Platelet-Rich Plasma Injections in Chronic Lateral Ankle Instability: A Case Series.

The platelet-rich plasma (PRP) approach may be an effective treatment for joint and cartilage pathologies. However, the rationale for its effectiveness on joint instability is limited. This study aimed to assess the safety and effectiveness of PRP injections in patients with chronic lateral ankle instability (CLAI). This retrospective study was performed at a single-center outpatient clinic between January 2015 and February 2023 and included pre-intervention assessment and short-term follow-up. Patients were excluded if they had received previous surgical treatment or had constitutional hyperlaxity, systemic diseases, or grade II or III osteoarthritis. The clinical and functional evaluation consisted of the Karlsson score, the Cumberland Ankle Instability Tool (CAIT), Good's grading system, the patient's subjective satisfaction level, and the time required to return to exercise. The entire PRP therapy regime consisted of three PRP administrations at 7-day intervals and follow-up appointments. PRP was administered both intraarticularly and into talofibular ligaments. A total of 47 consecutive patients with CLAI were included, 11 were female (23.4%), with a mean age at intervention of 31.19 ± 9.74 years. A statistically significant improvement was found in the CAIT and Karlsson scores at 3 months (27.74 ± 1.68 and 96.45 ± 4.28, respectively) relative to the pre-intervention status (10.26 ± 4.33 and 42.26 ± 14.9, respectively, p < 0.000). The mean follow-up of patients with CLAI was 17.94 ± 3.25 weeks. This study represents successful short-term functional and clinical outcomes in patients with CLAI after PRP treatment, with no adverse effects. It demonstrates the feasibility of a randomized controlled trial to further assess this therapy.

Platelet-rich plasma in the management of trigger finger: A case report.

Platelet-rich plasma (PRP) has emerged as a viable therapeutic alternative for a number of clinical applications and has potential benefit for use in trigger finger. However, PRP use has not been previously reported for this condition. We report a 63-year-old woman sustaining a refractory trigger finger after a series of three PRP injections over a 2-week period. There was resolution of triggering, with no symptom recurrence at 3-month follow-up. On the basis of this report, we can assume that the treatment of trigger finger with PRP is a promising therapeutic option to be further explored with larger samples and high-quality studies.

Clinical and Functional Outcome of Meniscal Injuries Treated with Platelet-Rich Plasma: A Single-Center Case Series.

Meniscal injuries are among the most frequently encountered conditions in the knee joint. Therapeutic approaches are diverse and are largely dependent on the extent and location of the injury. The purpose of this study was to describe the clinical and functional outcomes of an intraarticular and percutaneous platelet-rich plasma (PRP) injection regime in patients with stable meniscal injuries. Demographics, the type of tear, affected knee, surgical procedure, type of intervention, follow-up period, and outcomes were recorded in all cases. Patient-reported outcome measures included the Knee Injury and Osteoarthritis Outcome Score (KOOS) and Tegner activity level scale. Overall patient satisfaction, quality of life, and pain intensity were also assessed. A total of 38 cases (8 females) had sustained a stable meniscal lesion (32 medial, 6 lateral) and met the inclusion criteria. All of them received three intraarticular and percutaneous PRP injections. Patients receiving the PRP injection regime reported clinically (p = 0.000) and functionally (p = 0.000 and p = 0.001) significant improvement in all outcome measures during this interval. All patients reported they were very satisfied or satisfied with the outcome. The results of this study suggest that the treatment of stable meniscal injuries with percutaneous-intraarticular PRP injections can achieve a significant clinical and functional improvement.

Platelet-rich plasma for thumb carpometacarpal joint osteoarthritis in a professional pianist: case-based review.

Thumb carpometacarpal osteoarthritis (TCMC-OA) is a progressively disabling, debilitating condition presenting with thumb base pain and hand functional impairment. Platelet-rich plasma has been used widely for the management of musculoskeletal pathologies, OA being among them. To our knowledge, only a few cases have been previously reported on this topic until now. A 59-year-old male professional pianist presented with chronic, mild onset of right thumb base pain involving a progressive lack of pinch strength in his right hand, and severe difficulties with playing. Three PRP injections were administered to the TCMC joint on a 1-week interval regime. Clinical outcomes were assessed by using the visual analog scale (VAS) for pain, grip and pinch strength, and the Quick-DASH Questionnaire. Functional outcome was excellent according to patient's capability with daily living activities and specific playing demands. At 12 months follow-up, no recurrences or complications were identified, with the musician returning to his previous level of performance 2 weeks before the end of this period. Patient self-reported satisfaction was high and he reported to return to his routine piano activity with no limitations. This case-based review study documents the clinical efficacy of PRP treatment from both functional and perceived-pain perspectives in a professional pianist. Presenting this case, our aim is to draw attention of healthcare providers dealing with TCMC-OA to PRP as a safe, beneficial therapy for this condition which needs further assessment in randomized controlled trials.
