci.
