A hip exam comes before a planned blood-based treatment

Warning signs need medical help before a clinic appointment

When a fever comes with sudden heat and swelling in the hip, an infection is possible. Get medical help soon because a joint can be harmed quickly.

After a fall, seek help when standing on that leg isn't possible. A shortened or turned-out leg also needs fast attention.

New weakness, numbness, or sudden trouble controlling your bladder or bowels may start in the back. These symptoms can't wait for an ordinary hip appointment.

Soreness that quickly worsens or repeatedly wakes you needs a closer look. I'd call my regular doctor and explain exactly what changed.

Wait on the paid hip procedure until the pain source is clear

The hip joint, outer-hip tissue, and back can cause similar soreness. Don't pay for platelet-rich plasma (PRP), which an office makes by concentrating your blood, until an exam finds the painful area.

Mention blood thinners, bleeding trouble, infection, and other health concerns. Also mention a planned hip replacement or recent joint procedure.

Take your list of medicines and old hip reports to the exam. You won't have to recall every detail while you're worried.

Ask who will perform the procedure and where it will happen. Get a phone number to use if warmth, swelling, fever, or soreness gets worse.

Tell someone in your home if walking suddenly feels unsafe. They can arrange a call or ride when you can't manage it alone.

Until the exam is done, avoid movements that sharply raise the ache. Keep notes on falls, fever, weakness, and changes in walking.

A randomized, double-blind, placebo-controlled trial in a Japanese population tested leukocyte-POOR PRP specifically in mild-to-moderate knee OA WITH joint effusion or bone marrow lesions - i.e. a selected inflammatory phenotype rather than all comers. Recorded here because phenotype selection, not the product, is the most plausible explanation for why PRP trials disagree with one another.

A CDC-led national public health investigation identified culture-confirmed bacterial infections in 20 patients (median age 63) across 8 US states who received umbilical cord blood-derived products marketed as stem cell treatment for pain, osteoarthritis, rheumatoid arthritis and injury. ALL BUT ONE REQUIRED HOSPITALISATION. Of unopened, undistributed product vials sampled, 65% (22 of 34) were contaminated with at least one of 16 bacterial species, mostly enteric; whole-genome sequencing linked an Arizona patient isolate to product administered in Florida.

A four-arm, multicentre, single-blind phase 2/3 randomized trial of 480 knee OA patients (KL II-IV) compared autologous bone marrow aspirate concentrate, autologous adipose stromal vascular fraction and allogeneic umbilical-cord-tissue mesenchymal stromal cells against a corticosteroid injection control. At 12 months NONE of the three orthobiologic injections was superior to another, or to the corticosteroid control, and none of the four groups showed a significant change in MRI osteoarthritis score from baseline. No procedure-related serious adverse events occurred.

Notably it does NOT strongly recommend any biologic injectable.

The AAOS evidence-based clinical practice guideline on Management of Osteoarthritis of the Hip states verbatim: STRONG evidence supports intra-articular corticosteroids to improve function and reduce pain in the SHORT TERM; STRONG evidence does NOT support intra-articular hyaluronic acid, because it does not perform better than placebo for function, stiffness and pain; STRONG evidence supports physical therapy for mild to moderate symptoms; STRONG evidence supports NSAIDs for short-term pain and function; and MODERATE evidence does not support glucosamine sulfate.
