Background:Knee osteoarthritis (KOA) is a common disabling disease. Limited studies have demonstrated that prolotherapy with dextrose or with prolozone can be helpful in the treatment of patients with KOA.Objectives:In the current study, we compared the results between these two treatment methods.Patients and Methods:In the current randomized clinical trial, 80 patients with mild to moderate KOA were randomly assigned equally into two groups (ozone group and dextrose group). In each group, injections were repeated three times with 10-day intervals. Before the treatment and 3 months after the injections, the pain intensity was measured by using a visual analogue scale and the Western Ontario and McMaster university arthritis index scores. Finally, the results were compared between the two groups.Results:In the two groups, the pain intensity and WOMAC scores significantly decreased and increased, respectively (P < 0.001). However, there was no significant difference between the two groups.Conclusions:Prolotherapy with dextrose and with prolozone result in the same pain relief or functional improvement in patients with mild to moderate KOA.

Suction drains provide an easy and feasible method for controlling hemorrhage after total knee arthroplasty. However, there has been no compromise regarding the optimum clamping time for these drains. We conducted a randomized clinical trial in 50 patients to compare 12-hour drain clamping and continuous drainage after total knee arthroplasty in terms of wound complications, blood loss, and articular arc of motion. To eliminate any other factor except duration of clamping, we chose to compare only knees belonging to a single patient and to restrict the study to those knees undergoing surgery due to osteoarthritis. From a total of 100 knees (50 patients) studied, the 12-hour-clamping method resulted in a significantly smaller amount of postoperative blood loss (p < 0.001). The passive ranges of motion and wound complications were not significantly different between the two groups.

SummaryBackgroundAntero-medial portal (AMP) and trans-tibial (TT) techniques are the most widely used methods for drilling femoral tunnel in ACL reconstructions; yet, debate continues about the preferred method. This study seeks to compare these 2 techniques in patients with ACL tears.Material/MethodsIn this comparative study, all cases of isolated ACL reconstruction using 4-strand hamstring tendon in 2006–2010 were evaluated for eligibility. Of 266 patients, 124 cases (60 TT and 64 AMP), with the mean age of 28.48±8.3, met the inclusion criteria. Both groups were compared in 8 follow-ups from the point of view of time of: return to post-surgical activities (including walking without crutches, normal life activity, jogging, and exercising), maximum range of passive movements, knee instability (Lachman test), functional condition (subjective IKDC and Lysholm knee scores), therapeutic outcomes, and patient’s satisfaction with treatment (VAS).ResultsAMP technique significantly accelerates patients’ return to activity. AMP patients achieved full range of motion much sooner than TT cases (P<0.0001). After 1-year follow-up, S-IKDC scores were 94.8±3.9 and 89.2±4.1 and S-LKS scores were 96.1±3 and 92.2±4.1 for AMP and TT groups, respectively (P<0.0001). Knee stability was similar in both groups on Lachman test (P=0.25). AMP group patients (VAS mean score: 9.78±0.4) had greater satisfaction compared to TT group patients (VAS mean score: 9.53±0.5) (P=0.003).ConclusionsAMP technique leads to reduction in time to return to routine activities, better therapeutic outcomes and higher satisfaction rates.
