ABSTRACT

Objective:To compare the clinical efficacy of platelet-rich plasma (PRP) injection and conventional treatment for partial rotator cuff tear and analyze the possible mechanism.Methods:A prospective randomize control study was performed for clinical data of 100 patients with partial rotator cuff tear admitted to Beijing Tongren Hospital affiliated to Capital Medical University between January 2019 and December 2020. The patients were assigned to observation group ( n=50) and control group ( n=50) according to the random number table. Both groups were given conventional non-operative treatment, together with PRP injection in observation group and steroid injection in control group. The visual analogue score (VAS), Constant-Murley Score (CMS) and serum levels of inflammatory cytokines [interleukin-6 (IL-6), IL-1β, tumor necrosis factor-α (TNF-α)] were measured before and at 3, 6 months after treatment. The MRI images were also evaluated in observation group before treatment and at 6 months after treatment. Results:There were 55 males and 45 females with the age range of 40-75 years [(55.9±9.1)years]. All patients were followed up for 6.0-8.2 months [(6.2±2.9)months]. There were no significant differences between the two groups in VAS, CMS, IL-6, IL-1β and TNF-α before treatment (all P>0.05). The VAS was (3.5±0.9)points and (1.4±0.4)points] in observation group at 3, 6 months after treatment, significant lower than (4.1±0.9)points and (1.8±0.5)points in control group (all P<0.01). The CMS was (59.5±9.4)points and (86.5±7.9)points in observation group at 3, 6 months after treatment, significant higher than (53.5±8.6)points and (78.5±8.4)points in control group (all P<0.01). The serum levels of IL-6, IL-1β and TNF-α were (0.69±0.21)μg/L, (2.06±0.55)μg/L and (2.12±0.49)μg/L in observation group at 3 months after treatment, significant lower than (0.92±0.26)μg/L, (2.67±0.48)μg/L and (2.87±0.51)μg/L in control group (all P<0.01). The serum levels of IL-6, IL-1β and TNF-α in observation group [(0.37±0.11)μg/L, (1.14±0.23)μg/L, (1.27±0.25)μg/L] were also significantly lower than those in control group [(0.45±0.09)μg/L, (1.36±0.27)μg/L, (1.88±0.26)μg/L] at 6 months after treatment (all P<0.01). In both groups, the VAS, CMS and inflammatory cytokines (IL-6, IL-1β, TNF-α) showed significant improvement at 3, 6 months after treatment when compared to the pre-treatment levels (all P<0.05). Simutaneously, each group showed significant differences in each indicator at 3, 6 months after treatment ( P<0.05). In observation group, MRI showed that the high signal on the superior surface of the supraspinatus disappeared whereas the high signal in the tendon decreased at 6 months after treatment. Conclusion:For patients with partial rotator cuff tear, PRP injection can relive shoulder pain and improve shoulder function, which may be associated with the down-regulation of inflammatory responses.

ABSTRACT

BACKGROUND:In recent years,artificial cervical disc replacement surgery as a new method for the treatment of cervical disease has gradualy been accepted and understood,but relevant complications have gradualy attracted attention.OBJECTIVE:To investigate the clinical outcomes of artificial cervical disc replacement in the treatment of cervical disease and the range of motion of the replacement segment.METHODS: A total of 25 patients with artificial cervical disc replacement in the treatment of cervical spondylosis,who were treated in the Department of Orthopedics,Air Force General Hospital of Chinese PLA from August 2006 to April 2012,were enroled in this study,including 15 males and 10 females,aged 31-76 years,averagely 51.04 years.There were 6 cases of double segments and 19 cases of single segment.They were folowed up for 24 to 93 months.Clinical results were assessed using the Japanese Orthopaedic Association score,cervical dysfunction index and pain visual analog scale scores.Imaging was used to observe range of motion,cervical curvature,heterotopic ossification,and degeneration of adjacent segments.RESULTS AND CONCLUSION:Neurological function in al patients was improved to different degrees.One case suffered from mild heterotopic ossification,but no clinical symptoms were found.No significant difference in range of motion of surgical segment,and range of motion of upper and lower adjacent segments was detected between pre-replacement and final folow-up results (P>0.05).No significant difference in range of motion of C2-C7 was found between pre-replacement and final folow-up results (P>0.05).Japanese Orthopaedic Association score,cervical dysfunction index and pain visual analog scale scores were significantly improved during final folow-up compared with pre-replacement (P<0.05).These results indicated that artificial cervical disc replacement in the treatment of cervical disease can achieve better clinical efficacy,can keep the range of motion of replacement segment and avoid the accelerated degeneration of adjacent segments.
