Effect of adding dexmedetomidine to intra-articular levobupivacaine on postoperative pain following arthroscopic meniscus surgery: A prospective, double-blind, randomized, placebo- controlled, clinical trial

OBJECTIVE

The aim of this study was to determine the effect of adding dexmedetomidine to intra-articular levobupivacaine on postoperative pain levels and analgesic requirements following arthroscopic meniscectomy.

METHODS

A total of 60 American Society of Anesthesiologist physical status I-II patients, aged 20 to 62 years, and scheduled for arthroscopic partial meniscectomy under general anesthesia were included in this study. All the patients were randomly assigned to one of four groups (15 patients in each group): Group 1 (8 male, 7 female; mean age = 46.70 ± 13.13 years; 0.9% isotonic 20 ml), group 2 (7 male, 8 female; mean age = 42.60 ± 12.18 years; levobupivacaine 0.5 mg/kg plus 0.9% isotonic), group 3 (8 male, 7 female; mean age = 43.80 ± 12.63 years; 1μg/kg dexmedetomidine plus 0.9% isotonic), and group 4 (7 female, 8 male; mean age = 40.40 ± 11.79 years; levobupivacaine 0.5 mg/kg plus 1μg/kg dexmedetomidine and 0.9% isotonic). All medications were administered at the end of arthroscopic surgery. Pain levels were measured using a Visual Analogous Scale (VAS) and Verbal Rating Scale (VRS) at postoperative 1, 2, 4, 6, 12, and 24 hours.

RESULTS

VAS scores at rest were significantly lower in Group 4 at postoperative 1th, 2nd, 4th, 6th,12th, and 24th hours than in other groups. The time to take the first analgesic was significantly higher in Group4 (964 ± 288 min), and total analgesic consumption was significantly lower in Group 4 compared to those of other groups.

CONCLUSION

Although administration of intra-articular dexmedetomidine alone may have a weaker effect than intra-articular levobupivacaine on postoperative pain relief after arthroscopic partial meniscectomy, adding dexmedetomidine to intra-articular levobupivacaine may increase the durationand quality of postoperative analgesia without any side effect.

Kinesio taping as a treatment method in the acute phase of ACL reconstruction: A double-blind, placebo-controlled study

OBJECTIVE

In this study, we aimed on investigating the effects of Kinesio taping (KT) in acute postoperative rehabilitation phase of anterior cruciate ligament (ACL) reconstruction.

METHODS

Thirty male patients (mean age: 28.1 years) with ACL reconstruction were randomly assigned to two groups: (1) an experimental group to receive a KT treatment through the muscle and lymphatic correction techniques; or (2) a control group for sham KT. Both interventions were applied twice during a 10-day period from the fourth postoperative day. All patients received the same rehabilitation program for three months. The groups were compared according to range of motion (ROM), pain, swelling and muscle strength before treatment and on the fifth and tenth treatment days. Subjective evaluations were made with the Lysholm, modified Cincinnati and Tegner scores on the first and third postoperative months.

RESULTS

Intragroup comparisons showed significant improvements in both groups on the fifth and tenth day and first and third month evaluations (p < 0.05). In comparison to the control group, the experimental group showed significant improvements in swelling around the patella, all pain measurements and hamstring muscle strength on the fifth KT day and knee flexion range of motion (ROM), night pain, all swelling measurements and hamstring muscle strength on the tenth KT day (p < 0.05).

CONCLUSION

Our results revealed that KT techniques applied in addition to the acute rehabilitation program of ACL reconstruction are beneficial in treatment of pain, swelling, knee flexion ROM, and hamstring muscle strength.

Weight bearing the same day versus non-weight bearing for 4 weeks in Achilles tendon rupture

INTRODUCTION

Achilles tendon rupture (ATR) often occurs in 40- to 50-year-old men. Multiple studies discuss the correct treatment strategy based on surgical or nonsurgical intervention, including early mobilization. We aimed to compare the outcomes of bearing weight on the same day with non-weight bearing over a 4-week period of ATR patients.

MATERIALS AND METHOD

Forty-seven ATR patients were conservatively treated and entered into our study. Group 1 consisted of 23 patients treated with partial weight bearing beginning the same day of conservative treatment; Group 2 consisted of 24 patients treated with non-weight bearing after a 4-week period. Patients were at least 18 years old and were followed for 12 months. Evaluation criteria were mechanism of injury, admission time to our clinic, complication rate, and time to return to work. Symptoms and physical activity levels of all patients were assessed on 6 and 12 months after treatment began, according to the Achilles Tendon Total Rupture Score (ATRS), Physical Activity Scale (PAS), and American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score.

RESULTS

Rerupture rates were rate 17.4% (4 patients) in Group 1 and 12.5% (3 patients) in Group 2 (p = 0.81). Time to return to work was shorter in Group 1 compared with Group 2, but it was not statistically significant (p = 0.86). AOFAS, ATRS, and PAS scores at 6 and 12 months showed no significant differences between groups (p = 0.69, p = 0.59, p = 0.89, p = 0.77, p = 0.94, p = 0.66, respectively).

CONCLUSION

This study showed that a well-conducted early-weight-bearing treatment has good clinical outcomes, with a complication rate no higher than non-weight-bearing treatment.
