Chronic knee pain, tennis elbow, plantar fasciitis, rotator cuff trouble, and other tendon and joint problems can take over a weekend on Clear Lake or a workday at NASA Johnson Space Center, UTMB, Methodist Clear Lake, a Bayport refinery, or a Galveston Bay marina. When rest, physical therapy, and over-the-counter medications stop providing meaningful relief, PRP injections offer a non-surgical regenerative option for patients across the Clear Lake and Bay Area Houston community. Platelet-rich plasma therapy concentrates growth factors from the patient’s own blood and delivers them directly to damaged tissue under ultrasound guidance, where they may help reduce pain and support repair (Everts et al., Int J Mol Sci, 2020).
At the League City office of Performance Pain and Sports Medicine, located on East Main Street just minutes from I-45, Dr. Suzanne Manzi performs PRP injections as part of a comprehensive interventional pain and regenerative medicine practice. The Bay Area office offers PRP candidacy evaluations and ultrasound-guided injections without the long drive into the Texas Medical Center.
What Is Platelet-Rich Plasma (PRP) Therapy?
PRP therapy is an injectable treatment made from a patient’s own blood. A small blood sample is processed in a centrifuge to separate and concentrate the platelets, which contain growth factors at levels 5 to 10 times higher than normal blood (AAOS OrthoInfo). These growth factors, including PDGF, TGF-beta, and VEGF, support the body’s natural inflammation and tissue repair processes (Everts et al., Int J Mol Sci, 2020).
Because PRP is autologous (made from the patient’s own blood), there is no risk of allergic reaction or disease transmission. PRP is not stem cell therapy, not a steroid injection, and not a surgical procedure. It is a regenerative injection that works by amplifying the body’s existing healing response.
Who Is a Candidate for PRP Injections in League City?
PRP injections may help patients with a range of musculoskeletal conditions. The strongest clinical evidence supports PRP for mild to moderate knee osteoarthritis, where multiple meta-analyses show clinically meaningful improvement in pain and function (Bensa et al., Am J Sports Med, 2025). Many of the Bay Area patients we evaluate at the League City office are active retirees and pre-retirees boating Clear Lake and Galveston Bay, NASA contractors and aerospace workers, refinery shift workers, UTMB and Methodist Clear Lake clinicians, Clear Creek ISD educators, and weekend athletes whose recreational sports have caught up with them.
PRP is commonly used at the League City office for tendon conditions, including:
- Tennis elbow (lateral epicondylitis) — common in tennis and pickleball players, dental and surgical providers, and process operators with repetitive forearm work
- Rotator cuff tendinopathy — common in overhead-sport athletes, refinery and Ship Channel workers, and patients with chronic postural strain
- Plantar fasciitis — common in long-shift healthcare workers, runners on Bay Area trails, and patients who spend long hours on concrete plant floors
- Sports injuries involving tendons and ligaments
Some Bay Area patients with spine and back pain may benefit from PRP when used alongside other interventional approaches such as facet joint injections. The League City office offers PRP as part of an integrated pain plan for select spine and back pain patients when the clinical picture supports it.
Patients with active infections, blood clotting disorders, or certain cancers may not be candidates. A physician evaluation in League City determines whether PRP is appropriate for the specific condition, joint, or tendon involved.
How PRP Injections Work
The PRP injection process at Performance Pain and Sports Medicine follows four steps:
- Consultation and evaluation. A physician reviews the patient’s condition, imaging, and treatment history to confirm PRP is appropriate.
- Blood draw. A small blood sample is drawn from the patient’s arm, similar to a routine lab draw.
- Centrifuge processing. The sample is placed in a centrifuge for 15 to 20 minutes, separating the platelet-rich layer from the rest of the blood.
- Ultrasound-guided injection. The concentrated PRP is injected into the target joint, tendon, or tissue using real-time ultrasound guidance for precision placement.
The entire visit typically takes 45 to 60 minutes. Ultrasound guidance helps ensure the PRP reaches the exact target area.
