Outcome Measures

Primary Outcomes (1)

  • Change from baseline pain score at 1-months, 3-months and 6-months

    Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) measures knee pain, stiffness, and physical function. The scores for each subscale are summed up, with a possible score range of 0-20 for Pain, 0-8 for Stiffness, and 0-68 for Physical Function. The sum of the scores for the three subscales gives a total WOMAC score. High scores are associated with more pain, stiffness, and poor function, while low scores indicate well-being.

    Baseline, 1-month, 3-month, 6-month

Secondary Outcomes (7)

  • Change from baseline stiffness and physical function at 1-months, 3-months and 6-months

    Baseline, 1-month, 3-month, 6-month

  • Change from baseline activity pain score at 1-months, 3-months and 6-months

    Baseline, 1-month, 3-month, 6-month

  • Change from baseline rest pain score at 1-months, 3-months and 6-months

    Baseline, 1-month, 3-month, 6-month

  • Change from baseline night pain score at 1-months, 3-months and 6-months

    Baseline, 1-month, 3-month, 6-month

  • Change from baseline quality of life at 1-months, 3-months and 6-months

    Baseline, 1-month, 3-month, 6-month

Study Arms (2)

Dextrose Prolotherapy

ACTIVE COMPARATOR

Intra-articular Injection: A total of 5 cc of 25% dextrose solution (4 cc of 30% dextrose + 1 cc of saline) will be administered to the patellofemoral joint space in each patient with the same technique using the supero-lateral technique using a sterile injector with a 20 gauge needle tip.

Procedure: Intra-articular and extra-articular Dextrose Prolotherapy injectionProcedure: Intra-articular and extra-articular Saline injection

Saline

ACTIVE COMPARATOR

Intra-articular Injection: Using a sterile syringe with a 20 gauge needle tip, a total of 5 cc of saline will be administered to the patellofemoral joint space in each patient with the same technique using the supero-lateral technique.

Procedure: Intra-articular and extra-articular Dextrose Prolotherapy injectionProcedure: Intra-articular and extra-articular Saline injection

Interventions

In the prolotherapy group, 28 patients will receive intra-articular 5 cc 25% dextrose solution (4 cc 30% dextrose + 1 cc saline) and extra-articular 10 cc 15% dextrose solution (5 cc 30% dextrose + 2.5 cc saline + 2.5 cc 1% lidocaine) in 3 sessions.Extra-articular Injection: Using a sterile syringe with a 27 gauge needle tip (Dental), the points previously found and marked with US (medial collateral ligament, lateral collateral ligament, patellar ligament and adhesion sites of coronary ligaments; pes anserine and superior patellar regions) perpendicular to the surface, using peppering technique, a total of 10 cc of 15% dextrose solution (5 cc 30% dextrose + 2.5 cc saline + 2.5 cc 1% lidocaine) will be injected in small volumes (0.5cc-1cc) at each point.Injection applications will be done at weeks 0 - 3 - 6.

Dextrose ProlotherapySaline

In the saline group, 28 patients are planned to receive 3 sessions of intra-articular 5 cc saline and extra-articular 10 cc lidocaine-serum physiologic solution (5 cc saline + 5 cc 1% lidocaine).Injection applications will be done at weeks 0 - 3 - 6.
