Outcome Measures
Primary Outcomes (2)
Knee injury and Osteoarthritis Outcome Score (KOOS)
The KOOS's five patient-relevant dimensions are scored separately: Pain (nine items); Symptoms (seven items); ADL Function (17 items); Sport and Recreation Function (five items); Quality of Life (four items). A Likert scale is used and all items have five possible answer options scored from 0 (No problems) to 4 (Extreme problems) and each of the five scores is calculated as the sum of the items included. Scores are transformed to a 0-100 scale, with zero representing extreme knee problems and 100representing no knee problems as common in orthopedic scales and generic measures. Scores between 0 and 100 represent the percentage of total possible score achieved.
during the follow-up period for 2years (2 weeks, 4 weeks, 6 weeks, 6 months, 1 year, and 2 years postoperatively)
Kujala Score (Anterior Knee Pain Scale - AKPS)
The Kujala Score or Anterior Knee Pain Scale (AKPS) is a 13-item self-report questionnaire that assesses subjective reactions to particular activities and symptoms that are known to correlate with anterior knee pain syndrome. The AKPS is graded on a scale of 0 to 100, with 100 being the highest possible score. Lower scores reflect greater pain and disability.
during the follow-up period for 2 years (2 weeks, 4 weeks, 6 weeks, 6 months, 1 year, and 2 years postoperatively)
Study Arms (2)
Group (A)
ACTIVE COMPARATORThe patients will undergo open wedge high tibial osteotomy with arthroscopic partial lateral patellar facetectomy.
Group (B)
ACTIVE COMPARATORThe patients will undergo open wedge high tibial osteotomy without arthroscopic partial lateral patellar facetectomy.
Interventions
All procedures will be performed based on the technique recommended by the AO international knee expert group. Biplanar osteotomy, which comprises osteotomies in the axial and frontal planes, will be performed in all cases. Ascending frontal osteotomy, leaving the tibial tuberosity on the distal fragment, will be also performed. All osteotomies will be performed without the use of additional bone grafts, and the opening of the osteotomy was maintained with a Tomofix plate (Orthomed-E Co., Egypt). Wound closure will be performed in layers.
Diagnostic arthroscopy will be performed in all cases to assess Patellofemoral articular cartilage degeneration , assess the lateral compartment and exclude any other pathology. The knee is taken throughout a range of motion to directly visualize the impingement of the lateral patellar facet against the trochlea. Next, a radiofrequency probe is used to outline the area to be resected along the lateral patellar facet While maintaining the knee at 20 degrees of flexion, a 5.5-mm burr is introduced, and under arthroscopic visualization, the overhanging portion of the lateral patellar facet is carefully resected. Once the bony resection is complete, the knee is dynamically re-evaluated (through flexion and extension) for residual impingement and to assess for improvements in patellar mobility. Patellar tracking is assessed to verify that there is no catching in flexion and that patellar mobility is improved.
Eligibility Criteria
You may qualify if:
- Age 35-60years
- Mild to moderate TFOA (G I-II-III) Kellgren-Lawrence (KL) scale (16)
- Anterior knee pain (PFOA)
- No involvement of the lateral compartment
- range of motion of at least 120° flexion
- Body mass index (BMI) \<30kg/m2
- varus angle degree \<10°
You may not qualify if:
- advanced case of TFOA (G VI KL scale), which requires total knee replacement.
- flexion deformity ≥15°
- inflammatory disease (such as rheumatoid arthritis).