Benefits of PRP Therapy
PRP therapy offers several practical benefits for the Bay Area patients we treat at the League City office:
- Uses the body’s own healing factors with no synthetic drugs or foreign substances — an important consideration for NASA contractors and refinery workers in safety-sensitive roles where every medication choice matters
- Minimal downtime, with most patients resuming normal activities within a few days, including a return to a console shift at JSC, a refinery rotation, or a weekend on the boat
- May reduce or delay the need for surgery in some patients with joint or tendon conditions
- Can provide longer-lasting relief than some alternatives. One meta-analysis showed PRP outperforming hyaluronic acid injections (OR 2.19, P=.002) for knee osteoarthritis outcomes (Oeding et al., Am J Sports Med, 2024)
Results vary depending on the condition treated, the PRP preparation method, and the platelet concentration used. Not all patients respond the same way, and the League City team will tell you honestly whether your specific imaging and clinical picture make PRP a reasonable next step.
Risks and Side Effects
PRP injections are considered safe, with a low risk of serious side effects. Because PRP is made from the patient’s own blood, there is no risk of allergic reaction or transmitted infection (Sheean et al., Arthroscopy, 2021).
The most common side effects are mild and temporary:
- Soreness or swelling at the injection site (typically 1 to 3 days)
- Temporary stiffness in the treated area
- Bruising at the blood draw or injection site
Rare risks include infection or nerve irritation. The treatment team discusses all potential risks before the procedure.
PRP vs Corticosteroids and Other Treatments
Corticosteroid injections often provide faster initial pain relief, sometimes within days. However, evidence suggests that PRP may deliver better results at 3 to 6 months and beyond. For tendinopathy, one meta-analysis of 27 trials found that PRP provided superior mid-term pain relief compared to corticosteroids for tennis elbow, plantar fasciitis, and rotator cuff conditions (Ye et al., BMC Musculoskelet Disord, 2025).
For knee osteoarthritis, PRP also appears to outperform hyaluronic acid at 6 and 12 months (Filardo et al., Cartilage, 2020). Performance Pain and Sports Medicine offers PRP as part of a multimodal treatment plan that may also include epidural steroid injections, radiofrequency ablation, and physical therapy. The right approach depends on the patient’s diagnosis, pain severity, and treatment goals.

How much do PRP injections cost in League City?
PRP injections are typically a cash-pay procedure, as most insurance plans currently classify PRP as experimental. Cost varies based on the area being treated and the PRP preparation method used. Contact the League City office at 346-217-1111 for current pricing and to discuss payment options.
Are PRP injections covered by insurance or Medicare?
Most insurance plans and Medicare currently classify PRP as experimental and do not cover it. The League City staff can help verify individual coverage, discuss payment options, and identify any related interventional procedures (such as facet joint injections or steroid injections) that may be covered.
How many PRP injections will I need?
Most League City patients receive one PRP injection, which can be repeated if additional treatment is needed. The decision to repeat depends on the condition treated, the patient’s response to the initial injection, and the treating physician’s evaluation of ongoing symptoms.
How long do PRP injection results last?
Many patients experience relief lasting 6 to 12 months or longer. For knee osteoarthritis, studies show PRP benefits can persist at 12 months, and some patients maintain improvement beyond that timeframe. Results depend on the condition, the PRP preparation, and the patient’s overall musculoskeletal health.
Does PRP really work?
Research shows mixed results depending on PRP preparation, but multiple meta-analyses suggest meaningful benefit for knee osteoarthritis when higher platelet concentrations are used (Bensa et al., Am J Sports Med, 2025) and for tendinopathies including tennis elbow and plantar fasciitis. The evidence is stronger for some conditions than others, which is why honest candidacy conversations matter.
How soon can I walk after a PRP injection?
Most patients can walk the same day. Light activity is typically fine within 24 to 48 hours. Physicians generally recommend avoiding strenuous exercise — including running on Bay Area trails and intense gym sessions — for 1 to 2 weeks to allow the healing process to begin.
How does PRP compare with cortisone shots?
Cortisone shots tend to provide faster initial relief but their effect often fades by 3 months. PRP tends to be slower to take effect but produces better outcomes at 6 and 12 months for many tendon and knee osteoarthritis conditions. The League City team will help match the right injection to your specific condition rather than defaulting to one for everyone.
