# Stem cell therapy for knees and other aching joints *Help by Joint | Stem Cell Therapy Mesa* > Stem cell therapy for knees cannot answer every joint question. Learn what knee, hip, and shoulder soreness often feels like. ## Why does the aching joint matter? The sore joint matters because each one works differently. Knees carry your weight, hips turn with each step, and shoulders guide reaching. The usual causes of soreness also differ by joint. The movement that hurts gives the examiner useful information. ## What usually makes a worn knee complain? A worn knee may feel stiff, swollen, rough, or unsteady. Stairs and low chairs often make the ache stronger. Worn cartilage can also make bending feel less smooth. Your first few steps after rest may hurt the most. Errands, golf, or standing awhile may bring soreness later. The knee won't always complain while you are active. Notice whether the ache starts that evening or the next morning. That timing can help during an exam. ## How can hip and shoulder soreness feel different? Hip trouble may be felt in the groin, thigh, or outer hip. It'll sometimes start after sitting or during a long walk. Shoulder trouble may appear only when you reach overhead or behind you. Show the examiner which movement brings the soreness. Clicking, weakness, or trouble lying on one side also matters. Say whether the ache stays near the joint or travels farther. You won't need to know the cause before the visit. The exam can't be done from a description alone. ## When should the joint be examined? Arrange an exam when repeated aching limits sleep or normal chores. A major injury, sudden weakness, or a numb limb needs quicker care. Fever with a hot, swollen joint also calls for prompt care. Don't bend or load that joint again just to check it. For less urgent soreness, note how long it has lasted. Tell the examiner what you tried and whether it helped. Mention any fall or sudden change before the aching began. Those facts can make the exam more useful. ## What may help while I wait for the visit? Gentle movement may help when there hasn't been a fresh injury. Try a brief walk, then rest before the joint grows sore. You'll learn whether heat or cold feels better. Don't force a motion when soreness turns sharp. For the visit, remember which activity caused trouble and when it hurt. Don't forget what made the soreness ease. These details won't name the cause by themselves. They'll tell the examiner what changed during your day. ## Sources 1. In a 480-patient, four-arm, multicenter randomized phase 2/3 trial, none of three orthobiologic cell injections - autologous bone marrow aspirate concentrate, autologous adipose stromal vascular fraction, or allogeneic umbilical cord tissue-derived mesenchymal stromal cells - was superior to any other, or to a corticosteroid injection control, on pain at 12 months.

A meta-analysis of 14 placebo cohorts across 13 Level I trials in 1,076 knee osteoarthritis patients found that intra-articular saline - the placebo - produced pain and function improvements exceeding the minimal clinically important difference at 3 and 6 months.

A 2025 meta-analysis of 73 double-blind placebo-controlled injection trials in 5,895 knee osteoarthritis patients found placebo responder rates above 50 percent at 1, 3 and 6 months, declining by 12 months - which is why any uncontrolled 'our patients improved' claim from a clinic is uninterpretable.

A systematic review of 13 phase I/II randomized trials of MSC injections found 10 of 11 studies reporting cartilage outcomes described a benefit on cartilage volume, morphology or quality - but 16 eligible trials remained unpublished, which is exactly the pattern that inflates an apparent effect.
