| خلاصه مقاله | Background and Aim: Platelet-rich derivatives are being increasingly used in the treatment of
tendon-related pathologies as a rich source of growth factors which aims at providing a
regenerative stimulus in the tendon. We sought to ascertain if local application of platelet
lysate(PL) to augment rotator cuff repair improves outcomes compared to ketorolac tromethamine
treated group.
Methods: A total of 40 patients,18 to 70 years,with diagnosis of RCT and symptoms for ≥3 months
were randomized to receive sub-acromial injections of PL (2 ml) every week for a total of 3
injections and two injection of ketorolac tromethamine (30 mg) every two weeks in addition to a
training program.PL from all participants was prepared following standard protocols.Patients were
randomized into a PL group (n=20) and ketorolac (control group,n=20).Visual Analogue Scale
(VAS), Shoulder Pain and Disability Index (SPADI) and shoulder range of motion (ROM) were
assessed at baseline and at 1 and 6 months after injection.
Results: 40 patients completed 6 months follow-up. Within each group, SPADI and VAS scores
showed significant improvements compared with baseline at all-time points (P<0001). In the range
of motion measures, no significant difference after ketorolac therapy was noted. The outcomes
were identical at the initial and short-term state in both control and PL groups; whereas,when
considering the 6-month period, there is a seemingly remarkable superiority in PL group in all
parameters
Conclusion: This study suggests that local injection of PL led to favorable clinical outcomes for
the RCT treatment after 6 months and supports that PL probably has the capability of improving
the symptoms and bringing back the functionality in capacities. Hence,these consequences can
open doors for PL a new horizon as well as a second choice for RCT treatment in the future. |
