About this study
Official title: Functional Effects of Postoperative Conventional Physiotherapy Following Cosmetic Femoral Lengthening Using the Lengthening Over Nail (LON) Technique
This study aims to understand how an early postoperative conventional physiotherapy program affects daily movement and physical function in adults who undergo cosmetic femoral lengthening surgery using the Lengthening Over Nail (LON) technique.
Participants aged between 18 and 45 years who have this surgery will take part in a structured physiotherapy program. The study will examine changes in physical function, pain, walking ability, and independence before surgery, during recovery, and after removal of the external fixator.
The results of this study may help improve rehabilitation planning after cosmetic femoral lengthening surgery.
Read the detailed description
This interventional study will evaluate the effects of an early postoperative conventional physiotherapy program in individuals who undergo cosmetic femoral lengthening surgery using the Lengthening Over Nail (LON) technique.
A total of 54 healthy adults aged between 18 and 45 years will be included. Participants will be assessed at three time points: before surgery, at the eighth postoperative week, and one week after removal of the external fixator.
Following surgery, participants will be monitored in the hospital for one week. After discharge, they will receive a standardized conventional physiotherapy program five days per week for a total of thirteen weeks. The program will include joint mobilization exercises, muscle stretching and strengthening exercises, neuromuscular electrical stimulation, gait training with assistive devices, and functional exercise training.
Outcome measures will include functional capacity, pain intensity, functional mobility, and functional independence. Data will be analyzed using appropriate statistical methods to evaluate changes over time.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Conventional Physiotherapy ProgramBehavioural
The planned rehabilitation program included active and passive joint mobilization, quadriceps and hamstring stretching, isometric strengthening, NMES, cryotherapy, assistive-device-supported ambulation training, elastic-band resistance exercises, and modified apparatus-based Pilates, supervised by a physiotherapist five days per week for 13 weeks. In actual implementation, structured rehabilitation began on postoperative day 7. Daily cryotherapy during postoperative days 0-6 was routine inpatient care and was not part of the study rehabilitation program. Cryotherapy was applied at every supervised session during rehabilitation weeks 1-4 and thereafter only when edema persisted. Superficial thermotherapy was used as supportive physiotherapy when clinically indicated for muscle tightness or stiffness before stretching or mobilization; it was not provided to every participant or at every session.
| Study group | Role | What they receive |
|---|---|---|
| Conventional Physiotherapy Group | Experimental | Participants assigned to this arm will receive a structured conventional physiotherapy program following cosmetic femoral lengthening surgery performed using the Lengthening Over Nail (LON) technique. The rehabilitation program will be initiated in the early postoperative period and will include active and passive joint mobilization exercises, quadriceps and hamstring stretching, isometric muscle strengthening, neuromuscular electrical stimulation (NMES), cryotherapy, and functional mobilization with assistive devices. Physiotherapy sessions will be conducted five days per week under the supervision of an experienced physiotherapist. Receives: Behavioral: Conventional Physiotherapy Program |
What is being measured
The primary outcome is the main question the study is designed to answer.
Functional Capacity Assessed by the 30-Second Chair Stand Test
The 30-Second Chair Stand Test is used to assess lower extremity functional strength and overall functional capacity. Participants are instructed to stand up and sit down from a standard chair as many times as possible within 30 seconds. A higher number of repetitions indicates better functional capacity.
Measured: Preoperative baseline, postoperative 8th week, and 1 week after removal of the external fixator
Secondary outcomes (1)
Functional Mobility Assessed by the Timed Up and Go Test
The Timed Up and Go Test is used to assess functional mobility and dynamic balance. Participants are instructed to stand up from a chair, walk three meters, turn around, walk back, and sit down. Shorter completion times indicate better functional mobility.
Measured: Preoperative baseline, postoperative 8th week, and 1 week after removal of the external fixator
