Abstract
Shoulder pain is the third most common musculoskeletal complaint of the general population, with a prevalence of shoulder pain of 16-26%. RCTs are a common cause of chronic shoulder pain and disability, with the supraspinatus partial thickness tendon tears constitute 50% of patients complaining of shoulder pain.Many patients are refractory to standard conventional non-operative treatment while the results of surgical repair of RTC are somewhat controversial and depend on age of patient and size and duration of the tear. No therapy has been shown to uniformly improve clinical, functional and radiological outcomes of RCT, and no therapy specifically targets the presumed degenerative pathology of RCT.Tendons have limited regeneration ability. Hence, new treatment modalities targeting the underlying degeneration such as PRP could be an option for the treatment of this pathology. PRP injection presumed to provide the necessary cellular and humeral mediators to induce a healing cascade and hence may improve pain and functional outcomes in supraspinatus PT-RCT.The aim of the present study is to evaluate the efficacy of PRP injection in comparison to physical therapy for treatment of chronic partial supraspinatus tears.The study included 40 patients with chronic partial tear of the supraspinatus tendon randomized into two groups. PRPinj-G included 20 patients who received 3 injections of PRP, one subacromial and two intratendinous, under ultrasound guidance. The PhT-G included 20 patients who received 9 treatments of laser, ultrasound, TENS and exercise. Both groups were instructed afterwards for a home exercise program. VAS-pain, DASH scores and active shoulder ROM were evaluated at baseline and at 6 and 12 weeks post intervention. Ultrasound measurement of tear size was recorded at baseline and at 12 weeks post intervention in the two groups.The results of the study revealed that:VAS pain score showed significant decrease in the two treatment groups at 6-weeks post-intervention in comparison to the baseline and showed a further decrease at 12-weeks post-intervention. VAS-pain score was significantly lower in PRPinj-G than PhT-G at 6- and 12-weeks post-intervention. Similarly, DASH score showed significant decrease in the two treatment groups at 6-weeks post-intervention in comparison to the baseline and showed a further decrease at 12-weeks post-intervention. DASH score was significantly lower in PRPinj-G than PhT-G at 6- and 12-weeks post-intervention.Shoulder active flexion and extension were significantly better in PRPinj-G than PhT-G at 6- and 12-weeks post-intervention. In PRPinj-G, shoulder flexion and extension were improved at 6-weeks with further improvement at 12-weeks post-intervention compared to baseline. The improvement of the shoulder flexion and extension in PhT-G at 6- and 12-weeks post-intervention in comparison to baseline was insignificant.
