Evaluation of orthobiological ozonized platelet-rich plasma therapy post-arthroscopic suturing and lone partial meniscectomy in the treatment of meniscal tears within degenerative knee osteoarthritis.

Background: Knee joint osteoarthritis (OA)-related meniscal tears are still sometimes treated in centers by arthroscopic partial meniscectomy (APM), which is then followed by a solitary physical therapy regimen.

Objective: The present study was conducted to compare the efficacy of intra-articular injection of ozonized platelet-rich plasma (PRP) and hyaluronic acid following arthroscopic suturing, and APM to treat meniscal tear degenerative type.

Methods: In a randomized trial of prospective comparative research, 104 patients, all of whom had meniscal tears due to OA of the knee, were randomly divided into two groups. The participants in Group A (55 patients) were given intra-articular ozonized PRP and hyaluronate therapeutics, following arthroscopic suturing of meniscal tear treatment (ASMT) of degenerative knee joint OA. Group B (49 patients) was prepared for APM alone. Both groups were followed by physical therapy and a follow up visit throughout 12, 24, and 36 months. The WOMAC and Lequesne scores were evaluated.

Results: At every follow up visit for 6, 12, and 24, months, there was a significant decline in the mean of WOMAC and Lequesne scores in Groups A and B relative to baseline. Additionally, Group A significantly (P<0.0001) outperformed Group B at 12, 24, and 36 months for both Lequesne's and WOMAC scores. There were infection, stiffness, and widespread OA knee degeneration detected in Group B while no serious adverse effects were observed in Group A.

Conclusion: The study's findings demonstrated that physical and intra-articular orthobiological ozonized PRP and hyaluronate therapies were more effective than APM in treating degenerative knee joint OA.
